• Ignored unknown tool paths (e.g. connectors) rather than crashing.

• Use the operation's technology if it is not specified on a toolpath.

Changes in release 9.51 (2012-10-26)

• Correction to the APT CL parser for NX.

Changes in release 9.50 (2012-09-29)

Changes in release 9.49 (2012-06-29)

• Corrected issues with tool units.

Changes in release 9.48 (2012-06-22)

• Corrected issues with APT parsing of MULTAX and COOLANT statements.

Changes in release 9.47 (2012-06-22)

• DLL fixes to correct feedrates for metric models. This problem affected the MasterCAM export plugin.

• Updated Mazak machine tool model to correct some minor issues with the tool changer kinematics.

Changes in release 9.45 (2012-06-08)

• Extended machine tool menu with a "Show Extra Machine Motions" submenu containing any extra kinematic motions defined for the current machine. Selecting a motion will execute it.

Changes in release 9.44 (2012-06-06)

Changes in release 9.42 (2012-05-21)

• Fixed some viewing problems related to degenerate closed loops and unset values in presentation information.

Changes in release 9.41 (2012-04-16)

• Replaced the Mazak VQC 20 machine model with one that has better axis limit information, which should correct the limit issues with the previous version.

• Corrected an internal problem that prevented axis limit exceeded messages were not being shown. Also changed the display so that they are now shown in a larger font at the bottom of the geometry window.

Changes in release 9.40 (2012-04-13)

• Added Mazak VQC 20 machine model with AP242 kinematics. Note that the machine limits for this model may still need adjustment, so you may need to move the part around using the Machine Tool | Adjust Mount Point dialog.

• Updated machine kinematics processor to handle the case where a single kinematic_link_representation_association is referenced by multiple context_dependant_kinematic_link_representation objects.

• Reversed the high and low limits of the axes on the workpiece chain for machines described by AP 242 kinematics.

• Improved faceter to correct problem computing UV-space distance, which was causing some bad trimming paths. Now limiting tolerance on shells to global uncertainty, which corrects some faceting issues.

• Corrected problem where the wrong copy of a point was being used to connect multiple toolpaths.

Changes in release 9.39 (2012-02-24)

• Corrected issues AP-238 CC1 export function.

• Added support for extra geometry in AP242 kinematics models and updated Hermle 5-axis AC machine model with complete geometry for housing and other extra pieces.

Changes in release 9.35 (2011-08-29)

• Improved handling of wrap-around NURBS surfaces and STEP surfaces of revolution.

• Added new simplified DMG machine tool model created by KTH.

Changes in release 9.34 (2011-08-25)

• Rigid tapping on Fanuc and Haas now use G84/G80 blocks.

• RPI Haas style now uses whitespace for better readability.

• Custom code export style names are now case insensitive.

Changes in release 9.33 (2011-08-17)

• Faceting is now faster because it is done in multiple threads. Using a minimum of 2, and a maximum 4 based on the number of (virtual) processors in the system.

• Corrected bug where STEP data deletions were causing the system to crash.

• Removed extraneous refresh code that was slowing down editing of tool diameter, length, and radius values.

• Added internal notifications to stop background processing when the STEP-NC data is changing.

Changes in release 9.32 (2011-08-16)

• Major changes in the event loop processing which should keep things much more responsive while facetting. The faceter also now runs in a separate thread in the background.

• Faces are now added to the display as they get faceted. The axis direction arrows are now drawn using the stencil buffer and Z-buffer is preserved across multiple redraws.

• Fixed regression that prevented the Hurco machine from displaying.

• Now displaying coordinates in the main geometry window when picking faces. The coordinates and controls are still shown on the position palette.

Changes in release 9.31 (2011-08-15)

• Added "rpi-haas" code export style.

• Pick face to return actual pick point on face, and make Setup WCS or part space results work properly.

• Machine tool models on the machine tool menu are now grouped by type into virtual, milling, turning or robot categories.

• Improved graphics performance with special-case code for sphereical, toroidal, cylindrical, and conical_surface. This should result in faster and better faceting. Other facetting internal improvements.

• Fixed regression where missing probing tools were causing a crash in old data.

• Improved handling of degenerate trim edges (edges that are smaller than the global uncertainty of the context.) (Such edges really should never appear in the STEP data, but we do encounter them sometimes.)

Changes in release 9.30 (2011-07-14)

Changes in release 9.29 (2011-07-12)

• Added a new machine model for ABB IRB 6620 robot for testing other non-milling types of processes like welding, tape laying, or pick and place. When used for motion simulation, the tool is currently placed where the end effector would be.

Changes in release 9.28 (2011-07-12)

• Same as v9.29 above, but installer did not include robot geometry.

Changes in release 9.27 (2011-07-09)

• Reworked the position window to clarify what origin is used for the coordinates and to allow display in different units. The window now has a toolbar at the bottom. One of the toolbar button selects the origin as either the Part Space or the Setup WCS. Previously this was handled by the "Apply Setup Transform" checkbox. The other button sets the display to use the file units or force inch or mm.

• When picking a face, the position window now shows coordinates in Setup WCS if that option is selected. Previously it always showed the coordinates in Part Space.

• After changing a Setup WCS, the geometry display is now centered on the part and fixtures no longer turn on inadvertantly.

• The machine tool menu now has a "Show Extra Machine Geometry" button to turn on display of things like doors and cabinets that are not part of the motion axes. This is a per-machine setting, so you can turn it on for one while leaving it off for others. The Hurco and trunnion machine models both have extra geometry.

• Reorganized the machine tool menu on the toolbar. It is now called "Machine Tool" instead of "Motion". The "Collision" checking button is now on this menu rather than the top toolbar.

• Updated faceter with additional performance improvements.

• Removed spurious message when feeds updated for workingstep.

• Tool length adjustment algorithms updated to work when the tool is in inches but the ISO 13399 parameters are in mm and vice versa.

Changes in release 9.8 (2011-03-17)

• Added initial test code for computing toolpath sweep volumes, as "Show Sweep Volume" under the Simulate menu. Currently handles linear toolpath segments and does not yet take into account setup placement or tool axis changes.

• Internal geometry improvements, plus the Part Properties pane can now display a part as a working shell model for simulation testing. On the right-click popup menu for parts, use the "Show/Hide Shell Models" to toggle them on or off.

Changes in release 9.7 (2011-02-11)

• The Part Properties pane can now display a part as a voxel model. On the right-click popup menu for parts, use the "Show/Hide Voxel Models" to toggle them on or off.

• Improvements to the facetting of STEP geometry.

• Added a new wireframe mode for displaying the facetted model. Under the Views toolbar menu, select Wireframe or Shaded to switch between the two displays.

Changes in release 9.1 (2010-11-04)

• The trees and panes now keep better track of the workingstep, tool, or tolerance that you are looking at as you move from pane to pane. So picking a workingstep in the workplans tab, then moving to the tools or features tabs will show you that workingstep on the other tabs, and vice versa.

• The Feed/Speed editing pane now has more flexible options for highlighting toolpaths and executable. Instead of a single on/off button, there is now a menu where you can choose whether to draw toolpaths in bold, show workingsteps in a bold text, and whether to expand the workplan tree to see all affected workingsteps.

• Eliminated unneccessary reload of the workplan tree when editing feedrates.

Changes in release 9.0 (2010-10-26)

• The import shape for operation menu entries (as-is, to-be, delta, fixture) now show the operation after import. Previously, the display was going back to the first operation in the file.

Changes in release 8.30 (2010-03-11)

• Corrected menu entry for Import Workingstep Paths.

• Fixed bounding box computation in graphical display that was causing nothing to be shown for files that contained only toolpaths without any other geometry.

• Reorganized the various import operations on the workingstep context menu into a new "Import" submenu. This includes "Import Workpieces from STRL", "Import Workingstep from STRL", "Import Cross Section Data", "Replace Workingstep Paths", and the "Replace Workingstep" from MAX5 options.

Changes in release 8.25 (2010-02-16)

• Internal changes to "Read Cross Section Data" handling.

• Fixed handling of cross-section "name" parameter so that it stays in sync with the rest of the values.

• When the mouse is places over tools on the tools tab, a popup window indicates the total machining time and distance for that tool.

Changes in release 8.20 (2010-01-29)

• Using the checkboxes to choose elements of selectives now behaves like radio buttons. Only one is checked at a time.

• Adjusted the disabled color for grayed out list items in the tool display.

Changes in release 8.19 (2010-01-21)

• When workingsteps are disabled on the workplan tab, they are now displayed in a grayed out font on the tool tab.

• Removed the version number from the install directory name so that shortcuts pinned to the start menu or taskbar are not broken every time an updated version is installed. Also removed version number from the STEP-NC Machine start menu shortcut for the same reason.

Changes in release 8.18 (2010-01-15)

• Enhanced processing of Selectives so that the following operations that can apply to selective or workplan also work for selective
  • Insert Workingstep
  • Insert NC function
  • Insert Workplan

Changes in release 8.12 (2009-12-09)

• internal release

Changes in release 8.11 (2009-12-07)

• Updated machine simulator to support tool changers. When the tool is changed, the machine is moved to the changer location, switches the tool, and returns to the workpiece. The tool changer location is part of the machine definition. Similarly, the tool is withdrawn from the workpiece before the setup change is animated.

Changes in release 8.10 (2009-12-04)

• Initial support for tool change animation.

Changes in release 8.9 (2009-12-02)

• Added initial support for STRL links within workplans. Workingsteps that contain STRLs are now displayed as links.

---

Changes in release 7.40 (2009-09-24)

• Added "View | Workingstep Parameters" pane listing any higher level process parameters given for each workingstep. Currently covers tapping, multistep drilling, drilling, reaming, and boring as well as bottom, side, and freeform milling operations.

Changes in release 7.39 (2009-09-21)

• Added a "Replace Workingstep Paths" option to the pop-up menu on workingsteps. This will replace the toolpaths on the workingstep with ones from a workingstep with the same name in the specified file.

• The position window now displays units for the axis position, feedrate, and spindle values.

Changes in release 7.38 (2009-09-18)

• The tooltip windows in the workplan tree with time estimates for workplans and workingsteps are now updated when items are enabled and disabled, or when feedrates are changed.

• The main window now saves and restores the position of the split between the tree window and the geometry window between runs. It resets to the default split if the value gets unreasonable.

• Tool identifiers and tool numbers are now displayed separately on the tool tab. Both may be edited.

• Corrected an infinite loop when selecting tools with a tolerance on the tool tab.

• Added methods to the DLL cursor class for setting tool override.

Changes in release 7.37 (2009-09-16)

• Corrected initialization bug that was sometime preventing datums and tolerances from being displayed. Also changed face hilighting on the Part Properties pane so that only datum faces are shown when a datum is picked in the tree.

• Improved handling of workpiece display when looking at the Features tab. Now shows the to-be shape of the first associated workingstep.

Changes in release 7.36 (2009-09-15)

• Added support for Selective program elements. Generates code for the first enabled workingstep it happens to find.

• Corrected an issue with APT CL read of arcs in millimeters that was causing false errors.

Changes in release 7.35 (2009-09-14)

• Setting the As-Is or To-Be shapes on a workingstep does not modify the previous or next one if they already have shapes. Otherwise for simplicity, setting the as-is will also set the previous to-be, and setting the to-be will also set the following as-is shape.

• Added "To Selective"/"To Workplan" conversion options to the pop up menu on the machining program.

Changes in release 7.34 (2009-09-11)

• Change in the handling of default units when creating tolerances.

Changes in release 7.33 (2009-09-11)

• Code export now uses the digits of precision rather than a fixed epsilon to detect and suppress repeated coordinates on Fanuc, Siemens, Haas, Okuma, Heidenhain, and MDSI.

• Fanuc and Haas output now explicitly declare units using G20/G21

• Added support for Siemens G700/G710 unit declarations.

Changes in release 7.32 (2009-09-10)

• Corrected issue with workplan setup placement that was resulting in an error message "Could not find workpiece for setup"

• Improved tool axis interpolation in the graphics display animation to use Z axis as axis of rotation where possible when and we have a 180 degree rotation of the tool axis.

Changes in release 7.31 (2009-09-09)

• Corrected problem saving workingstep names containg quotes. Double quote appearing in XML attributes were not properly escaped, causing problems when read back in.

• Corrected gcode output of arc moves when a setup transformation is present. In all output styles, transformations were not applied properly to the Z axis of trimmed circles, and when outputting MDSI style lathe code they were being applied when they should not have been to the tool axis direction.

• Extended Siemens output for G2/G3 to emit A3/B3/C3 axis directions to specify the plane of the circle when not in the XY plane.

Changes in release 7.30 (2009-09-08)

• Transparency is now handled correctly when a workpiece is shared as the as-is and to-be shape of two different workingsteps.

• Corrected an error in the display of as-is/to-be shapes that could mistakenly hide a workpiece to when switching between steps if it is the as-is of one workingstep and the to-be in another.

• Extended DLL api with four new functions to the Cursor so that you can change the feed of every toolpath in a workingstep that uses the same technology and/or every toolpath in a project. Same for speed.

Changes in release 7.29 (2009-09-04)

• Improved the display of datums when multiple workpiece models are present. Datums are now shown on any as-is or to-be workpiece as well as on the Part Properties, and the show/hide checkboxes match the datums on the workpieces being shown.

• The enable/disable workingstep checkboxes on the "Workplans" tab are now initialized properly when reading a new file or inserting NC functions or other elements into the workplan.

• Enhanced workpiece import to more accurately determine a unit (English or Metric) for the imported part.

Changes in release 7.28 (2009-09-03)

• The graphics display now animates the tool movement when switching between workingsteps, including setup changes.

• Fixed the "Setup | Workpiece Properties" command under to work with MasterCAM block data.

Changes in release 7.27 (2009-09-02)

• In the code generation, transformations were applied in the wrong order when a setup placement on a workplan and a toolpath placement on a workingstep were both present in the data. The code was applying the toolpath transform to the setup one, rather than the other way around. This affected the Boxy data and should now be corrected.

• Fixed case where we were not transforming the toolaxis when the toolpath did not provide an axis curve, was just passing through the default 0,0,1 axis untransformed.

• Added "Program Comments" box to the CNC export dialog giving the ability to control the level of commenting in the output, with options for workingsteps, toolpaths, even points.

• Make Datum now clears the selection when the dialog is first brought up to avoid adding unintended faces to the datum, and also clears it after creating the datum so that the face color can be seen. Made similar changes to Make Surface Tolerance.

Changes in release 7.26 (2009-08-26)

• Added a new line on the tool tab to display the workpiece shape associated with each tool.

• Added ability to import and export tool shapes from the pop-up menu on the tool tab. Now shows an overwrite confirmation when importing on top of an existing tool shape. Also checked for exporting a tool shape when one does not exist.

• Changed the handling of setups to use the setup origin rather than a workpiece placement to specify the global machine transform.

• First attempts at applying setup transform during CNC code export.

Changes in release 7.25 (2009-08-26)

• Internal development checkpoint

Changes in release 7.24 (2009-08-21)

• The Feed/Speed window now shows feed per tooth when displaying all of the feeds for a workingstep or individual tool.

• Dialog prompting whether to save your changes now gives the option to cancel whatever action prompted the dialog (application close, open a new file, etc)

Changes in release 7.23 (2009-08-20)

• Toolbar on the workplans tab controls editing operations. A lock unlock button enables or disables editing. A second button turns the checkboxes on or off for selecting workingsteps.

• The Edit menu on the toolbar allows new worplans or NC functions to be added to the program and provides another way to edit the setup location.

• Program can be reordered by dragging and dropping workingsteps into their new location. Items can be moved up or down or deleted using buttons on the toolbar. See the docs for a full description at:
  • http://www.steptools.com/support/stepnc_docs/

• Improved behavior of "Import | Tool Shape" so that the tool to import the shape for is found by looking at the currently selected workingstep, or the tool selected on the tool properties page.

• Fixed problem where tools were not displaying after CL import. Also corrected geometry refresh problem after workpieces import.

• Improvements to numerous icons throughout the application.

Changes in release 7.22 (2009-08-19)

• Internal development checkpoint

Changes in release 7.21 (2009-08-18)

• Added an "Edit Setup Placement" option to the right-click context menu for workplans. This will add, remove, or modify the setup placement on any workplan.

Changes in release 7.16 (2009-08-10)

• Added different icon in the machine program tab to indicate workplans that have a setup associated with them.

• Corrected problem editing the project name on the program tab.

Changes in release 7.15 (2009-07-31)

• Corrected a crash when displaying feeds and speeds for nested workplans and some initialization problems could cause the Feed window to come up blank.

Changes in release 7.14 (2009-07-31)

• Corrected some problems that occurred up when the Feed window was toggled between shown and hidden. The feed window is now restored to the last known shown/hidden state on startup.

Changes in release 7.13 (2009-07-30)

• Feeds and Speeds can now be viewed and edited. Click on the "Feeds" toolbar button or select "View | Feeds and Speeds" to bring up the feed window. Using a dropdown menu at the top of the pane, you can see the feeds/speeds used by a particular tool, workingstep, or workplan. Values can be edited for the entire program or changes can be scoped to a particular tool or workingstep. We have also added a how-to article explaining feed speed editing at:
  • http://www.steptools.com/support/stepnc_docs/

• Changed the comments at program start for all known styles that support comments so that they include the STEP-NC source filename before the timestamp.

• Errors when saving, such as a write protected file, are now being properly reported to the user.

• The size of tool windows is restored between sessions when they are made smaller than original size. Previously, size was only restored when they were larger. Default sizes are still restored if the window is shrunk below 25% of the preferred size.

Changes in release 7.12 (2009-07-29)

• Internal development checkpoint

Changes in release 7.11 (2009-07-27)

• Added alternative Trunnion AC machine model that prefers to tilt the table in the negative A direction rather than the positive A.

• Added limited support for workplan setups.

• Corrected name editing in the workingstep tree so that it no longer includes the object ID in the initial text.

Changes in release 7.9 (2009-07-15)

• Internal development checkpoint

Changes in release 7.8 (2009-07-15)

• Internal development checkpoint

Changes in release 7.7 (2009-07-13)

• Fixed issue where the nudge increment for Adjust Mounting Location would end up as zero. The Trunion AC table is in meters, so nudges were a fraction of a meter and we were rounding to integer values.

Changes in release 7.6 (2009-07-10)

• Added ability to change the location of the workpiece on a machine tool model during simulation. The Adjust Mounting Location dialog on the Motion toolbar menu provides X, Y, and Z controls to shift the part from the center table default location. Values are in the units of the machine tool model.

Changes in release 7.5 (2009-07-02)

• Added Setup | Custom Tool Settings dialog so that users can specify flute counts or machine maximums that differ from the nominal values in the STEP-NC data. This information is only kept for the session and will be used to adjust feeds for different machine or tools.

• Added "Adjust feed based on actual tools" option to the CNC export dialog. This scales the feed to maintain constant chip load if the actual tool flute count difers from the planned one. The ".cnclog" file notes where and why each individual feed has been scaled.

Changes in release 7.4 (2009-06-29)

• Corrected user interface bug with Machine Parameters that was swapping the spindle feed and spindle power values.

Changes in release 7.3 (2009-06-29)

• Added an advisory message when changing the default unit.

• Updated Setup | Machine Parameter so that the expected units are displayed even if no values were previously set.

Changes in release 7.2 (2009-06-27)

• Added flute count to the parameters on the tool pane. Nominal values can now be edited via a right click popup for flute count, diameter, length and radius.

• Added Setup | Machine Parameter to set the expected machine capabilities for the program (Max fees, spindle, power, etc)

Changes in release 7.1 (2009-06-15)

• Modified the handling of datum colors so they do not conflict with the selected face color.

• The annotations on/off checkbox now controls tool annotations as well, simplified handling internally so that it is controlled by a separate scenegraph attribute.

Changes in release 7.0 (2009-06-12)

• Reworked license key handling so that machining partners can use a read-only free download version of the application to view STEP-NC data sets, simulate, and do basic CNC export. New data sets can be created in memory, but only development partners with an STEP-NC Machine license key can save them, use custom CNC interfaces, or other advanced operations.

• Changed main form initialization so that palettes are no longer restored before the main window is up. Previously they would appear while the splash screen was still present.

• Added Help | Latest News and Updates to link back to the website.

• Swapped the order of the origin and target parameters when calling the Align Workpieces by Datum or Face operations.

• Tools are now shown using the color information provided by the STEP file, rather than overriding it with the default gold.

• Fixed the "center on tool" operation so that it now works in all motion modes rather than just the virutal gantry.

• Added support for assembly data where the shape_rep_relation does not directly reference the two shape_reps of the NAUOs product definition. Instead there is another shape_rep_relationship between the two. This occurred in Alibre/Airbus data.

• Added initial simulator support to allow the workpiece to be moved around the table.

• Revised the placement dialog so that it is now resizable, which should make things clearer when dealing with long numbers. Also made the logic robust if called for a nonexistant workpiece, rawpiece, or fixture.

Changes in release 6.25 (2009-06-01)

• Fixed problem where general points were turning to the default color.

• Updated drawing of machine simulator to insure the WP is drawn first, then the tool, then the machine.

• Corrected problem with buffer switching where the clip region was getting retained when it should not have been.

• Fixed bounding boxes initialization/validation bug that was preventing AP238 models w/o workpieces from displaying.

• Graphics display now stays responsive during faceting operations. In this mode, an hourglass cursor is displayed, double buffering is disabled, the Windows message queue is periodically processed.

Changes in release 6.24 (2009-05-15)

Changes in release 6.23 (2009-05-12)

• Fixed regression in graphics panning behavior.

Changes in release 6.22 (2009-05-11)

• Added toolpath picking notification.

Changes in release 6.21 (2009-05-08)

• Internal improvements to facetting and interference checking.

Changes in release 6.19 (2009-05-01)

• Annotations are now displayed with presentation colors if given.

• When replacing a workpiece, any transform applied to the old one is added to the new one.

• Added option on the popup menu for workplans to go through all workingsteps and associate with the closest faces. The feature tab is also now refreshed properly after adding faces to a workingstep.

Changes in release 6.18 (2009-04-28)

• Initial implementation of interference checking for the machine simulator. Enable and disable using the "Collision" toolbar button. A machine tool model must be in use or else it is ignored.

• Improved shell integration so that double clicking on a stepnc file will now launch STEP-NC Machine.

• Added a "Browse Simple" option to the p28view utility that disables usedin information, popup display of attributes, highlighting of the current object, and other Javascript features for better browser performance on large files.

• Changed p28view so it no longer self-registers its file type in HKEY_CURRENT_USER every run because this causes problems with outdated paths shadowing the proper paths in HKEY_LOCAL_MACHINE. Updated the installer to clear those old paths, so things should work better for anyone who was experiencing that problem.

• Fixed graphics regression where tool movement was out of sync with the machine simulation.

Changes in release 6.17 (2009-04-21)

• Extended geometry display of workpieces and machine tool models to show the presentation information found in the underlying STEP data.

Changes in release 6.16 (2009-04-14)

• Added G90 and clear work offset to Okuma startup. Added G56 tool offset in Z to Okuma tool changes.

Changes in release 6.15 (2009-04-10)

• General Point Sets are now displayed on their associated product geometry. Datum targets are also now displayed with both Workplan and Part Property tabs.

• Extended Okuma CNC output to use G15 to specify work offset and G20/G21 to describe whether inch/mm units are used.

• Extended CNC output for all machines with a descriptive comment before each tool change listing the tool parameters in the STEP-NC data (length, diameter, etc).

• Added Setup | Placement | Align by faces option to move workpieces around by selecting two sets of three faces to align.

• Added Setup | Placement | Align by datums option to move workpieces around by selecting two sets of three datums to align.

• Added Drag And Drop reordering to the face selection lists.

• Updated toolbars and the main window menu strip to support "click through" when the window does not have focus. Previously, a toolbar button or menu needed two clicks, once to give focus to the owning window and a second time to activate the button/menu.

Changes in release 6.14 (2009-04-07)

• The add/remove face and datum creation dialogs no longer lose focus when selecting geometry in the view window. Added a toolbar to both dialogs to simplify moving between pick and rotate/pan modes.

• Updated the Define Surface Texture and Define Tolerance Dialogs with the improved interface for selecting faces, and reworked to create with multiple faces rather than having to add faces afterwards. Added a toolbar to simplify moving between pick and rotate/pan.

• Set target cpu type of the .NET assembly to be x86 to force the COM components to be run on WOW64 on XP 64. Otherwise, COM can not find the registration for the factory and throws error 80040154. Likely also the case for Vista 64.

Changes in release 6.13 (2009-04-03)

• Improved the add/remove face user interface so that deletion is clearer and selecting faces in the geometry viewer is reflected in the list. Also reorganized the code so this interface can be used elsewhere, such as in tolerance/datum creation.

• Reworked Add Datum interface to allow datums with multiple faces to be created rather than having to add faces afterwards. Now supports datums with labels other than ABC.

• The workpiece properties dialog now displays and sets material for both the workpiece and rawpiece.

Changes in release 6.12 (2009-03-25)

• Improvements to handling datums. Datum deletion now works properly. When creating datums, least material condition is now supported. On the part property pane, selecting a datum or datum target will now switch the geometry display to the relevant part.

• Corrects geometry refresh issue.

Changes in release 6.11 (2009-03-20)

• Fixed inadvertant removal of AP203e2 dimension and presentation information when importing workpieces.

Changes in release 6.10 (2009-03-20)

• Datums and datum targets are now displayed on the Part Properties tab along with the tolerances for each workpiece. Faces can be added or removed using the context menu. Deleting datums using the context menu is enabled but does not work correctly at the moment

• Presentation and drafting annotations are now properly categorized into application objects and saved in the STEP-NC file.

• Toolpath rendering is now deferred until first access which will improve load speed.

• Bounding boxes now reset when switching between machine models.

• Corrected issues with tools disappearing when switching back and forth between the parts property tab.

• The facetting tolerances are now adjusted for better quality on small parts without slowing larger parts.

Changes in release 6.9 (2009-03-12)

• Faceting of STEP models is now done the first time they are drawn rather than at load time. This should result in faster load times in files with many different models, but occasional pauses when showing new models.

• Fixed issue where tool was sometimes rendered far too high a resolution resulting in slow behavior.

• Fixed issue where moving parts of machine tool models were unpickable.

• Fixed crash when processing (illegal) toolpath curves consisting of a single point.

Changes in release 6.8 (2009-03-10)

• Various internal changes stemming from a scene graph reorganization and changes in the color/transparency state handling.

• Corrected odd message overflow in the status line when canceling the face/edge/part selection.

Changes in release 6.7 (2009-03-09)

• Added support for tool reference direction added by the AP238 technical corrigendum. The geometric display will orient the tool properly. The GoToXYZ_IJK_REF_ABC() function has been added to the DLL API to create this type of data.

• Inproved geometry display of trimmed b-spline curves and made the ellipse processing more tolerant of marginal data.

• Corrected exception at startup time if the machine model directory was not present.

• Many context and other data creation fixes prompted by external testing as well as internal testing with ap238check. Updated the cross section area parameters use a 7D geometric representation context instead of a generic one. Changed the CUTTER CONTACT and CUTTER LOCATION TRAJECTORY surface_normal to use unitless 3D context like the tool axis instead of units.

• Changed the following properties to use a geometric unit context:

Changes in release 3.59 (2007-10-26)

• Corrected some issues with probing start points.

• Updated DMIS output so that both "dmis" and "dmis-manual" declare features and tolerances with the features, added GOTO moves between the PTMEAS commands in the feature measurement blocks. Added additional probe declarations and other setup boilerplate at the start of the program. Generating manual mode initial declarations for all datums on the workpiece. Also corrected placement of Cylinder features.

• Changed DMIS output logic so that it emits moves for any workplan that contain any nested probes. Workplans that do not contain any probing are ignored.

Changes in release 3.58 (2007-10-19)

Changes in release 3.56 (2007-10-15)

• Changed the DMIS manual output so that we measure known features directly (PLANE,CYLNDR) rather than create many point features and construct from them. This simplifies the DMIS tremendously. We still define point features if the STEP-NC feature is based on an geometry type that does not map to a DMIS feature.

Changes in release 3.9 (2007-01-16)

• Selecting a workplan now displays all toolpaths within the plan. For performance reasons, this has been disabled for the main plan but may be enabled at a later date.

• The probe maker now offers to create a position tolerance. Also remembers preferred probe direction between calls.

Changes in release 3.8 (2007-01-12)

• Fixed resize of backplot buttons and speed slider in left column and positioning of the coordinates display in the model window.

• Explorer now goes to the first workingstep with a toolpath rather than looking for one with multiple toolpaths. This means that a probing operation will be shown if present.

• Added the current pick/pan/rotate status to the toolbar.

• Changed the cursors used for picking bodies, faces, and edges to be less goofy looking (was a stickman, smiley face, and an E).

Changes in release 3.4 (2006-12-29)

• Added View | Entity ID for Pick menu option to display pick results.

• Expanded coordinate box to accommodate larger numbers and greater precision.

• Added display support in the workplan tree for more NC Functions (return home, program stop, and optional stop)

Changes in release 3.0 (2006-12-18)

• Added a display pane for Probing operations as well as coloring of features on the part (red/yellow/green) depending on the results of probing returned from the CNC. The model view has checkboxes to display datum faces if present in the part. First demonstrated at the Hershey ISP meeting and since improved.

• Corrected the handling of the "most recently used" file list on the File menu.

• Reworked the internals of the STEPNCExplorer Active X control to remove any remaining references to the StixCOM package. The tool now gets all data directly from the STEPNC DLL. The COM signature of the tool has changed as a result, so the OCX is now version 3 rather than 2.
