Version 19 Software Released

In 1994, the first STEP CAD interfaces changed how companies did business by exchanging full-fidelity brep solid geometry. In 2021, the next generation of STEP is producing intelligent product models with full associativity, which will again open new opportunities for business.

Our STEP Tools development solutions have powered commercial CAD, analysis, and visualization systems since the very start of this journey. Our latest release has the very latest for sematic tolerances, new geometry, STEP-NC manufacturing, and building information models, packaged in the fastest and most reliable libraries for making, using, and manipulating STEP, STEP-NC, IFC, and CIS/2.

Version 19 of ST-Developer adds:

  • Latest STEP models, with 400 new definitions for semantic tolerances, additive setup, tesselated models and point cloud data, as well as UUIDs, references, and UTF-8 strings introduced by the third edition of the STEP file format.
  • Latest IFC models, with IFC4x3 definitions for with continued automatic migration of older data through IFC4 and IFC 2x3.
  • Modernized OpenGL graphics for very large STEP and IFC product models. View models an order of magnitude larger than the last release, up to multi-gigabyte sizes, with responsive motion, quick picking, transparency, and traceability across multiple reused parts.
  • Faster simpler meshing, particularly for splines. More types of geometry, offset surfaces, IFC4 trimmed breps and all swept profile types.
  • New assembly and shape indexes. Simpler and easier to find extensions for tolerance, assemblies, dates, units, placements, and measures.
  • New Apple M1 platform, Visual Studio 2019, GCC-7 on Linux, and the latest Xcode environment on Mac.

The release notes for v19 have much more information about the libraries and new features! Our knowledge of these standards is unmatched across the industry. Whatever your goal, we provide the tools that you can rely on to reach it.

One Million Unique Parts Machined

STEP is a standard for product model data and IFC is a standard for building model data. Both are very widely supported by CAD, CAM and BIM systems.

STEP-NC AP238 used to make 1,000,000 parts in 2019

  • Argument won — STEP-NC is the machine control data for future aerospace.
  • Boeing uses STEP-NC to machine parts for all its major airframes both single ailse and double aisle — even for satellites.
  • Engineer who did the work promoted to Technical Fellow.
  • Soon FAA is likely to want STEP-NC documentation for every machined part on an aircraft.

STEP AP242 Edition 2 is finished

  • Every CAD system has an interface to read and write STEP.
  • Edition 2 enables automatic measurement for on-machine CNC, and off-machine CMM.
  • Edition 2 enables kinematics for digital twin manufacturing.
  • STEP has the biggest and most widely tested information model for engineering.

IFC very popular for building models

STEP reduces the cost of manufacturing by allowing products, processes and machines to be assembled digitally for testing before delivery. IFC does the same for building construction.

  • IFC technical meetings include thousands of attendees.
  • IFC translators are being upgraded for latest STEP geometry.
  • Building projects are producting very large multi-gigabyte IFC models.
  • Every BIM system has an interface to read and write IFC.

If you own a CAD, CAM or BIM system, then we can help you extend and maintain your STEP and IFC interfaces with the latest libraries and visualization systems. Our librares are used by many of the leading CAD vendors, including NX and Autodesk, because they are the fastest and most reliable.

If your are a leader in manufacturing or construction, then we can help you use STEP and IFC to make better products. We are leading the deployment of 3D product models in manufacturing automation. There are many savings including a reduction in the cost of tooling of 15% or more.

Enabling Closed-Loop Machining

August 29, 2019 — This short walkthrough shows a digital thread model in the STEP-NC Explorer. You will see geometry, tolerances, and process, simulate material removal, and discover how to get feed/speed, position, and calculated tool engagement cross-section information at any point in the machining process.

This information can close the loop with model-based machining and enable new applications for tool life and tool wear prediction, calculation of forces and heat, and many other possibilities.

Build it Here, Build it Now, Build it Right with the Digital Thread

On July 12, 2017, a team led by STEP Tools stretched the digital thread farther than ever before - from design, through manufacture, and into five axis measurement.

The Digital Thread is a vision for manufacturing that opens many new opportunities. You can build it here because the thread is interoperable. You can build it now because the models in the thread enables full safety checking. Watch the video to see how to build it right.

On machine measurement will replace less responsive approaches because the integrated tolerances, machine feedback and linked evaluation give results before a part leaves the machine.

We challenge the machining industry to start delivering these benefits. At IMTS and JIMTOF 2018 we will supply test parts and confidential evaluation of the measurement results. We want you to demonstrate that you too can build it here, build it now and build it right.
