Update 2021-01-22: We have posted Preview #4 that can now turn individual faces on/off, corrects a display problem that occasionally occured when selecting solids, and now properly handles filenames with the full range of international characters.
Update 2021-01-08: We have posted Preview #3 that now has the ability to select parts and faces, display their identity in the file, and turn solids on/off.
Update 2020-12-14: We have posted Preview #2 that now displays AP242 annotations and other edge data.
Please try our new large model viewer. The viewer has been optimized to display very large product models. The more CPU's and GPU's on your box, the faster it should operate.
You may download a viewer at no charge. We are actively developing the code and look forward to your comments. We are particularly interested in ideas for making the viewer more useful for digital twinning at your enterprise.

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
STEP AP242 Edition 2 is finished
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.
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.
October 28, 2019 — Service Pack One updates the STEP Tools development stack with the latest definitions for working with AP242e2, AP238e2, and IFC 4x2, plus improvements to the underlying libraries. The release notes have full details.
STEP applications now have the latest SMRL v8 definitions from AP242e2 and AP238e2 DIS ballots, including the latest semantic tolerance and PMI definitions with new APIs to create and read them, plus code for writing STEP assemblies in the Additive manufacturing file format (AMF) and the 3D Manufacturing Format (3MF).
IFC BIM applications now support the latest IFC4x2, updated with several dozen new definitions for bridge construction and infrastructure alignment, along with improved automatic migration support for previous IFC versions, IFC meshing, and IFC-specific checking and browsing.
The ST-Developer is core technology for STEP CAD applications, particularly with the Second Edition of AP242, BIM applications for IFC and CIS/2, and Digital Thread Manufacturing applications using STEP-NC, MTConnect, and QIF.
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.
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.
STEP-based solutions for CAD or engineering analysis, bill-of-materials, or supply chain integration: CAD shape, tolerances, assemblies, import or export, desktop or web visualization.
IFC-based solutions for BIM systems: translation, bill-of-materials applications, and visualization.
Connect product design, manufacturing, and inspection with a digital twin, built in real-time while machining with our new 3D model-based simulator. View from any mobile device, automate metrology, collaborate with supply chain, and real-time optimization.
