Version 18 Service Pack One Released!

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.

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.
