Service Pack One updates Version 18 of 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.
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.
STEP applications support the latest SMRL v8 definitions from AP242e2 and AP238e2 DIS ballots as well as improved matching for complex instance cases seen in practice. This includes the latest tolerance and PMI definitions, additive manufacturing setup, tessellated models, and 3D point cloud definitions. The STEP Explorer views the new semantic tolerances while new APIs create and read them.
The STEP Meshing library now supports offset surfaces, negative slope on cones, and better handles open loops and singularities in UV space. There are many API improvements for fine grain control of the faceting and access to the surface, uv trim polygon and solver. The mesh library also has code for writing STEP assemblies in the Additive manufacturing file format (AMF) and the 3D Manufacturing Format (3MF). Additional AMF/3MF support has been built into the ROSE Math library.
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.
