STEP 3D to Open CASCADE

Version : 2023.4
Update date : 2023-09-29

- Enables accurate and convenient 3D CAD data transfer from STEP to OpenCascade.
- Provides a function to be called (C++) in an OpenCascade based application.
- Converts CAD files: *.stp, *.step et *.stpZ
- Gets solid, surfacic, wireframe models, assemblies of them.
- Access to graphic attributes (colors, layers, visibility) and names of items.

By downloading this product, you will install CrossManager, in order to test easily our OpenCASCADE converters. After your tests, we will give you access to our import libraries for OpenCASCADE.

Version

(STEP: AP203 (E1, E2), AP209, AP214 (up to E3), AP242 (up to E3), AP238 (.stpnc)) (Open CASCADE: 6.2.0 to 7.6.0)
