The paraview supports *.stl, *.obj fileformat. Is there some plugin can import CAD model, such as CATIA, PROE, SolidWorks file or Standard format like IGES, STEP? And is there some plugin can read FBX file?
The main issue is that we need to rely on external tools to read these formats:
- a BRep to mesh tesselator for the CAD formats (e.g. OpenCASCADE for IGES/STEP)
- Autodesk FBX SDK for FBX format
It looks that there are some plugins available on github but none are maintained by Kitware.
You can also use external software like FreeCAD to read CAD formats and export VTK files.
There is now support for .step and .iges in ParaView 5.12.0 binary release
Is it capable of writing iges and step or only reading ?
Only reading; there are no tools in ParaView to create or modify parametric B-Rep models from the discrete geometry used for rendering. Until there are, a writer would have no purpose since it could only write a copy of the original file.
