Save shape STEP with color
Hey, are there any plans to support saving of a shape in STEP format with a provided color?
I am no expert in OCCT, but I think you have to create a doc with the shape, use the XCAFDoc_DocumentTool_ColorTool and create the STEP file with STEPCAFControl_Writer instead of STEPControl_Writer.
As far as I can tell, there are already bindings for STEPCAFControl_Reader in bitbybit-dev-occt, but not for STEPCAFControl_Writer.
Hey @denblock,
STEP Colors indeed are not supported at the moment - both during import and export. I'm preoccupied with some other stuff, but I have some beginnings of assembly implementation where I thought colors could come into play. It would provide more "natural" way to assign colors to different shapes within assembly. The problem is that assembly support is quite a big feature and it sits stacked due to time limitations. Whereas simple color support might be a bit easier to implement... I do not have a timeline for this, but I'll let you know when I analyse this more.
Hi @denblock,
The latest release candidate introduces a wide range of new assembly features. I’m happy to share that it’s now possible to save STEP files while preserving colors from Bitbybit.
