Using FreeCAD v0.17 (7180) and the latest StepUp, I noticed my FreeCAD project is modified when I Export the model in STEP format. Below is a before and after of the FreeCAD “project” window:
My assumption would be that exporting a model would not modify the FreeCAD project structure, but it seems to.
I narrowed this down to the STEP export by refusing to replace existing STEP and/or WRL. It’s only when I export the STEP format that this seems to happen.
Is there any way to prevent this?
