FreeCAD

FreeCAD matters because it provides a practical open mechanical ecosystem around OCCT and STEP-oriented workflows. It is relevant wherever EngineeringOS needs mechanical context, assemblies, or geometry-adjacent interoperability.

How EngineeringOS Uses It

EngineeringOS should treat FreeCAD as a mechanical workbench and exchange reference. Import, export, and plugin boundaries with FreeCAD can extend the semantic core into mechanical outputs without turning EngineeringOS into a mechanical CAD replacement project.

Boundary

FreeCAD is a downstream mechanical environment, not the semantic center. EngineeringOS should use it as a back end and compatibility path, not as an architectural template for the whole platform.
