Common Mistakes to Avoid
Converter failures usually come from mismatching tool capabilities to output expectations and from underestimating cleanup and integration effort.
Assuming one CAD converter will produce editable, clean geometry for every source file
Onshape converts into editable Part Studios, but conversion fidelity can still degrade on complex or highly tessellated data and often requires cleanup. FreeCAD’s parametric and Shape-based editing helps repair inconsistent topology, but messy files commonly need manual topology and tolerance cleanup.
Choosing a web-viewing tool when parametric downstream edits are required
Autodesk A360 / ACC Platform is optimized for Forge derivatives that support browser viewing and inspection rather than full authoring edits. For editable downstream work, Onshape and PTC Creo provide conversion into editable modeling environments instead.
Ignoring assembly hierarchy and metadata requirements for downstream systems
