The thing is that Altium requires STEP files. Exporting STEP files are almost always paid software tools (ie. Fusion 360, Creo, Solidworks, etc.)
The only free tool that I found is FreeCad. If you are like me, and doing 3D is a rare occasion, then it may be fine.
I had partial success modifying a STEP model. But, if it just 'splitting' a combined model into two parts, then no problem.
