What's the best way to edit OpenSim's .vtp mesh files?

What would be the best (hopefully free) way to go about editing the opensim .vtp meshes? I need to just trim the femur and tibia to keep just proximal femur and distal tibia, so pretty simple edits, then with OpenSim Creator I can splice these together with a fixed joint. I see a lot of options, tried one but it didn't handle this format.

VTP files are kind of annoying to use. I believe the reason the project standardized on them was because earlier editions of OpenSim used VTK.

The trick I use is to re-export the mesh file as an OBJ or STL from OpenSim Creator. You can do this by:

• Right-clicking the mesh in OSC
• Export > With Respect To > (select the frame it's already attached to)
• 90 % of the reason why the export feature was added was entirely to try and get editable mesh data out of VTPs 😉
