XVL Work Instruction Suite
Wow, this is awesome: https://www.lattice3d.com/products/XVL-suite-bundles/work-instruction-suite
Unfortunately useless, as it only runs on Windows:)
But I will study it more and think about how we can implement a similar solution using available open source tools. We can do this, the question is how much we can automate the process. Since FreeCAD and Blender are fully Python scriptable, such automation can be readily integrated if we have a Python programmer.
