Autodesk went all in on Microsoft platforms some years ago. AutoCAD and 3DSMax are Direct3D-only on Windows. Their software on Mac and iOS devices uses OpenGL for now, but I think Autodesk will likely switch the back end out for Metal, given Apple's sterling reputation for OpenGL support. /s

Point being that OpenGL exists mainly to support old CAD apps. Actively maintained current apps will switch to Vulkan, or whatever API provides the best benefit on the target platform.
