@pafurijaz Found it https://dsculptor.gumroad.com/l/exportiges !
But my goal is not to export to CAD, but to USD. Even with b3d 3.6alpha I still see no way to properly export SubD to USD. All my tests either create an xform without data or tesselate to a polyMesh on export.
@pafurijaz Final goal would be to have USD with two payload variants: one for smooth rendering using SubD and dispacement shaders, the other for current generation realtime rendering (AR Quick Look) with midRes polyMeshes and normal/bump maps.
To be used in @configxr, my open source project for AR product configuration.
