I use Autoturn for my vehicle simulations for years now. Only 2d but we have the pro so I should be able to make 3d simulations too.
The video below shows how to change a Revit model into a Autoturn compatible Autocad model.

Only one little problem.... We make parkinggarages and this workflow only works for Toposurfaces.
How do I change a Revitfloor into a PolygonMesh or PolyfaceMesh? Second floor, ramp and Thirdfloor in one. And they have to be triangles
Kind regards Ron Wubbena
