Our client just switch from designing the site plans and building layouts in ACAD to designing in Revit. Cool; I like Revit. But his CAD monkeys are having a hard time providing us something with which we can design in C3d. Likewise, our client will need to take our DWGs (converted from C3d to ACAD) and make use of them in Revit. What can we expect? How painless is this?
I'll also post this in the Revit forum.
