10/31/2023 0 Comments Revit to cad![]() ![]() The shell for our sample use case comes from the Tulip armchair, by Eero Saarinen. Transition from imported CAD to native Revit geometry. If you ever wanted to "shrink wrap" something in Revit, you're in the right place. In the Revit family editor, we will import the 3D geometry in DWG format and use it as a reference for tracing profiles for the final shell. ![]() The shell of an injection-molded chair is the perfect application for this workflow. ![]() Finally, there is a step-by-step guide, followed by few tips and side notes. Then we'll go over how to identify and draw profiles that follow the imported geometry. We'll begin with a brief introduction to forms in Revit adaptive families. This post introduces a workflow that lets you do just that in order to reproduce 3D CAD geometry natively in Revit. Complex, smooth surfaces can actually be modelled relatively easily as a form in an adaptive family. Then you populated your model with dozens of those chairs, and thought, "Hmmm, my model is very slow."Īnd then you spent a day building what ends up being a 3MB family with 8 swept blends and 11 voids that looks "kind-of-sort-of ok, just don't zoom in too much." You know the type. Have you ever found yourself looking at the jagged, tessellated 3D CAD import of a chair in a Revit model and thought, "Hmm, that's a lot of polygons." A complete step-by-step guide for reproducing 3D CAD geometry natively in Revit using forms and adaptive families. ![]()
