Is it in any way possible to get the following geometry as a void in Revit? I have managed to get a rectangular void by intersecting bounding boxes and x point adaptive voids, but this would certainly be more nifty.
Not sure exactly what you are after, but you can make void forms directly in the Massing environment using Form.ByLoftCrossSections.
is that what you are looking for?
Not exactly no. The overarching intend was to import a void of any form into Revit, but according to this link it will not be anytime soon?
