This issue came up yesterday, a reasonable straight request…”I have built this surface in “PRODUCT”…….. (insert Rhino or AutoCAD). Can I rebuild it in Vasari or Revit as a water tight closed object, so I can do that I do that create floors by mass thingy?”
So here goes; this is what I was able to achieve. It should be noted that this may not work for all surfaces, but it certainly worked for this form. I started by creating a new mass family in Vasari / Revit. Next I imported the Rhino surface.
I then choose divide surface & picked the imported Rhino surface, you may need to tab select until you get to the surface, but you will be able to subdivide the surface.
The UV grid would act as a template to trace. Then, under Surface Representation I enabled Nodes.
Using model lines > spline through points, I was able snap to the nodes to generate a profile following the surface.
I repeated this a couple of times to build a series of closed profiles.
Next I deleted the imported surface. I half expected everything to disappear, but fortunately I the model lines remained! I then converted these lines to reference lines & closed the gap at the base with another reference line.
Then selected all the model lines & chose create form to build the form.
As I suggested, it should work for simple forms & is a relatively quick way to rebuild in Revit or Vasari….but don’t assume it will work for all.
