generative modeling for Rhino
Fernando Garcia raised the question on this post (http://www.grasshopper3d.com/profiles/blogs/grasshopper-to-revit ) about means to exchange a waffled representation to Revit from Grasshopper.
As the panels are in vertical and horizontal planes, they can be represented as walls and slabs. I'm not sure on the units of the pieces (I assume inches was most logical) but I've been testing this transfer this morning via IFC using the Geometry gym addons.
Most pieces work fine, although the Revit extrusion fails for some walls. I've been testing changes to rhino document tolerance as Revit will have particular planar requirements. Adding the perimeter curves to the revit document they appear ok.
You can import the IFC2x3 file using the native revit importer and get reference objects, but this is not really too different from importing DWG etc.
Files are attached if anyone wants to try, download latest builds from http://www.geometrygym.com/downloads
I meant to add, here's the IFC and GH file if you're happy with the native Revit import of IFC.
Well, you should be able to use the same IFC files to import into Archicad. I don't have access to this software at the moment, so great to hear feedback if it works or if you see problems.
