I was reading a post on the AUGI forum for a user who wants to tag all his/her toposurfaces with their Surface and Projected Area, both parameters in the objects’ properties. I had no problem pulling the values of the toposurfaces.
Since toposurfaces cannot be tagged at all, I was thinking of placing a family instance at the centroid of each toposurface and pushing the values of the toposurface into that object, then tagging it. I’ve created a working prototype of this that worked as I expected when I limited it to one toposurface. However, when I feed in all the toposurfaces, it placed the family instance in strange places off the toposurfaces, definitely not the centroid. Can you find the problem? Can you think of a better way to do this?
