I have a few questions actually, and would really appreciate any help in regards to any of them. I have completed my model in sketchup (saved as osm file). I have added all the exterior windows, and now I am trying to do the surface intersecting and matching. Does it make a difference if you do the surface matching before or after adding windows? Also since the sketchup plugin that performs surface intersection/matching creates errors (many spaces turn white), I have downloaded the Surface Matching Measure in Open Studio (1.4.0), which worked fine for me when I tested it earlier on the first few floors. However now after completing the entire building, the apply measure is not working. When I ran it awhile ago it only took a matter of seconds, but now it either continues to run forever or gives me an error. I can't figure out what is going wrong now.
