I see that ArchiCAD is spending lots of time "Calculating Split Polygons"; does this indicate I have some models which are somehow "split"? , or is everything split in a way?
Does it indicate a problem with one of my models?, if so, how can I troubleshoot it?
No, there is no problem with your file.
