Sorry, I'm a pretty occasional user. My name is my username. I have Home Designer 10 (I think). I always re-save any Sketchup files as version 7 before importing. I'm just confused as to what makes some appear weird after importation. I understand Home Designer doesn't have the ability to "fix" bad symbols though how do I know what's actually wrong with them when they appear perfectly fine in Sketchup? How do I fix what looks like a perfect 3D model? Cheers.
