I am quite new to sketchup, I am hoping someone can help me out. I have imported an IFC file and want to Push/pull a surface to adjust the heights. However, the surface consists of many faces and I cannot join them. Is there a way I can do this so that I get just one surface for each building. (Image attached)
This worked. Thanks!
Is the surface flat? If so, you could erase those hidden edges before running Push/Pull. If the surface is flat you really should get rid of those edges anyway.
