I had imported the Revit model to IES. In IES, level1 and level2 were clear. But when I checked level3, I found that there were rooms of level2 shown as well, and I could not 'tidy' them.
I went back to Revit arch, the wall settings of 3 levels were all same. Floors and ceilings were also correctly set.
I don't know how to deal with it..anyone can help me to solve this problem?? Thanks!
