NICE tutorial

Every interesting demo on IES VE.

Hello, I imported my gbXML file into IESVE and I have the following issues: 1. 2 spaces were not imported. 2. Some spaces do not have a floor underside. 3. Part of a curved wall is missing. 4. The model seems confusing as it used a combination of ceilings and floor to represent the upper floor. I don't have any experience with IESVE. I'm a student in Electrical Engineering trying to analyze energy consumption in a building. I would be grateful if you could help me.
