After I draw the walls and hit build foundation, when I view in camera view the foundation is there, but there is a gap between it and the walls. How do I fix this problem? I have just started using CX7 Sorry, not where I can send a picture today. The wall is a standard sip, air space, and brick veneer. The foundation is 4' tall concrete block faced with brick veneer on a 8" x 16" footing. When I look at the plan in orthographic full overview every thing looks good except there is about a 2" gap between the foundation and the wall all the way around. You can see through to the crawl space. I have checked the wall specs., type definition, etc. I found an article in the knowledge base on resolving a gap between floors but it did not help this. I know it is probably something easy I am missing.
