I have 3 models here. Basically the same thing in 3 different scales. After upload I am noticing 2 interior walls that don't need to be there. I have run these models through the Nettfab cloud repair service with no success in keeping those walls out of the model. Could someone remove these interior walls or advise me how to do it? I tend to lean toward the cloud repair service since Nettfab itself is still very foreign to me outside of using it to view my designs after they have been run through the cloud service. I am using Sketchup 14 and would like the fixed files to be in the same format as these are not yet completed. I uploaded early to check wall thickness and to get an approximate price for each.
