I have encountered a problem when I want to extract my corridor solids. I have a corridor that consists of an asphalt shape with foundation shapes underneath. Next to the shapes there are berms and ditches that are represented with links. You can see the subassembly in the attachment. Now when I want to extract my corridor solids only the links and foundation shapes are extracted. The asphalt shapes are not extracted except when there are no links present then the asphalt got extracted as well.
Please help, its driving me crazy 😉
