If I'm linking in a model with bearing walls into my structural model, I can't attach anything to them. I can't put a wall footing under it, I can't attach a beam to it. All I can do is have it displayed. I can't put a thickened slab edge onto a slab or floor thats from the linked in model. Can we change that? Let me work with those common items between the models so that we don't need to do the work twice.
