I have created my first door/window assembly and am having a few problems with it. While the 2 individual components in the assembly (a previously created door style, and a previously created window style) seem to be anchored to the wall (meaning that when I erase the wall, it erases the components within it), the two components do not seem to be anchored to each other. When I select either one of them to erase the assembly, it only selects that one component and not the whole assembly, nor does it fix the wall it is inserted in. Is there some way to have both components of the assembly linked to each other so that if I select either of them to erase, it captures the entire assembly? Is there some setting I need to change so that when I erase the components of the assembly, it fixes the wall automatically.
