What the hell is a read-only dimension?
I'm trying to use an equation in a top level assembly to tie together a dimension in one subassembly with an equivalent dimension in another subassembly.
It tells me I can't do it because the dimension is read only.
On other occasions it won't even let me pick one of the dimensions to be driven by the equation, saying "Cannot select a dimension from another model to be driven by an equation in the current model". I've successfully done this within this top level assembly already, so why is it now giving me this error?
