I was created an assembly from the bottom up from subassemblies. Everything was running smoothly, then I modified a subassembly and when I rebuilt entire assembly the model was flipped over and the roof of the structure was where the floor was. (If it was a person, the top of their head is now where the soles of their shoes used to be.)
Basically it was rotated and now the shadow is now on the wrong side.
I have googled for an answer but I can't find something quick and easy.(Doesn't everyone have that problem? :-D :-D)
I just want to reorient the assembly model in the space and not need to make reference planes, ground planes, etc...
