I'm working on finding out how to apply a second floor onto our houses for my teacher. We can desigen the floor plans but were wondering if there is a way to put them together to create our second floor?
the native way in ACA is to use the project navigator, essentially a tool to organise X-ref's (seperate drawigs) for different views of your model. So each floor would be modelled in a seperate file.
I think that's overkill for residential but until Adesk catches on to a single file approach or you want to follow one of the maverics like me who have customised to do it in one file you will need to get into the help.
