I just purchased the 2017 version of Home Designer. When downloading from the online 3D library, would I only download the 2017 files? For example, the Rec Room and Games 3D models has a few versions. Would I get everything from that category if I only download the 2017 files? Or would I need to download all of the previous versions as well? Also, are the previous versions compatible with the 2017 software?
