I too am a recovering AutoCad user that has finally returned to Vectorworks 12.5 but am in a position where I have to share files with the AC crowd. When I try to export my mcd. drawings which are rather large to begin with ( approx. 17mgs.) they end up being more like 64 mgs. when I'm finished. I tried converting everything to group and then ungrouping everything and deleting all the symbol, and resources. I purged all unused layers, symbols, classes, resources, etc. and end up with an enormous file (approx. 53mgs. ) that when exported to dwg ends up being more like 107 mgs.!!!
I really need to get a handle on this as soon as possible cause the boss's patience is running thin.
Any help would be greatly appreciated.
Thanks,
Mike
