Hello. We are an A/E firm utilizing Architecture, MEP and Civil 3D 2009. We have 3 office locations and are connected so that we are working LIVE by utilizing mirroring software. Currently, we are experiencing trememdously slowness with AutoCAD when more than 1 office is connected to a project with the Project Navigator. I'm sure that other companies are utilizing the same software and working between offices on the same files. So, I'm wondering if anyone may have some suggestions as to what type of connection we should have... T1, point-to-point, etc. Any advice is greatly appreciated. Jane...
