I have a few events coming up that are using a Stageline 320. Its a common mobile roof system used in America frequently. I have a DWG file of the stage from the manufacturer. When I import the dwg into Wyg it runs extremely slow and is basically un workable. Assuming because it has too many points. I've read a lot of posts and am still a little confused as to what I need to do to design accurately with the Stageline in Wyg. Id appreciate any links or advice. Thank you.
