This would explain why you have the red selection handles but cannot see anything: to fit the whole symbol into the window the zoom is so far out that you cannot see individual objects.Feel free to email a project file that shows the problem to techsupport@stardraw.com and we will be happy to investigate further.You might find it useful to watch the movie "Blank Imported DWG" at the bottom of https://www.stardraw.com/sd7/movies Assuming my suspicion is correct you will be able to use the same technique to fix the UDP symbol by editing it: in the Product Browser, rightclick on the UDP and choose Edit Symbols, then use the technique described in the movie to locate and remove any displaced objects.
