On opening a C3D 2013 drawing, C3D hangs for about 5 minutes. At the bottom of the screen is the message: "Upgrading COGO points". This drawing is only 974KB.
The drawing is being opened from a network . I tried saving it on a local hard drive. That had no effect.
Could the dwg file be looking for a point file that may have been erased, moved or renamed?
Here is my check list to see whats going on.
This happened at least a dozen times while I tried various solutions this morning. This afternoon after lunch I opened the drawing again and it opened almost instantaneously. I changed nothing from when I closed the drawing this morning to when I opened it this afternoon.
Thank you all for your help.
