How to remove or eliminate?This problem has seriously affected the drawing problem of our design.。

 this is opening using OPM CE update4   his is opening using OBD CE update5

Attached is the picture I drew with OBD update5. You open it with OPM CE. Is it bottom cable? There are two problems caused by projection lines. One is that it is impossible to export drawings in other formats, Another problem is too laggy graphics, which causes OPM to run very difficult, and the software system crashes.

Can you help me?
