I am trying to do a feasibility study for board floorpla in Allegro, so I took my older design and wanted to delete blocks of components. The problem is when I select a block of 50 components with traces/shapes/vias and use the delete mode, Allegro hangs for about 3 minutes before removing the selected objects. I already disabled online DRC, but it is still that slow.
What is causing this, and how can I speed it up?
 

Hi,

I am assuming your using pcb editor with open GL on. Have you tried disabling open GL display by going to Setup - User Preferences - Display - disable_openGL?

I experience that kind of lag when I remotely access workstations so I tend to turn off open GL but if Im running my allegro in my own PC openGL is fine.

Maybe disabling dynamic shapes should help (on slow computers, dynamic shpae can be verry long on large pcb)
