I posted a problem we've been experiencing where, using the zoom commnad, you get a "bad pick" if you do it too fast in a drawing with xrefs.
I just experienced a similar problem with the erase command. I type my alias for erase, enter the commnad, pick a window around a short line drawn in model space, right click to finish the command, look back at the selection and it says "0 found". If I grip the line by window selection it grips. If I do erase the same way as above but very very slowly with nearly a full second beween click, it finds the line and erases it. If I unload the xrefs, everthing works normally.
We xref large plans into modelspace and then draw over them. An example would be a several storey apartment buildging with the concrete structure plan on one drawing ref'd in, the walls and partitions on another plan ref'd in, then draw a detail on the correct locaiton in plan in the drawing where the others are ref'd.
We bring the references in as overlays.
We're using 2010. We have new dual core machines with decent specs.
Anyone else have a similar experience? or know a solution?
