I get annoyed at when things are imported into a parent drawing from another. I usually draw a big circle at the intended origin of the drawing. Then import the new drawing way off in the tulies. Place a circle there at same intended exact spot. Then do a simple MOVE and translate from one location (a center) to another (canter) and then am done with one phase.
Why then after explosion, does it not assume that the layers and respective colors for lines are exactly the same, but instead adds a whole new layer? Creating another PURGE situation?
