All drawing have the same problems. 90* of my drawings are in 2D wireframe with no parametric constraints and no recent blocks. I restarted my computer twice yesterday because AutoCad just would not execute a trim command and would just beach ball me for 20 min. I put the machine to sleep at the end of the day and this morning AutoCad works 10X better but still slower than it should. Moving and zooming is not smooth and the annoying Ortho is driving me crazy. Also snapping to a point half the time is impossible. Almost like a (-) magnet the curser jumps over the point and I can't ever hover over it.
