Hatching problems 2012

I have AutoCAD 2012 and when I hatch it takes forever and sometimes AutoCAD will

freeze for 10-15 minutes. This seems to happen with some drawing files worse than others. Anything I can do?

What causes it to be worse?

Have you tried different scenarios/methods to try to get it to work better?

What kind of objects are you using for boundaries? XREFs?

Are you using the pick point option or select object?

I don't know what causes it to be worse, the boundaries are lines that make up walls for my architectural floor plans, I don't hardly use x refs, never on my plans.

and I use pick point option and solid hatch.

The job that gave me the most trouble started as a copy and paste plan from the original architect, it was drawn so poorly I had to trace over it to create my own plan. It is a T.I. job. A restaurant.

I only use single lines to create walls as there are always revisions and such so it is quicker for me just to leave them that way.

also, I did the AEC to ACAD and error check to try and see if that helped but it did not.

Sometimes, the area picked LOOKS closed but due to a couple of lines not meeting, AutoCad may find a boundary MUCH larger than where you picked. If the area is quite large, solid hatch can take a really long time to fill in.

I figured it out. It was not the boundaries. The file that was causing the problem was originally from an architect and it was huge, for reasons unknown. I had to clean it up and copy and paste into a small file template and now no more issues.
