Drawing orgins and file size and Autocad speed.

I have some very large drawings slowing down my computer The drawings have the origin is very far form the drawing entities. If I move the origin closer to the entities would that speed up the drawing loading, regen's etc

for AutoCAD. If so is there a way to move the origin closer to the entities?

Thank you,

I'd move the objects towards the origin. Do a test run then compare. What do you have to lose?

Re: file size. What is a typical file size and what, if anything, have you done to clean up the drawings and possibly reduce the overall file size?

Are these 2D or 3D drawings?

I have tried to move entities to the origin as a test but my computer is not able to handle that.

I would say 70,000KB with a 120,000 Kb xref. (2 d drawings)

The are large map drawings with AutoCAD map.

I am trying to figure out how to get faster performance with what I have.

Thank you,

What steps have you taken to reduce the file size?

What are your system specs?

Is this computer on a network or is it a stand-alone workstation?

We had dwg's almost crawl on opening and found it was a DOT linetype that was the culprit from a 3rd party software it basicly drew a repeated dot. Make sure you only have Autocad linetypes and no SHX attached linetypes.

With map drawings, the coordinates might be deliberately far from origin. I would be careful about moving them.
