How to decrease CPU usage when editing a drawing + answer.

(I thought I'd post this as a reminder: if one ever comes across this problem it might help you to remember to maintain the xrefs as well as the drawing itself.)

Hi,
Maybe I can find some answers here.
Since a month or so we are working on a new project.
The drawing I created (from scratch) contains several xrefs on wich I projected my installation works.
The DWG itsef is <700kB and contains 17 layouts.
Per layout at least 1 viewport.
THere are 3 layouts that carry either 2, 3 or 4 viewports.
Am I going to far with this? I mean, must I split the drawing in multiple dwg's? Can't imagine so but it might...
ie. when using command "line" it looks as if I have snap on and grid on, but thats not the case.
Any help would be welcome.

Answer already found:
One of the xref's had major errors, a big time audit recovered 75561 errors.
I did also purge to be shure it was okay...
Now it runs properly again.

In civil 3D they dont recommend using more than 5 layouts... which sucks. Im used to do entire sewer collection systems in one drawing i have had over 200 layouts in one drawing. But not any more, and further more they recommend breaking out each civil 3d object into its own seperate drawing and data reference in them to one drawing.

I don't "do" 3D only 2D plans and maps with installations: I am very happy with the fact that it runs again now for "I will not surrender !! LOL". It would be a mess if every project was split in several dwg's per discipline like gas / electric / plumbing and so on.

BTW: you say:
There is never time to do it correct the first time, but there is always time to do it over.

So you are telling me your first time wasn't correct... Well, I guess mine wasn't too, I'm still practicing.
