Internal Accuracy?

[leane]

I keep having trouble adding detail layers to an already existing drawing. I start by selecting a layer with the largest (ie: 1-1/2") scale and then try to change the scale of my new layer to make it larger still (ie: 3" or 6"). A warning box keeps popping up with a note about internal accuracy. How do I control my files' internal accuracy? I've noticed that on the file I've had the problems on the internal accuracy is listed as .0 My file has been copied and modified at least ten times as the project has gone through numerous schematic design schemes and revisions. Looking back at the first file the intenal accuracy there is .0000 Help! This is most annoying.

Internal accuracy can be adversely affected by having layers in a drawing that differ greatly in scale, or by having objects in a drawing that are very far from the center. So...

1. Avoid having layers in a single drawing with that have big differences in scale. For example, two layers with 1"=200' and 4"=1" scales could cause a problem.

2. Make all layers visible, and then zoom out as far as possible so that you can see the entire drawing. Select all, and look for objects which lie very far from the center of the drawing. Moving or deleting these objects will improve the internal accuracy.
