Scale List Cleanup
Problem:
If you’ve ever had problems within AutoCAD, while using drawings with xrefs; then this is hopefully a step toward solving your miseries. Common symptoms of this effect are; slow processing speed, delayed response to command types, agonising movement of the cursor when adjusting viewports, etc, etc.
Knowledge:
“When a file contains excess scales, performance may be negatively affected. Eventually, the file may become unusable. To use the file, the extra scales must be removed” (www.cadtutor.net). There is a command type within AutoCAD that repairs affected files by removing these unwanted excess scales.
Procedure:
Have the drawing open in your AutoCAD application and then type the following command: ‘-scalelistedit’
Next it asks: Enter option? Type ‘R’ for Reset
Finally it asks: Reset scale list to defaults? Then type ’Y’ for Yes
Further tips:
It’s a good idea at this point to also Purge & Audit the drawing in order to optimise the file.
Simply type and hit enter for the following: ’PU’ for Purge - and then select ‘Purge All’ until nothing is left to purge. ‘AUDIT’ for audit - and then type ‘Y’ for yes when it asks if you want to Fix any errors detected.


Ask Andy Scollen about the Scalelist Cleanup Utility. I can tackle whole folders of drawings files.
