BIM Software Tip: How to Fix Slow Saving Times When Using Save or Qsave Commands in AutoCAD
Issue:
When AutoCAD uses multiple external reference files, executing the save or Qsave commands can take an unusually long time.
Cause:
This delay often occurs due to corrupted graphics in nested external reference files that have expired or become invalid.
Solution:
– Change the VISRETAIN system variable to 0, then save your drawing again. Once saved, the command should execute at normal speed. This issue is typically caused by the way nested external references are represented.
Additional Tips:
Set VISRETAIN = 1 to retain visibility settings.
If you remove some external references and save the drawing, observe the save time:
- If saving becomes faster, it indicates the problematic external reference has been successfully removed.
- If saving remains slow, the problematic file is still loaded as an external reference in the nested list.
