Performance Monitoring Flashcards

A drawing takes a long time to save. Which system variable controls how much wasted space is allowed before AutoCAD performs a full save instead of an incremental save?

Answer: ISAVEPERCENT

ISAVEPERCENT sets the percentage of wasted space tolerated in a file before a full save is forced; 0 makes every save a full save.

Which XLOADCTL value turns on demand loading of external references and opens a copy of the referenced file so others can edit the original?

Answer: 2

XLOADCTL=2 enables demand loading using a copy of the xref, leaving the original available to other users.

To get the most benefit from xref demand loading, which INDEXCTL setting should be saved in the referenced drawing?

Answer: 3 - layer and spatial indexes

INDEXCTL=3 creates both layer and spatial indexes so only the needed layers and clipped regions of the xref are loaded.

Switching between layout tabs triggers a regeneration every time. Which variable setting caches model space and all layouts to avoid this?

Answer: LAYOUTREGENCTL = 2

LAYOUTREGENCTL=2 caches the display list for model space and every layout, so tab switches skip the regen at the cost of more memory.

Which command opens the Graphics Performance dialog box where hardware acceleration can be turned on or off?

Answer: GRAPHICSCONFIG

GRAPHICSCONFIG opens the Graphics Performance dialog that controls hardware acceleration and related display effects.

A drawing contains thousands of densely hatched regions and zooming is sluggish. Which setting temporarily stops displaying fills and hatches to speed up display?

Answer: FILLMODE = 0

Setting FILLMODE to 0 suppresses the display of fills, solid hatches, and wide polylines after a regen.

Which command checks the current drawing for integrity errors and can fix them when you answer Yes to the prompt?

Answer: AUDIT

AUDIT examines the open drawing for errors and corrects them if you choose to fix detected errors.
