Performance Monitoring Flashcards

A drawing received from a consultant fails to open normally. Which command should be used to attempt to repair and open it, including its external references?

The command-line -PURGE command includes a Regapps option that deletes unused registered application names.

Which command deletes duplicate and overlapping lines, arcs, and polylines to reduce object count?

OVERKILL removes duplicate geometry and merges partially overlapping or contiguous collinear objects.

Which statement correctly compares freezing and turning off a layer for performance?

Answer: Frozen layers are excluded from regeneration, while layers that are off are still regenerated

Objects on frozen layers are not regenerated, which improves performance in large drawings compared with simply turning layers off.

A drawing with thousands of text objects pans slowly. Which setting displays text as rectangular boxes after regen to improve performance?

Answer: QTEXT on (QTEXTMODE = 1)

Quick text mode replaces text with bounding boxes on regeneration to reduce display overhead.
