Troubleshooting Methods Flashcards

When you open drawings, file dialog boxes no longer appear and you are prompted at the command line instead. Which variable should you set to 1?

Answer: FILEDIA

Setting FILEDIA to 1 turns file navigation dialog boxes back on.

Objects in a layout viewport are missing, but they appear in model space. What is the most likely cause?

Answer: The layer is frozen in that viewport

Freezing a layer in a viewport (VP Freeze) hides it only in that viewport and leaves model space unchanged.

A linetype shows as continuous in a layout viewport but appears dashed in model space. Which settings work together to control linetype scale in paper space viewports?

Answer: PSLTSCALE and MSLTSCALE

PSLTSCALE and MSLTSCALE adjust linetype scale for viewport and annotation scales, and you must run REGENALL afterward.

Which command removes duplicate and overlapping lines, arcs, and polylines from a drawing?

Answer: OVERKILL

OVERKILL deletes duplicate objects and merges ones that partly overlap.

An object snap jumps to points at the wrong elevation in a 2D drawing that has objects at different Z values. Which variable makes snaps use the current elevation instead?

Answer: OSNAPZ = 1

When OSNAPZ is 1, the Z value of each snap point is replaced with the current elevation.

A drawing file is much larger than expected. You have already purged blocks and layers. Which item, often brought in from other files, should you purge next with -PURGE?

Answer: Registered applications (Regapps)

Running -PURGE with the Regapps option removes unused registered application IDs, which often build up from imported files.

You select objects first and then start a command, but AutoCAD ignores your selection. Which variable is the likely cause?

Answer: PICKFIRST is 0

When PICKFIRST is 0, noun-verb selection (selecting before you run a command) is turned off.
