ACP ACP Layer Management and Object Properties 1 — Questions and Answers
Question 1: Which command opens the Layer Properties Manager in AutoCAD?
- LAYER (Correct answer)
- LMAN
- LAYPROP
- LAYERSTATE
Correct answer: LAYER
The LAYER command (or LA shortcut) opens the Layer Properties Manager palette where you create, modify, and organize layers.
Question 2: What is the difference between a Frozen layer and an Off layer in AutoCAD?
- Frozen layers are excluded from regeneration and cannot be made current; Off layers are invisible but still regenerated (Correct answer)
- Frozen layers are invisible but still regenerated; Off layers are excluded from regeneration
- Frozen and Off layers behave identically
- Frozen layers are locked; Off layers are unlocked
Correct answer: Frozen layers are excluded from regeneration and cannot be made current; Off layers are invisible but still regenerated
Frozen layers skip the drawing regeneration process, improving performance in complex drawings, while layers that are simply turned Off are still processed during REGEN but not displayed.
Question 3: What does locking a layer do in AutoCAD?
- Objects on the layer are visible but cannot be selected or modified (Correct answer)
- Objects on the layer are hidden from the display
- Objects on the layer are removed from the regeneration cycle
- Objects on the layer are moved to layer 0
Correct answer: Objects on the layer are visible but cannot be selected or modified
Locking a layer keeps its objects visible and snappable but prevents them from being selected, edited, or deleted, protecting reference geometry.
Question 4: Which command saves the current layer states (on/off, frozen, locked, color, linetype) so they can be restored later?
- LAYERSTATE (Correct answer)
- LAYERSAVE
- LAYSNAPSHOT
- LAYERSET
Correct answer: LAYERSTATE
LAYERSTATE opens the Layer States Manager where you save named snapshots of all layer settings and restore them at any time, useful for switching between drawing phases.
Question 5: What is the function of the LAYWALK command?
- Temporarily isolates each layer one at a time so you can walk through layers to review their content (Correct answer)
- Moves selected objects to a different layer while walking the cursor
- Renames layers in sequential order
- Merges all layers into a single layer
Correct answer: Temporarily isolates each layer one at a time so you can walk through layers to review their content
LAYWALK displays objects on one layer at a time as you cycle through the layer list, helping you audit which objects belong to each layer.
Question 6: Which command moves selected objects to the current layer?
- LAYCUR (Correct answer)
- LAYISO
- LAYMCH
- LAYMOVE
Correct answer: LAYCUR
LAYCUR changes the layer assignment of selected objects to match the current layer, a fast way to standardize geometry without using the Properties palette.
