AutoCAD Layers and Organization 2 — Questions and Answers
Question 1: Which command opens the Layer Properties Manager in AutoCAD?
- LAYERPROP
- LA
- LMAN
- LAYER (Correct answer)
Correct answer: LAYER
The LAYER command (or its alias LA) opens the Layer Properties Manager dialog.
Question 2: What does it mean when a layer is set to 'Frozen'?
- The layer is locked from editing but still visible
- Objects on the layer are not displayed and not regenerated (Correct answer)
- The layer color is grayed out
- The layer cannot be renamed
Correct answer: Objects on the layer are not displayed and not regenerated
Frozen layers are invisible and excluded from regeneration, improving performance on large drawings.
Question 3: Which layer property controls whether objects can be selected and edited?
- Frozen
- Off
- Locked (Correct answer)
- Plot
Correct answer: Locked
Locking a layer prevents its objects from being selected or modified while keeping them visible.
Question 4: What is the primary difference between turning a layer Off versus Freezing it?
- Off hides objects; Freeze also skips the layer during regeneration (Correct answer)
- Freeze hides objects; Off also deletes them
- Off locks the layer; Freeze makes it read-only
- There is no functional difference
Correct answer: Off hides objects; Freeze also skips the layer during regeneration
Turning a layer Off hides it but still includes it in regenerations, while Freeze excludes it entirely for better performance.
Question 5: In AutoCAD, which layer CANNOT be deleted or renamed?
- Layer 0 (Correct answer)
- Defpoints
- Any layer that contains objects
- Both Layer 0 and Defpoints
Correct answer: Layer 0
Layer 0 is a special default layer that cannot be deleted or renamed, though Defpoints is also protected from deletion.
Question 6: What does the 'Plot' property on a layer control?
- Whether the layer prints when you send a drawing to a printer or plotter (Correct answer)
- The line weight used when plotting
- The plot style assigned to the layer
- The scale at which layer objects are plotted
Correct answer: Whether the layer prints when you send a drawing to a printer or plotter
The Plot toggle determines whether a layer's objects are included when the drawing is printed or plotted.
Question 7: When you use the MATCHPROP command and include 'Layer' as a property to match, what happens?
- The source object moves to the target object's layer
- Target objects are moved to the source object's layer (Correct answer)
- Both objects are moved to Layer 0
- Layer names are swapped between the two objects
Correct answer: Target objects are moved to the source object's layer
MATCHPROP transfers the source object's layer assignment to all selected target objects.
