AutoCAD Layers and Organization 2

Question 1

Which command opens the Layer Properties Manager in AutoCAD?

Accepted Answer

LAYER

Answer

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'?

Accepted Answer

Objects on the layer are not displayed and not regenerated

Answer

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?

Accepted Answer

Locked

Answer

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?

Accepted Answer

Off hides objects; Freeze also skips the layer during regeneration

Answer

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?

Accepted Answer

Layer 0

Answer

Layer 0 is a special default layer that cannot be deleted or renamed, though Defpoints is also protected from deletion.
