LineWeight

Changes the lineweight of layers; prompts you:

1. Enter lineweight (0.00 - 2.11mm) - enter a number between 0.00 and 2.11
2. Enter name list of layers(s) for lineweight 0.00 mm <CurrentLayer> - enter the name(s) of layers, separating names with a comma, or else press Enter to apply the line weight to the default layer

TRansparency

Sets the entity transparency factor between 0 (fully opaque) and 90 (fully transparent); p rompts you:

• Enter transparency (0 - 90) - enter a number between 0 and 90; default is 0
• Layer(s) for transparency 0 <CurrentLayer> - enter the name(s) of layers, separating names with a comma, or else press Enter to apply the transparency level to the default layer

The 2DWireframe visual style ignores this setting; for it, use the TRANSPARENCYDISPLAY variable to control the level of transparency.

• Edit - Edits a saved layer state. prompts you:

1. Enter the name of the Layer State to edit or [?] - Type the name of saved layer state or type ? to list the saved layer states.

2. Click the Open button
   
   

• Export - exports a saved layer state in the current drawing to a layer state file (*.las). Prompts you:

1. Enter the name of the Layer State to export or [?] - type the name of saved layer state or type ? to list the saved layer states

2. Displays a File dialog. Type a name for the layer state file, then press the Save button.

turn layer ON

Turns layers on that had been turned off with the OFf option; prompts you:

Layer(s) to turn ON - specify the names of layer name(s) to turn on; separating multiple layer names with commas.

turn layer OFf

Turns layers off to hide their entities from view; prompts you:

Layer(s) to turn OFF - specify the names of layer name(s) to turn off; separating multiple layer names with commas.

The current layer cannot be turned off.

When layers are off, they are hidden from view. In most cases, you should probably use the Freeze option, as it offers more features.

Freeze

Freezes layers so that they are hidden from view; prompts you:

Layer(s) to Freeze - specify the names of layer name(s) to freeze; separating multiple layer names with commas.

The current layer cannot be frozen.

When layers are frozen...

• Entities are hidden from view
• Entities cannot be edited
• The extents of entities are ignored when the program calculates the drawing extents
• Entities are not included in operations, such as ViewBase, Print, Export, and PDFout. 

Thaw

Thaws layers that were previously hidden with the Freeze option; prompts you:

Layer(s) to Thaw - specify the names of layer name(s) to thaw; separating multiple layer names with commas.

LOck

Locks layers so that their entities remain visible but cannot be edited; prompts you:

Layer(s) to Lock - specify the names of layer name(s) to lock; separating multiple layer names with commas.

The current layer can be locked.
