Layer management commands related to Workzones:

  • LR     Layer Resolve.

  • LR+     Layer Resolve add (Modelspace)

  • LR-     Layer Resolve minus (Modelspace).

  • LS        Layerstate Save (AutoCAD).



AutoCAD term - Layer conditions of On, Off, Freeze and Thaw, Lock etc.


ACADUI term - A combination of a Layerstate, View and UCS.


ACADUI Layer command option - Freshly Freezes and Thaws the current layer set to display a single Workzone.  This command processes all layers including those newly created since the last Resolve or Layerstate Save but ignores View and UCS.  Used in Tilemode 1 (Modelspace) or Tilemode 0 (in an active Modelspace Viewport).


ACADUI Layer command option - If used in Tilemode 0 in an active Modelspace Viewport it will Restore a previously saved Workzone. If used in Tilemode 1 (Modelspace) it will Restore a Workzone (Layerstate, View and UCS combination).


  • LR, LR+ and LR- apply only to Layers and Modelspace and do not affect View or UCS.

  • WS Saves the current layer state, view and UCS.  Can be any combination of layers.

    • If in Tilemode 1 the current Modelspace Workzone will be saved.          

    • If in Tilemode 0 in an active Modelspace Viewport a Workzone relevant to the Viewport will be saved.

  • WR when in Paperspace means Workzone Resolve.

  • WR when in Modelspace a named Workzone is Restored.

Typical uses:

  • LR, LR+ and LR- are used in Modelspace to view and edit Workzones.

  • WS is similar to YS but also saves the current View and UCS.

  • WR is used in Paperspace Layouts to automatically Resolve selected Viewports VPLAYER conditions prior to plotting.

  • WR is used in Modelspace to Restore a previously saved Workzone.

Let’s explain those L commands again:


LR resolves Layer visibility by freezing and thawing layers to display a particular Workzone. This is useful for viewing, editing and plotting a single Workzone.


LR+ is similar to LR except that the new Workzone is added to the existing rather than resolving a fresh Workzone.  This is useful for comparing two or more Workzones of the same model for alignment and content.


LR- is similar to LR+ except that the new Workzone is removed from an existing combination of Workzones.  This is useful for adjusting a combination of three or more Workzones when you don’t want to use LR to resolve the model back to a single Workzone.


YS is unrelated to ACADUI Workzones.  It’s just a convenient way of saving a named AutoCAD Layerstate.  Handy if you want to save a particular combination of layers for some reason.

Other useful related commands:


C@  Copy @at to make a coincident copy of selected objects.


GFI chanGe Field ID changes the ID of selected objects.


New when used as a selection option to the GFI command will collect the New objects just created and change them to another ID.

Practical application:

Open the supplied sample drawing “Cranford.dwg”.

Press F11 to switch to Tilemode 1.

Press L* <enter> to turn on and thaw all layers.

Read the status line at the bottom of the screen.  It will show you the current Workzone name and layer length setting:

wkzn.  001P01, lyrlen. 12chr, or something similar and more.

If the lyrlen is not set to 12chr press F7 until it is.





Press LR <enter> to start Layer Resolve command in Modelspace and note the resulting prompt.

Layers to RESOLVE:

Current DT codes: 001:G, 002:D, 004:S, 008:O, 016:L, 032:H, 064:E, 128:R, 256:F

Enter three digit number or key-letter:/<[001]>/<:label scheme/ALTMENU:>

Press 001 or G explicitly or [spacebar] or <enter> to use/accept the default value 001.

<<ent/sub-ent>>/<[E]>/Enter view-point-code:

Press P

<<ent/sub-ent>>/<[02]>/Enter view-ID-code:

Press 01

Processing...please wait.


Press ZE <enter> or Z <enter> E

Press LR+ <enter>



You are given a reminder of the current Drawing-type codes and prompted to enter a new three digit code or single character mnemonic.

The drawing is currently resolved into 001GP01 (or GP01) General arrangement Plan level 01.  So let’s add level 02.

Command:  LR+ <enter>

Layers to ADD:
Drawing codes: 001:G 002:D 004:S 008:O 016:L 032:H 064:E 128:R 256:F
Workzones: GP01  GP02  GP00  GPS1  GSS1  GS01  GP-1
Enter three digit number or key-letter:/<[001]>/<:label scheme/ALTMENU:>001,
DT-code = 001

Press G (or 001)

<<ent/sub-ent>>/<[P]>/Enter view-point-code:

Press P

Enter 2 characters: or tab:>

Press 02

Processing...please wait.

View display is increased by:  001P02

Note that the program only accepts valid entries and prompts to try again if an invalid entry is attempted.

Note the addition of the loft space in the roof.  This allows careful checking of structural alignments.
