3DLINE

Removed. 3D Line entities are automatically converted into Line entities for existing drawings

ATTDEF

The text acquisition portion of this command has been updated with a new prompt that allows selection of the new text alignment options. However, you can still enter Release 10 options, such as Center, Middle, Right, Fit, etc. at the Justify/Style<start point> prompt

ATTEDIT

Accepts wild-card pattern lists at specification prompts

BLOCK

Accepts wild-card pattern lists for block names to list. Also, additional information about block types is reported

CHANGE

You can't change the layer of an object using the CHANGE command. You can use CHANGE Properties and CHPROP to change the layer of selected entities. The CHANGE elevation and CHANGE properties elevation options have been removed. You can use the MOVE command instead

DBLIST

Displays the space that entities are in. Viewport entities are listed, along with their ACTIVE/INACTIVE/ON/OFF status. New dimension types are listed, the dimension style for an associative dimension (if present) is listed, and the coordinates for user positioned dimension text are reported

`DDEMODES

There is a new text style selector button for setting the current text style

`DDLMODES

Now allows the assignment of viewport visibility for layers

DDUCS

Sets the UCS options for the current space

DIM

The RADIUS and DIAMETER subcommands now issue an additional prompt in some situations. This may cause failure of some old scripts and AutoLISP programs that use these commands

DTEXT

A new prompt provides access to new alignment options

DXFIN, DXFOUT

DXF files have been extended to contain the following:
+  New header variables
+  Group 30 (Z coordinate) values for EXTMAX, and EXTMIN
+  The new Viewport entity
+  Extended Entity Data (XDATA)
+  New fields for Block definitions
+  The new Dimstyle and Appid symbol tables
+  New Polyline flags and values for Polyface mesh entities
DXFIN - All non-baseline/left-justified Text, Attrib, and Attdef entities read from the DXF file are now rejustified. DXFOUT will never output more than 16 significant digits for any value, regardless of the level of precision requested. The value -0.0 will no longer ever occur

EXTEND

An Undo option has been added

FILES

There is a new option on the Files menu for unlocking files

FILLET

When filleting two Lines that cross, AutoCAD now retains the "picked" line segments. In previous versions, the shorter ends were trimmed no matter which points you used to select the Lines

HATCH

The ? option now prompts you for the pattern(s) to list, at which a wild- card pattern list is accepted. You can also enter a scale relative to paper space by using the XP option

`help/'?

Can now be called at subprompts for context-sensitive help

IGESIN, IGESOUT

Now handles additional entity types, including external references and Viewport entities

INSERT

A tilde (~) can be entered at the Block name prompt to display a File Dialog box, and wild-card pattern lists are accepted at the "Blocks to List" prompt

LAYER

Extended wild-card pattern lists are now accepted at the "Layers to List" prompt

LIMITS

Now sets limits for the current space, storing those values in the appropriate header variables

LINETYPE

Wild-card pattern lists are accepted at the "Linetypes to List" prompt

LIST

Same as DBLIST (see earlier section)

MINSERT

A tilde (~) can be entered at the Block name prompt to display a File Dialog box, and wild-card pattern lists are accepted at the "Blocks to List" prompt

MSLIDE

Making a slide while in paper space creates a slide showing the contents of whatever viewports are visible, active, and on. Making a slide while in model space creates a slide of the current viewport only

OSNAP

Running Osnap modes are now ignored during entity selection

PLOT/PRPLOT

Plots started from model space plot only the current viewport. Plots started from paper space displays the contents of those viewports that are visible, active, and on. 3D plots can now be rotated. There are also additional plot rotation options

PURGE

Now purges specified unreferenced Dimension Styles also

RENAME

Now allows the renaming of Dimension Styles and external references

`SETVAR

The ? option now accepts wild-card pattern lists for the variables to list. Additionally, setting certain variables sets the variable appropriate for the current space. In most cases, you can change a variable by typing its name without first entering `SETVAR

SHAPE

Wild-card pattern lists are accepted when listing loaded shapes. The listing also indicates if a shape definition is dependent on an external reference

STYLE

Allows wild-card pattern lists to be used when specifying text styles to list. Additional big-font capabilities have also been added

TABLET

Tablet calibration is effective only in the space where the calibration was performed

TEXT

A new prompt provides access to new alignment options

TRIM

An Undo option has been added

UCS

A wild-card pattern list is accepted at any of the ? option "UCSs to List" prompts

`VIEW

Saving a named view also saves the space that that view was created in, and that space is restored if the view is restored. Also, wild-card pattern lists are accepted when listing named views

VIEWPORTS, VPORTS

These commands are not active if TILEMODE is set to 0. If TILEMODE is nonzero, then these commands work as they did in Release 10, with the addition of accepting wild-card pattern lists when listing saved viewport configurations

WBLOCK

Entities written out with WBLOCK are placed into the model space of the output drawing unless the "*" option is used, in which case entities are placed in the same space they are currently in. Also, the "*"option will cause all entity handles, named views, UCS's, and viewport configurations to be retained

`ZOOM

The new option, Vmax, zooms to the limits of the virtual screen's 32K display space. This displays the maximum drawing area possible without a regeneration. The new option, XP, scales the magnification of a model space view relative to paper space
