Ribbon cycle options.
The Insert tab includes a Point Cloud panel and Content panel with access
to Design Center and Autodesk Seek web service. Autodesk Seek has been
removed from the Output tab.
The View tab has been updated to include the Visual Styles panel. The
Windows panel includes new User Interface and Toolbar controls that enable
you to toggle the display of various user interface elements, including
Autodesk ViewCube and ShowMotion navigation widgets, the Navigation bar, and
the Text window. The Status bar controls, which have been removed from the
Windows panel, are now only on the Status bar.
Customize User Interface dialog box now supports Fold panels.
Five new predefined visual styles including: Shaded,
Shaded with Edges, Shades
of Gray, Sketchy, and X‐Ray.
Object Visibility enable you to control object
visibility independent from layer
Object Visibility tools are accessible from the right‐click menu when
objects are selected as well as when no objects are selected. When you use
the Isolate Objects tool, only the selected objects remain visible in the
drawing. All other objects are hidden. The OBJECTISOLATIONMODE system
variable controls whether isolated/hidden objects persist between drawing
sessions. Default setting is temporary for current drawing session with
value 0. To persist use value 1. A lightbulb icon on the status bar
indicates whether object isolation is active in the drawing.
Select Similar tool enables you to select an object and
automatically include all other objects of the same type and with the same
properties, in a new selection set. You can access it from the right‐click
menu when objects are selected.
Add Selected tool enables you to quickly create a new
object in your drawing based on the properties of an existing object. For
example, if you use the Add Selected tool and select a polyline, AutoCAD
automatically launches the PLINE command with basic object properties
including color, layer, linetype, linetype scale, plotstyle, lineweight,
transparency, and material preset to match the selected object.
A Settings option (accessible when you enter SELECTSIMILAR at the command
line) enables you to specify which properties to filter. If only the Layer
property is enabled when you select a circle, for example, AutoCAD
automatically selects all circles on the same layer as the one you selected.
If both the Layer and Linetype properties are enabled, however, AutoCAD
selects only the circles on the same layer and with the same linetype as the
The Select Similar tool also enables you to select more than one object
and create the matching selection set accordingly. For example, if the Layer
filter is enabled and you select two circles, each on different layers,
AutoCAD selects all the circles on both layers. If, instead, you select a
circle and a line, AutoCAD selects all the circles on the same layer as the
selected circle and all the lines on the same layer as the selected line. In
addition to general object properties, you can filter selections based on
objectspecific properties, including object style and reference name. Object
Style properties apply to text and mtext, leaders and mleaders, dimensions
and tolerances, and tables and multilines. Reference names apply to blocks
and externally referenced files, including xrefs and images as well as PDF,
DWG™, or DGN files.
In addition to the new Select Similar tool, a new option has been added
to the PICKADD system variable. When PICKADD is set to a value of 2 (as it
is now by default), objects that you select using the SELECT command remain
selected in a “pick first” state even after you end the SELECT command.
Easily select overlapping objects using the new selection cycling
functionality. You can enable selection cycling from a control on the Status
bar (right click to access the Selection Cycling options). When you try to select an object that overlaps other objects, AutoCAD
displays a list of all the overlapping objects. As you pass the cursor over
an object in the list, the relevant object in the drawing highlights, click
on any object in the list and it gets selected. You can also click on the
same location multiple times and the objects with be selected one at a time.
To filter the type of subobjects displayed (vertices, edges, or faces) use
the SUBOBJSELECTIONMODE system variable. You can also set this option with
the SELECTIONCYCLING system variable.
The Action Recorder enables you to delete or insert user
messages for View Change operations. The macro list displays the most
recently used macros above the separation bar and all available macros below
The 2D parametric functionality has been enhanced, and includes predefined
command macros to access options within in the GEOMCONSTRAINT and
For example, instead of launching the GEOMCONSTRAINT command and then
selecting the Perpendicular option, you can launch the GCPERPENDICULAR
command directly. Repeating the last command automatically repeats the last
command as well as the specific option.
Object highlighting when you roll over an icon on a constraint bar or when
you select a parameter in the Parameters manager supports the Visual Effects
settings you specify on the Selection tab of the Options dialog box (dashed
and thickened by default). Additional improvements to geometric and
dimensional constraint functionality enable you to create and edit
parametrically constrained geometry faster than ever before.
AutoCAD 2011 significantly simplifies the process of adding geometric
constraints to 2D AutoCAD geometry. AutoCAD can infer geometric constraints
as you create and modify geometry. A new Infer Constraint button on the
status bar enables you to toggle inferred constraints on and off similar to
toggling object snaps on and off. This toggle is also available on the
Geometric tab of the Constraint Settings dialog box.
Using inferred constraints automatically applies coincident constraints
for Endpoint, Midpoint, Center, Node, and Insertion objects snaps. For
example, if you draw a circle by snapping its center to the midpoint of a
line, AutoCAD automatically applies a coincident constraint between the
center of the circle and the midpoint of the line. If you move the circle,
the line goes with it. The same powerful functionality applies to editing
commands. If, for example, you copy the insertion of a block to the endpoint
of a line, AutoCAD automatically applies a coincident constraint between
those two points. When you move the line, the block maintains its position
at the endpoint of the line.
In addition to creating point‐to‐point coincident constraints with the
previously mentioned object snaps, you can use the Nearest object snap to
apply a coincident constraint between a point and an object. For example, if
you draw the center of a circle on a line using the Nearest object snap, the
center of the circle has the flexibility of moving anywhere along the line
including the virtual extension of the line.
The Perpendicular and Tangent object snaps automatically apply
perpendicular or tangent constraints between the object being created or
edited and the object being snapped to. They also apply a point‐topoint or
point‐to‐object coincident constraint if appropriate. Using the Parallel
object snap automatically applies a parallel constraint but no coincident
constraints are applied since, by definition, the two objects never
intersect. When you draw horizontal or vertical lines and polyline segments,
inferred horizontal and vertical constraints automatically apply to those
Inferred constraints enhance the behavior of rectangles, fillets, and
chamfers by automatically applying appropriate geometric constraints. For
example, if you draw a rectangle (using the RECTANG command), AutoCAD
automatically applies a pair of parallel constraints and a perpendicular
constraint to the closed polyline. When you modify the size and shape of the
rectangle, you can rest assured that it will remain a rectangle with
parallel sides and perpendicular corners. Creating a fillet automatically
applies coincident and tangent constraints between the newly created arc and
the existing pair of lines helping maintain the fillet even when the arc or
lines are modified. Similarly, creating a chamfer applies coincident
constraints between the newly created line and the existing pair of lines.
Even after you’ve applied constraints, you can temporarily relax them by
pressing the CTRL key while editing constrained objects.
Improved support of geometric constraints for ellipses and
text. You can now apply Parallel, Perpendicular, Collinear, Horizontal, and
Vertical constraints between the major or minor axes of an ellipse and other
Similarly, you can apply Parallel, Perpendicular, Collinear, Horizontal,
and Vertical constraints to the rotation angle of text objects. In addition,
text and mtext objects behave consistently and predictably, with the
identified insertion point of the object being the constrainable point.
One problem found is that to select the text it is needed to click a bit
below the text.
The AutoConstrain functionality in AutoCAD 2011 has been updated to
include the Equal constraint. When you use AutoConstrain with the Equal
option enabled, the Equal constraint is automatically applied to lines and
polyline segments of equal length and arcs and/or circles of equal radius.
Constraint bars are enhanced to provide more control and flexibility. You
can select multiple objects for showing or hiding constraint bars using
standard selection methods, including Window, Crossing, Fence, and Implied
Window/Crossing. Quickly display all constraint bars in their original
position using the new Reset option. And, a new setting in the Geometric tab
of the Constraint Settings dialogs enables you to show constraint bars when
objects are selected even if those constraint bars are currently hidden.
When the geometry is no longer selected, the temporarily displayed
constraint bars are, once again, hidden. When you move a constraint bar and
then edit the related geometry, the constraint bar maintains its position
relative to the geometry.
new constraint icons for Fix, Horizontal, and Vertical constraints visually
indicate whether they apply to an object or to a point. The symmetric
constraint icon is also updated to indicate whether it is identifying a
symmetrical point or object, or the symmetric line.
The DIMCONSTRAINT command includes a new Convert option to convert
associative dimensions to dimensional constraints rather than it being the
When entering dimensional constraint values in‐place, you can click on an
existing dimensional constraint to insert the constraint name. When dynamic
dimensional constraints reference another parameter, the parameter text is
prepended with “fx:” to help prevent you from accidentally assigning a
constant value to a parameter that references other variables.
tools on the Dimensional Panel of the Parametric tab provide you with more
control over the display of dimensional constraints. Using the Show/Hide
tool you can select the specific dimensional constraints you want to show or
The Parameters Manager offers significant improvements. It includes a new
Filters pane where you can define parameter groups that display a subset of
the parameters. Create new filter groups using the button at the top of the
Parameters Manager or by selecting the option from the rightclick menu. With
your filter groups created, you can then drag parameters into them. The
right‐click menu for parameters in the Parameters Manager is updated with
additional options including the ability to display the Filter tree and to
remove parameters from a group.
A new search box filters the parameters displayed in the grid control
based on the parameter name. Column tooltips display the full name of the
column as well as a description.
Additional enhancements to the Parameters Manager simplify the
terminology for dimensional constraints and user variables created in the
drawing editor versus the block editor. The Show column in the Block Editor
includes a new option to convert between dimensional constraint parameters
or user parameters defined in the drawing editor versus the block editor. In
the Block Editor, icons are displayed for action parameters, attributes, and
AutoCAD 2011 includes a new transparency property that enables you to
apply transparency to objects and layers in the same way you apply colors,
linetypes, and lineweights.
You can set transparency by layer, by block, or individually for an
object. The default transparency value for layers and objects is 0, and you
can set it as high as 90.
The Layer Properties Manager (palette and dialog), the Layer States
Manager, the Layer Filter dialog, and the Layer Translator have all been
updated to reflect the new transparency property. In the Layer Properties
Manager, a new column for Transparency is available in modelspace and
layouts, and a column for Viewport (VP) Transparency is available in layouts
and floating modelspace viewports.
You can set transparency for individual objects just like color and
linetype. Setting a transparency value for an individual object overrides
the layer transparency setting for that object. You can access object
transparency from a number of places: the Properties palette, Quick
Properties, or the ribbon. The new CETRANSPARENCY system variable sets the
transparency property for new objects.
The SetByLayer Settings dialog has been updated to include Transparency
as one of the available properties.
Transparency has also been added to the Quick Select, Filter, and Match
Property Settings dialogs as well as the CHPROP, CHANGE, ‐LAYER, VPLAYER,
and LIST commands.
A button has been added to the status bar to enable you to temporarily
turn off transparency display (TRANSPARENCYDISPLAY system variable), similar
to the behavior of the lineweight display button. This does not affect
plotting. However, you have the option to turn off transparency when
plotting. The Plot and Page Setup dialogs both include a checkbox for
transparency (PLOTTRANSPARENCY), similar to the behavior for plot styles.
When this option is enabled, AutoCAD rasterizes the entire drawing for
plotting, slowing down the plotting process.
Prior to AutoCAD 2011, images had a setting, also called “transparency,”
that controlled whether the background of a bitonal image was clear or
opaque. This property has been renamed to “background transparency” to
distinguish it from the new “transparency” property. You can apply both
background and object transparencies to images in AutoCAD 2011.
You can control the orientation of text in linetypes with the alignment
code "U". GAS and HOT_WATER_SUPPLY already has this in the new .LIN files.
Jump List support.
The following outlines the additions and changes made to the ActiveX API
in AutoCAD 2011 and AutoCAD 2011-based products.
Selection cycling should benefit from also be able to show layer of
objects. Imagine if you have two identical objects and only the layer is
different. Another thing that might be helpful is to be able to use the up
and down arrows on the keyboard to activate the Selection dialog. Now you
have to either stay still and click multiple times or to move the mouse to
the Selection dialog box.
