Geometric Panel

Auto Constrain

Applies geometric constraints to a selection set of objects based on orientation of the objects relative to one another.

Coincident (GEOMCONSTRAINT)

Constrains two points together or a point to a curve (or an extension of a curve).

Colinear (GEOMCONSTRAINT)

Causes two or more line segments to lie along the same line.

Concentric (GEOMCONSTRAINT)

Constrains two arcs, circles, or ellipses to the same center point.

Fix (GEOMCONSTRAINT)

Locks points and curves in position.

Parallel (GEOMCONSTRAINT)

Causes selected lines to lie parallel to each other.

Perpendicular (GEOMCONSTRAINT)

Causes selected lines to lie 90 degrees to one another.

Horizontal (GEOMCONSTRAINT)

Causes lines or pairs of points to lie parallel to the X axis of the current coordinate system.

Vertical (GEOMCONSTRAINT)

Causes lines or pairs of points to lie parallel to the Y axis of the current coordinate system.

Tangent (GEOMCONSTRAINT)

Constrains two curves to maintain a point of tangency to each other or their extensions.

Smooth (GEOMCONSTRAINT)

Constrains a spline to be contiguous and maintain G2 continuity with another spline, line, arc, or polyline.

Symmetric (GEOMCONSTRAINT)

Causes selected objects to become symmetrically constrained about a selected line.

Equal (GEOMCONSTRAINT)

Resizes selected arcs and circles to the same radius, or selected lines to the same length.

Show Constraints

Displays constraint bars for the selected objects with geometric constraints applied to them.

Show All

Displays all geometric constraints in the drawing.

Hide All

Hides all geometric constraints in the current drawing.

Constraint Settings

Controls the display of geometric constraints on constraint bars.

Dimensional Panel

Linear (BCPARAMETER)

Creates a horizontal or vertical constraint parameter based on the locations of the extension line origins and the location of the dimension line similar to the DIMLINEAR command.

Horizontal (BCPARAMETER)

Creates a horizontal constraint parameter by picking two constraint points. Valid objects include lines and polyline segments.

Vertical (BCPARAMETER)

Creates a vertical constraint parameter by picking two constraint points. Valid objects include lines and polyline segments.

Aligned (BCPARAMETER)

Creates an aligned constraint parameter using one of the following ways.

• Selects a point and a line object. The aligned constraint controls the distance between a point and the closest point on a line.
• Selects two line objects. The lines are made parallel and the aligned constraint controls the distance between the two lines.

Radius (BCPARAMETER)

Creates a radial constraint parameter for a circle, arc, or polyline arc segment.

Diameter (BCPARAMETER)

Creates a diameter constraint parameter for a circle, arc, or polyline arc segment.

Angular (BCPARAMETER)

Creates an angular constraint parameter by picking two lines or polyline segments or an arc. It is similar to an angular dimension.

Convert (BCPARAMETER)

Converts the dimensional constraints to constraint parameters.

Block Table

Displays a dialog box to define variations of a block.

Constraint Settings

Sets preferences in behavior when displaying dimensional constraints.

Manage Panel

Delete Constraints

Removes all geometric and dimensional constraints from a selection set of objects.

Construction Geometry

Converts geometry into construction geometry.

Block Constraint Status

Turns the constraint display status on and off and controls the shading of objects based on their constraint level.

Parameters Manager

Opens the Parameters Manager palette that includes all dimensional constraint parameters, reference parameters, and user variables in the current drawing.

Authoring Palettes

Opens the Block Authoring Palettes window in the Block Editor.

Block Editor Settings

Displays the Block Editor Settings dialog box.

Action Parameters Panel

Point (BPARAMETER)

Defines custom X and Y properties for the block reference.

Linear (BPARAMETER)

Defines the distance between two key points in the block definition.

Polar (BPARAMETER)

Defines a distance and angle for two key points in the block definition.

XY (BPARAMETER)

Defines an X and Y distance from the base point of a block definition.

Rotation (BPARAMETER)

Defines an angle for the block reference.

Flip (BPARAMETER)

Mirrors objects or the entire block reference about a reflection line.

Alignment (BPARAMETER)

Rotates the block reference about a point to align with other objects in the drawing.

Visibility (BPARAMETER)

Defines objects that will either display or not display within the block definition.

Lookup (BPARAMETER)

Defines user parameters that are determined by a lookup table.

Basepoint (BPARAMETER)

Defines a changeable base point for the dynamic block reference in relation to the geometry in the block.

Move (BACTIONTOOL)

Specifies that the selection set of objects moves when the action is triggered in a dynamic block reference. A move action can be associated with a point, linear, polar, or XY parameter.

Stretch (BACTIONTOOL)

Specifies that the selection set of objects will stretch or move when the action is triggered in a dynamic block reference. A stretch action can be associated with a point, linear, polar, or XY parameter.

Polar Stretch (BACTIONTOOL)

Specifies that the selection set of objects stretches or moves when the action is triggered in a dynamic block reference. A polar stretch action can only be associated with a polar parameter.

Scale (BACTIONTOOL)

Specifies that the selection set of objects scales relative to the defined base point when the action is triggered in a dynamic block reference. A scale action can only be associated with a linear, polar, or XY parameter.

Rotate (BACTIONTOOL)

Specifies that the selection set of objects scales relative to the defined base point when the action is triggered in a dynamic block reference. A scale action can only be associated with a linear, polar, or XY parameter.

Flip (BACTIONTOOL)

A set of objects is flipped around the reflection line of the flip parameter when the action is triggered in the block reference. A flip action can only be associated with a flip parameter.

Array (BACTIONTOOL)

Specifies that the selection set of objects arrays when the action is triggered in a dynamic block reference. An array action can be associated with a linear, polar, or XY parameter.

Lookup (BACTIONTOOL)

A set of objects is flipped around the reflection line of the flip parameter when the action is triggered in the block reference. A flip action can only be associated with a flip parameter.

Attribute Definition

Creates an attribute definition for storing data in a block.

Show All Actions (BACTIONBAR)

Make Visible (BVSHOW)

Makes objects visible in the current visibility state or all visibility states in a dynamic block definition.

Make Invisible (BVHIDE)
