Adds a parameter with
grips to a dynamic block definition.
Access Methods
Ribbon: Block
Editor contextual tab 
Action Parameters panelSummary
You can use the bparameter command
only in the Block Editor.
A parameter defines custom properties for the block reference. After
you add a parameter, you must associate an action with the parameter
to make the block dynamic.

Alignment
Ribbon: Block
Editor contextual tab Action Parameters panel Alignment
Rotates the block reference
about a point to align with other objects in the drawing.
- Specify Base Point of Alignment
-
Specifies the grip about
which the block reference will rotate to align with another object in
the drawing.
- Name
-
Sets the Name custom
property for this parameter.
- Specify Alignment Direction
-
Determines the angle
of alignment for the block reference.
- Type
-
Determines whether the
block reference will align tangent or perpendicular to objects in
the drawing.
Base
Ribbon: Block
Editor contextual tab Action Parameters panel Basepoint
Defines a changeable
base point for the dynamic block reference in relation to the geometry
in the block.
- Specify Parameter Location
-
Determines the default
location of the basepoint for the block definition. This will be
the location of the basepoint grip in the block reference.
Point
Ribbon: Block
Editor contextual tab Action Parameters panel Point
Defines custom X and Y properties
for the block reference.
- Specify Parameter Location
-
Determines the X and Y location
of the point parameter in the block definition. This will be the
location of the point grip in the block reference.
- Name
-
- Label
-
Defines a custom descriptive
label for the location of the parameter.
- Chain
-
Determines whether the
parameter is included in the selection set of an action that is
associated with a different parameter.
- Yes. A change
to an action associated with this parameter will also trigger other
actions associated with this parameter, just as if you had edited
the parameter through a grip or custom property.
- No. Associated
actions are not triggered.
- Description
-
Defines an extended description
of the Label custom
property. When the block reference is inserted, this description
is displayed at the bottom of the Properties palette.
- Palette
-
Specifies whether the
Label custom property is displayed in the Properties palette when
the block reference is selected in a drawing.
Linear
Ribbon: Block
Editor contextual tab Action Parameters panel Linear
Defines the distance
between two key points in the block definition.
- Specify Start Point/Endpoint
-
Specifies the key points
for the parameter in the block definition.
- Name
-
- Label
-
- Chain
-
- Description
-
- Base
-
Specifies the Base Location
property for the parameter.
- Startpoint. The
start point of the parameter remains fixed when the endpoint of
the parameter is edited in the block reference.
- Midpoint. The
midpoint of the parameter remains fixed, and the start point and endpoint
of the parameter move simultaneously equal distances from the midpoint.
- Palette
-
- Value Set
-
Limits the available
values for the parameter to the values specified in the set.
- List. Specifies
a list of available values for the parameter in a block reference.
- Increment. Specifies
a value increment and minimum and maximum values for the parameter
in the block reference.
- Specify Label Location
-
- Enter Number of Grips
-
Determines the number
of grips that will display in the block reference.
- 0. No grips
will be displayed in the block reference. Rather, the selected geometry
can be edited in the Properties palette or a lookup
table.
- 1. A grip will
be displayed at just the endpoint of the parameter.
- 2. A grip will
be displayed at both the start point and endpoint of the parameter.
Polar
Ribbon: Block
Editor contextual tab Action Parameters panel Polar
Defines a distance and
angle for two key points in the block definition.
- Specify Base Point

-
- Label
-
- Chain
-
- Description
-
- Palette
-
- Value Set
-
- Specify Endpoint
-
Determines the distance
and angle from the base point. The distance and angle are custom properties
in the Properties palette.
- Specify Label Location
-
- Enter Number of Grips
-
XY
Ribbon: Block
Editor contextual tab Action Parameters panel XY
Defines an X and Y distance
from the base point of a block definition.
- Specify Base Point

be displayed at the endpoint of the Y distance.
- 2. A grip will
be displayed at both endpoints.
- 4. Grips will
be displayed at all four corners of the parameter.
Rotation
Ribbon: Block
