Point Parameter (BPARAMETER) Adds a point parameter to the dynamic
block definition and defines custom X and Y properties for the block reference.
A point parameter defines an X and Y location in the drawing. In the Block
Editor, a point parameter looks similar to an ordinate dimension.
Linear Parameter (BPARAMETER) Adds a linear parameter to the dynamic
block definition and defines a custom distance property for the block reference.
A linear parameter shows the distance between two anchor points. A linear
parameter constrains grip movement along a preset angle. In the Block Editor,
a linear parameter looks similar to an aligned dimension.
Polar Parameter (BPARAMETER) Adds a polar parameter to the dynamic
block definition and defines custom distance and angle properties for the
block reference. A polar parameter shows the distance between two anchor
points and displays an angle value. You can use both grips and the Properties
palette to change both the distance value and the angle. In the Block Editor,
a polar parameter looks similar to an aligned dimension.
XY Parameter (BPARAMETER) Adds an XY parameter to the dynamic block
definition and defines custom horizontal and vertical distance properties for
the block reference. An XY parameter shows the X and Y distances from the
base point of the parameter. In the Block Editor, an XY parameter displays as
a pair of dimensions (horizontal and vertical). These dimensions share a
common base point.
Rotation Parameter (BPARAMETER) Adds a rotation parameter to the
dynamic block definition and defines a custom angle property for the block
reference. A rotation parameter defines an angle. In the Block Editor, a rotation
parameter displays as a circle.
Alignment Parameter (BPARAMETER) Adds an alignment parameter to the
dynamic block definition. An alignment parameter defines an X and Y location
and an angle. An alignment parameter always applies to the entire block and
needs no action associated with it. An alignment parameter allows the block
reference to automatically rotate around a point to align with other objects
in the drawing. An alignment parameter affects the angle property of the block
reference. In the Block Editor, an alignment parameter looks like an alignment
line.
Flip Parameter (BPARAMETER) Adds a flip parameter to the dynamic block
definition and defines a custom flip property for the block reference. A flip
parameter flips objects. In the Block Editor, a flip parameter displays as a
reflection line. Objects can be flipped about this reflection line. A flip parameter
displays a value that shows if the block reference has been flipped or not.
