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.
Visibility Parameter (BPARAMETER) Adds a visibility parameter to the
dynamic block definition and defines a custom visibility property for the block
reference. With visibility parameter, you can create visibility states and control
the visibility of objects in the block. A visibility parameter always applies to
the entire block and needs no action associated with it. In a drawing, you
click the grip to display a list of visibility states available for the block reference.
In the Block Editor, a visibility parameter displays as text with an associated
grip.
Lookup Parameter (BPARAMETER) Adds a lookup parameter to the dynamic
block definition and defines custom lookup properties for the block reference.
A lookup parameter defines a custom property that you can specify or set to
evaluate to a value from a list or table you define. It can be associated with a
single lookup grip. In the block reference, you click the grip to display a list
of available values. In the Block Editor, a lookup parameter displays as text.
Base Point Parameter (BPARAMETER) Adds a base point parameter to the
dynamic block definition. A base point parameter defines a base point for the
dynamic block reference relative to the geometry in the block. A base point
