Polar Stretch Pair Automatically adds two stretch actions, one associated
with the base point and one associated with the endpoint of the polar
parameter.
XY Move Automatically adds a move action associated with the endpoint of
the XY parameter.
XY Move Pair Automatically adds two move actions, one associated with the
base point and one associated with the endpoint of the XY parameter.
XY Move Box Set Automatically adds four move actions, one associated with
each key point on the XY parameter.
XY Stretch Box Set Automatically adds four stretch actions, one associated
with each key point on the XY parameter.
XY Array Box Set Automatically adds an array action associated with the XY
parameter.
Rotation Set Automatically adds a rotation action associated with the rotation
parameter.
Flip Set Automatically adds a flip action associated with the flip parameter.
Visibility Set Adds a visibility parameter to the dynamic block definition and
allows visibility states to be defined. No action is necessary with the visibility
parameter.
Lookup Set Automatically adds a lookup action associated with the lookup
parameter.
Constraints Tab (Block Authoring Palettes Window)
Provides tools for applying geometric constraints and constraint parameters
to objects. When you apply geometric constraint to a pair of objects, the order
in which the objects are selected and the point on which each object is selected
can affect how the objects are positioned relative to each other.
Geometric Constraints
Coincident Constraint (
GCCOINCIDENT on page 825) Constrains two points
together or a point to a curve (or an extension of a curve).
Perpendicular Constraint (GCPERPENDICULAR on page 834) Causes selected
lines to lie 90 degrees to one another.
Parallel Constraint (GCPARALLEL on page 833) Causes selected lines to lie
parallel to each other.
