Select the rotational symmetry of the workpiece from the drop-down list.
The rotational symmetry
specifies the number of distinct orientations in which the
workpiece's outline looks the same. For example, select Rectangular Symmetry when
working with a rectangle or an ellipse and select Squared Symmetry when working with a
square or four-vertex star. The following table shows some examples.
Types of Symmetry
Good Examples Bad Examples
No symmetry
Circular symmetry
Rectangular symmetry
Triangular symmetry
Square symmetry
Pentagonal symmetry
Hexagonal symmetry
NOTE:
The rotational symmetry defines the amount of unique picking orientations
of an object. It is dierent from other types of symmetry. Items having lines
of symmetry do not necessarily have any kind of rotational symmetry.
