The shape of the features is defined by the curve.
These features can create a number of wire EDM operations. The types of operation are controlled by the Strategy tab.
Multiple curves in a single 2-axis wire feature
All wire EDM curves must lie in the XY plane or a plane parallel to the XY plane.
A single 2-axis Die, Punch, or Side feature can contain multiple curves. In this case you have the option of setting separate start points and variable taper values for each curve, but all other settings apply to all of the curves.
If the feature has multiple operations, such as a retract followed by a cutoff, each operation is performed on each curve before moving on to the next operation. To change this ordering, manually reorder the operations in the Operations List.
