Internal / External Arc Cycles

The Internal and External Arc cycles are defined with the following parameters:

Approach/Retract

• In the Arc cycles, the Distance is measured from the perimeter of the arc along the radial direction.

Modify geometry

• The Offset value defines an additional offset from the contact points in the radial direction of the arc.

Levels

• The Reposition height value defines an additional level for the Probe tool along the Z-axis that the tool ascends to when reaching the retract distance. This parameter enables you to avoid obstacles without retracting to the clearance level. You can click the lock icon to disable the field for editing.
• The Z-level value defines the Z-coordinate of the contact point. The selection button enables you to select the point directly on the model by using the Pick on plane dialog box.

Shrink geometry

• The Move start point field enables you to reduce the measurement distance by shifting the start point by the specified value. The point is shifted along the arc perimeter, in the clockwise direction.

• The Move end point field enables you to reduce the measurement distance by shifting the end point by the specified value. The point is shifted along the arc perimeter, in the counterclockwise direction.

No. touch points

• The Number of touch points defines the number of touch points required to perform the internal/external arc measurement. These points are distributed evenly along the arc perimeter.

Repetitive touches

• This field enables you to define the number of touches in each contact point.
