Discretizing Curves

Define a geometrical set as the Define in Work Object.
Select the curve to process.
Select a discretization mode from the Mode list.
Key-in the requested parameter values.
1. Enter a Sag: Maximum distance between the input curve and the theoretical chord connecting two successive positions of the scan.
2. Enter a Step: Maximum distance between two successive positions on the scan.
3. Define Points: Number of positions N.
  The length of the curve is divided by (N-1), providing a constant curve-length or curve-parameter increment.
4. Enter an Increment.
5. For Direction+Increment, enter the plane Direction.
  The origin of the reference plane is (0,0,0).
