Auxiliary points
Auxiliary points are entered for arcs in the same way as for straight lines.
Identifying closed contours
You can identify the beginning and end of a closed contour with the CLSD
soft key. This reduces the number of possible solutions for the last
contour element.
Enter CLSD as an addition to another contour data entry.
The closed contour results from the geometric context, for example from
a tangential transition.
