Distances constructed from a line and an arc
Up to three distance constructions can be made from a line and an arc:
• Center distance:
The perpendicular distance from the line to the center of the arc
• Min distance:
The perpendicular distance from the line to the nearest point of the arc
• Max distance:
The perpendicular distance from the line to the farthest point of the arc
Distances from virtual line extensions will be shown if the line is not long.
To construct the distance between a line and an arc:
1 Touch the Measure Distance icon
2 Touch the line feature
3 Press the Enter key
4 Touch the arc feature
5 Press the Enter key
6 Press the Finish key
The center distance will be constructed. Alternative distance constructions can be selected from the drop-
down menu in the DRO window.
