- CTR+DIA allows you to create an arc by specifying start
- and end angles, a center position, and a diameter.
-
- Enter a value for the diameter and press <Enter>.
-
- Enter a positive or negative start angle (in degrees) for
- the arc and press <Enter>, or accept the default value by
- pressing <Enter>.
-
- Enter an end angle in the same manner. Remember that the
- arc is created counter-clockwise from the start angle to
- the end angle.
-
- Indicate the center point of the arc, using a Position
- Menu option.
-
- In 2-D construction mode, the center point is projected to
- the current construction plane, and the arc is created in
- the current construction plane.
-
- In 3-D construction mode, the arc is created in the plane
- that is parallel to the current construction plane and
- passes through the center point.
