Help Line Arc

Create a help line arc.

\harc

ARC+ offers three methods to create a help line arc:

By three points - first, second, third

By three points - first, third, second

By Center, point and angle

Creating a Help Line Arc through three points - first, second, third

Define the three points:

The starting point of the arc

A point anywhere along the curve of the arc

The end point of the arc

A help line arc passing through the three defined points is created.

Creating a Help Line Arc through three points - first, third, second

Define the three points:

The starting point of the arc

The end point of the arc

A point anywhere along the curve of the arc

A help line arc passing through the three points is created.

 NOTE The three points define the plane on which the arc is created.

Creating a Help Line Arc by a Center, Point & Angle

Define the center of the arc and the starting points. Specify the arc angle measured counterclockwise from the imaginary radius that connects the center of the circle and its starting point.

The last angle appears as the default when you create additional help line arcs. The help line arc is created parallel to the current working plane.
