Keypoint Curve Tools > Arcs > Concentric Arc
 
 
 

Allows you to create a keypoint arc concentric to another keypoint arc.

To draw an arc concentric to another arc

  1. Click the Arcs > Concentric Arc icon, or choose Arcs > Concentric Arc from the Keypoint Curve Toolbox.
  2. Click the arc from which the new arc will be offset.

  3. Click the start point of the arc, or type a 3D coordinate to place the point exactly.

    As you drag the start point, the Concentric Arc tool displays the distance between the two radii.

  4. Click the end point of the arc, or type a 3D coordinate to place the point exactly.

Tips and notes

Concentric Arc Options

Degree

Specifies the degree of the curve. The values range from 2 to 7. The default is 6.

Spans

Specifies the number of spans in the curve. The values range from 1 to 14. The default is 1.

NoteThe sum of the degree and number of spans cannot exceed 16. When creating rational geometry, as set in Preferences > Construction Options , the Spans option is not available.
