Keypoint Curve Tools > Circular Arc
 
 
 

This tool enables you to specify a circle by first placing its center point, and then clicking to indicate a point that lies on the curve.

To draw a circular arc

  1. Click the Arcs > Circular Arc icon, or choose Arcs > Circular Arc from the Keypoint Curve Toolbox.
  2. Click the center point of the arc, or type a 3D coordinate to place the point exactly.
  3. Click a point to lie on the arc, or type a 3D coordinate to place the point exactly.

    As you drag the circumference, the Circular Arc tool displays the radius of the circle in current linear units.

Circle 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.
