Arc
left clickThe Arc command draws an arc with options for a center location, one end point, and a second end point or an angle.
Insert an arc
Steps:
- Pick the center of the arc's radius.
- Pick the arc's first endpoint. This point is also the arc's start point.
- Pick the arc's second end point, or type an angle.
Arc
Command-line options
Default
Draws an arc starting from the center of the arc's radius.
- Tilted
Draws an arc whose plane is tilted from the current construction plane. - Length: Sets the arc length as measured along the arc. Type a positive or negative number, or pick two points to specify the arc curve's length.
- Midpoint: Draws an arc from its midpoint.
Deformable
The Deformable option draws a NURBS approximation of the arc with a specified degree and number of control points.
- Degree Specifies the degree of the arc. When drawing a high-degree arc, the output curve will not be the degree you request unless there is at least one more control point than the degree.
- PointCount Specifies the number of control points.
StartPoint
Draws an arc starting from the first end of the arc.
- Direction Specifies the direction of a line tangent to the arc's start point.
- ThroughPoint Specifies a location the arc curve must pass through.
- Center Specifies a center point for the arc's radius.
Tangent
The Tangent option draws an arc tangent to selected curves with options to pick a point not on the selected curves or to specify a radius. Each prompt allows you to pick a point that is not on a curve for the arc to pass through. At some prompts, the option to enter a radius appears.
- Point The Point tangent option appears for each prompt. It releases the command from the tangent constraint for that pick.
- FromFirstPoint Forces the arc to go through the first picked point on the curve instead of allowing the point to slide along the curve.
Extension
Extends a curve with an arc to a specified end point.
- Center Extends a curve with an arc by from a specified center and end point.
