Draw an arc by ten methods

What you'll do

Draw an arc in a sketch with the method that matches what you know: three points on it, its center, its radius, the angle it sweeps or the direction it leaves in. Values can be clicked or typed.

Steps

1. Open a sketch (see Sketching basics).
2. In the sketch toolbar, open the list beside Arc and choose a method, for example Arc: Start, End, Radius. The methods are 3-Point; Start, Center, End; Start, Center, Angle; Start, Center, Length; Start, End, Angle; Start, End, Direction; Start, End, Radius; Center, Start, End; Center, Start, Angle; Center, Start, Length; and Continue.
3. Follow the status bar, which names the method and says what to give next: click the start point, the center point, a second point on the arc or the end point.
4. Where the prompt says "or type", type a number and press ReturnEnter: the included angle in degrees (negative is clockwise), the chord length, the start tangent direction in degrees, or the radius (negative is the longer way round).
5. The arc is drawn. Arc: Continue starts the next arc from the end of the last line or arc.

Notes

• Arcs keep their center, start and end, so relations and dimensions work on them as before.
• The status bar refuses impossible input and says why, for example three points in a line, or a radius too small to reach between the two end points.
• Arc: Continue with nothing drawn says "Nothing to continue from: draw a line or an arc first."
