Drawing a Tangent Arc

1. Click Tangent Arc in the Sketch group. The tool is disabled if there are no curves or lines in the sketch plane.
2. Select the line or curve you want to draw tangent to.This is usually the end point of a line, arc, or spline, but it can be on the line. If two lines share an end point, use the scroll wheel to set tangency to the other line.
3. (Optional) Dimension the radius and chord angle.
4. Click to set the end point of the arc.The arc cannot end on its start point to make a circle or end on the same line as its start point.

The common sketch options are described in Sketch Options.
