- In Sketch mode, on the ribbon Sketch tab Draw panel , click Arc Tangent .
- Select the starting or ending point of a previously drawn arc.
- The first value input box highlights. Enter a value for the arc radius, and press TAB. The field displays a lock icon to indicate that the value that you entered constrains the cursor.
- The second value input box highlights. Enter a value for the included angle, and press ENTER.
Note: If you press ENTER after you enter a value for the arc radius, you cannot specify the included angle. The angle of the arc is drawn using the current angle of the cursor instead.
The arc is drawn tangent to the previously selected arc and dimensioned automatically using the values you entered.
