Sketch an arc by defining center, start, and end points.

  1. Click Center point arc feature tool icon.
  2. Click a center point on a sketch entity.
  3. Click start point.
  4. Click end point.
  5. Optionally, immediately after the arc is created, input a numerical value (or type "=#" to input a variable) for the radius and press enter. This dimensions the arc without having to use the dimension tool.

To input a variable in any dimension field after the geometry is already sketched, the equal sign (=) is not required. Type "#" to input a variable.

See the Learning center course Introduction to Sketching (Onshape account required) for more information.
