Sketching on Reference Planes Normal to Edges

You can sketch on a reference plane, created automatically, normal to an edge.

1. In a part, select an edge and click Sketch .
   
   
   A reference plane normal to the selected edge is created at the end point of the edge closest to the selected area. The origin for the new plane appears at the edge's end point.
   
   
2. Sketch an entity such as a rectangle or circle on the plane.
   
   
   
3. Create a feature such as a boss or a cut.
