Use this procedure to change the area of an extrusion mass element using the Edge grip.
The Edge grip has three edit modes: Offset, Add Vertex, and Convert to Arc. The default mode is Offset, which offsets the selected edge in a direction that is perpendicular to the midpoint of the edge. Depending on the shape of the mass element and the edge you choose to modify, neighboring lines are extended or trimmed, and new lines are added as necessary.
Use the Add Vertex edit mode to add a vertex to the selected edge, and create a new edge. If the selected edge is an arc, the new edge is an arc, as well.
Convert to Arc changes the selected edge to an arc and stretches the midpoint of the edge. The edge grip for an arc also has a Stretch mode, so that you can stretch the midpoint of the edge after it has been converted to an arc.
You can also change the mass element area dimensions on the Properties palette.
