and the edge you choose to modify, neighboring lines are
extended or trimmed, and new lines are added, as necessary. change the shape of the perimeter of the profile or its rings
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
