Graphical Editing of Shells

In the 3D window, the editable profiles, axes and extrusion vectors are shown in a different color, so it is easy to find them.
Note: You can change this color using the “Reference Lines in 3D” setting at Options > Work Environment > Selection and Element Information.
An Extruded Shell has a profile and an extrusion vector; both are editable.
A Revolved Shell has a profile and an axis.
A Ruled Shell has two profiles, on any two planes, connected by the Shell body. The profiles can be edited and rotated. You can also rotate either or both of the profile planes.
