Joggles

Since Sheet Metal thickness faces are thin, and you are likely zoomed out, selecting a non-thickness edge allows both edge and face Pull options. The image below shows that you can choose to pull the edge (dimmed Pull arrow) to create a new wall, or pull the face (active Pull arrow) to extend the wall. When you extend the wall, you have the option of creating a Joggle by clicking the Joggle icon in the mini-toolbar.

If you choose Joggle in the mini-toolbar , pulling the edge will create a Joggle.

On cylindrical walls, the mini-toolbar has an option to create a Curved Joggle .
