The context menu with the right mouse button on the shaft in the system tree provides some additional options:

- “Delete” deletes the shaft.

- “Duplicate” duplicates the shaft. This is helpful if several similar shafts are needed in a gearbox.

- “Mirror” mirrors the shaft geometry and positions of forces and supports. The orientation of forces and supports is not changed.

- "Split shaft at" asks for a position on the shaft and splits the shaft into two shafts.

- "Append shaft to" appends the shaft to another shaft in the same group.

- “Export deflection” exports a \*.csv file for the deflection of a shaft. The “Result tables” in menu report also contain this information, but for all shafts instead of one only.

- “Change color” allows to change the color of a shaft.

- "Move to group" allows to move a shaft into another group. This is often used after "Duplicate".

- “Import geometry” allows an input of shaft geometry as 2D DXF or 3D STEP, see below for details.

- “Export geometry” exports the shaft as 3D STEP or IGES. Gears and bearings are included on the export.
