Tube

The Tube is a generalized extrusion made up of two curves:

• Axis curve - set from Assembly/Create/Axis
• Section curve - set from Assembly/Create/Section

Both of these curves can be set from their menus to curve primitives or Free drawings.

If both Axis and Section are primitives, the resulting shape can be directly placed in the scene, just like basic Primitives.

If Axis is set to Free then you can draw a complex tube with the current Section (Free is not yet supported for Section).

These curves can be sculpted separately, with their own local symmetries: W toggles between Axis/Section sculpting.
