Probably has been found before, but in 401, there’s a handy trick that lets you reuse the tube primitive over and over again, very useful for making groups of cables:
- Make the first cable using the tube primitive
- When you are happy with the shape, Shift+Left Click into empty space (repeat the tool command)
- Press Ctrl+Z to undo.
- Now you have a new pipe inside your previous pipe with adjustable curve points ready to go
Hope someone found this useful
