Thank you very much.Good morning.
you can use bouncing command
next time make a step to present yourself in the appropriate section new users.
other thing to use the inventor section to have more visibility for inventor users and not in general design to ask moderators to move in the correct section
Thank you, I'll try.hi in these cases I used the helical command with round profile extrusion in size and mirrored version with symmetry plan on the middle of the length of the bushing, in my case I needed to pass oil to facilitate the flow , basically they would be two cross spirals
