( ͡° ͜ʖ ͡°) OK, all you wizards out there in the CAD world. I need to draw a spiral but do not have a clue on how to do it. or even how to start it. I have searched the forums without success. I need at least 50mm distance between the walls as it spirals down to the center. This spiral is housed in a 350mm cylinder that is rotating to move material to the center of the said cylinder where it will be discharged out. Any suggestions will be greatly appreciated.
