multibody revolution extrusion

[stefer]

Good evening to all,
I ask you for help in creating a multibody object, in this case a rubber and metal artifact.
I attach a screenshot of the drawing... in the left part I created a hot-printed artifact in one body consisting of a threaded screw and a washer. on the left side, always hot printed, a washer with a female housing consisting of a threaded compass. In the middle I have to create the rubber part... the whole is composed creating a cylindrical antivibrant type 2.
the difficulties I am encountering are related to the creation of the rubber part.. to create it quickly I thought to use the function of extrusion in revolution. . creating the profile with lines and then extruding. everything works perfectly... if not when I meet you.. In this case I did not understand how to easily follow the parts so faithfully collect the revolution. help?

Thank you!
Where are you?

inserting a sketch radius, or in your case by selecting the edge of the connection and converting it into sketch entities.
threads, if not for aesthetic issues, do not model entirely, but do the smooth cylinder and add a cosmetic thread.
