    Having trouble designing a spring. What am I doing wrong?

    Valentina Tina

      Hello.

       

      I'm fairly new to CAD, but I know most of the basics.

      I am trying to design a spring with 2 inefficient revolutions (1 on each side) and 9,5 efficient revolutions - 11,5 total. Firstly I sketched a circle with a dimension of the middle diameter of the spring. Then I created a helix with a variable pitch/rotations (the height of the spring matches the desired height), and a circle piercing the helix. When I try to create a sweep boss/base I get an error saying 'the sweep operation failed to complete'. I'm guessing the thickness of the circle is too big to complete the sweep.

      I am attaching a file of my helix sketch.

       

      Could someone please help me design the spring?

       

      Thank you in advance!
