How to model a curved spring

Let me show you how to use some surface commands which combine in a 3Dsketch for the solid sweep.
No coil command needed.

  1. Step 1: 1st sketch



  2. Step 2: drawing






  3. Step 3: 1st surface sweep



  4. Step 4: 2nd surface sweep


    The 40 coils account for the twist.

  5. Step 5: 3D intersection curve



    Start a 3Dsketch and define the intersecting geometry with the surfaces.

  6. Step 6: workplane


    Create a workplane normal to that curve at any endpoint

  7. Step 7: final sweep


    create the solid sweep.

  8. Step 8: video
