  • sweep not possible on one of my two curves

    Hi I created two curves using the spiral tool on a revolved surface. The projection of the curve on the surface of my solid worked and I was able to create one sweep. My second sweep shows me some red points tough. I do not understand what they want to tell me and how to find out what I need to create my sweep the way I…

  • Sweep on a conical spiral

    Hello, This problem is driving me crazy. I would simply like to sweep a rectangle along a conical spiral and at the same time rotate it 90°. If I use the sweep command, I can't control the amount of rotation (it can be 0° if I use lock profile direction, but it is not what I want) ; if I use the loft command, the…

  • Worm Gear or Spiral

    Hello, I'm making a helix worm like in the picture. However, there is difficulty in determining the angle of inclination of the thread. Can anyone help me? https://cad.onshape.com/documents/536e9d0ebf53bab60fc1d592/w/965b95592ae2103469fab11b/e/b53e3112cdcc919a6e378bc7?renderMode=0&uiState=6785e0cd4059a663f08e1896

  • Curve Pattern - feature pattern including full part

    Hi all, I am struggling with using Curve Pattern, maybe someone here can point out what I'm doing wrong - I want to pattern a gear tooth along a spiral curve. When I use "feature pattern" however, it looks like it's patterning the whole spiral part that the tooth was extruded on: (I first had a spiral created, and then…

  • How do I make a solid spiral on a cone with smooth transitions on top and bottom?

    Hello! How do I make a solid spiral on a cone with smooth transitions on top and bottom? I have made a solid cone with a helix on the surface and swept a triangle sketch along the helix to make the spiral, and also a solid 6mm cylinder in the middle of the cone, like a shaft. I would like to extend the solid spiral into…

  • Lofting a spiral in Z axis?

    Say I have a extruded 2D spiral like this onshape document. How would I create a Z axis twist, such as a spring, or otherwise defined by a function.
