      hi guys I've been experimenting with the helix tool for making threads with a bit of success, but I'm trying to draw a internal trapezoidal thread ( diagram 150mm, pitch 2.7 mm, depth 1.3mm , 20mm high)
      could any one help with a walk through on how to do this

          Model in meters to avoid issues with faces below 1mm. Afterwards scale it down to correct dimensions.

          If you are using Helix Along Curve you are 90% there.

          If you have CurviLoft you can use Loft Along Path to extrude the profiles.

              Try sharing a file because I honestly can't make much sense of your dimensions.

              A 150mm [diameter?] with a 20mm height seems wrong.
