Helical groove

2D plans Layout

Hi all

I have a small problem with SolidWorks and the drawing axes
I make a lifting drum, and on the drawing the grooves of this "thread" with a circular profile do not allow me to put axes, or one out of two!
I take the right orientation, I put the trajectory in line with the profile. But nothing works

I have differences between the profiles

I work with the skeleton method, but I managed to do it on other software like inventor without any problem.
So I redid a part without the method with the same dimensions, and there it works :sweat_smile:

Same size, different design method, and different result but I don't explain it. Do you have an answer? A solution?
Possibly with a winding and subtraction of the bodies :sweat_smile:

I'll give myself the solution.
Apparently, external projections create a lag.
I got the profile and the axis references as an external reference, and I created the helix directly in the room, which I recovered before in a 3D sketch by projecting the entities.
