A Problem on the adjustable screw

Hi all

Can anyone tell me how to create the adjustable screw in Pro-E? Does anyone know how to do this now.

Here is the Annex.

I look forward to hearing form you.

    Just another view to show how this correlates with your definition. I also noticed that I had a RH screw; yours is LH. So, a change of the theta definition from t to -t was also made.

    Have you tried using a helical sweep with a variable pitch?

    Yes,I do. But the dimension is different from the label above the dimension of cad drawing.I do not know where the error.

    Looked at your DWG quickly. All the note text was unreadable for some reason, but I could read the drawing. Looked to me as if this was a 2D-only design, because it didn't really look like a view of a full 3D model, yes? If I understand correctly, the spiral is a thin blade of a tapered auger. It also looks as if its section is tapered. As to the variable pitch, the way the drawing is dimensioned doesn't really tell me what's going on. In other words, the pitch could suddenly change to a new value at each of the dimensioned positions (360 degrees of revolution)--which I doubt--or it could be a continuously variable pitch that yields the dimensions shown. Can you clarify this a little bit more???

    Is this the sort of thing you are trying to do?

    Do you measure the pitch of 3D model Between the pitch of CAD drawing?They are the same pitch it?

    Here are some images of a model created with a variable pitch helical sweep.

    Can you show all of the pitch in 3D model?
