Creo Parametric - Variable Section Sweeps (Part 3 - Relations with Trajpar)

This Creo Parametric tutorial video continues the series on Variable Section Sweeps to explain how to use the trajectory parameter trajpar when writing Relations to drive the values of the dimensions in your sketch.

Hello Dave, Thank you for this video series on sweeping.
I have a question in your last example at 5:51. When you click the circular trajectory, how can you define the origin of the sketch elsewhere around the disc before clicking on the Sketch button?
In your example, your rectangle sketch is located at the vertical (at noon), but if you wanted to locate it at 45° or else, do you know how you would do that?
I went in References tab > Details button > Options tab, and I tried to change the starting point, but I couldn't select the plan or the point I previously defined...
Thanks a lot for your help!

thank you sir, may we use this trajpar on helical sweep to get variable section please reply

[@CADPLMGuy]

Great question, but unfortunately trajpar is available for Variable Section Sweeps only.

@@CADPLMGuy so what can we do to get variable section on helical sweep

Your best bet is to create a helical Datum Curve, using equation or through points, and then create a Variable Section Sweep using that Datum Curve as the trajectory. If you have a specific example I can try making a video.
