3D resultant curve from three 2D curves

[glue]

Hello to you dear ProEngineer Gurus,

Im stuck in a prety annoying situation, and Id really appreciate if any of you could give me some advise.

I have a 3D curve from point 6 to 3, ref the below image:



Im trying to redraw that curve whithout having to reference any part of it (can't use "edge" and cant use gripped points)...
I thought I could "hand draw" 3 2D curves (I do not expect a 100% fiability) and then project each other to... well I dont know yet but which would result in the expected 3D curve.

Is there any way to do it in ProE? or maybe another method I did not think about?

Thanks for looking!

if you want to get exactly this curve you can sketch from 2 views like front and right views. Use edge pick the curve, delete the curve references out of the references box to convert it to a spline that does not depend on the original curve. Do this for both front and right. Then pick both curves->edit->intersect to get the 3D curve that exactly matches the orginal but is not a child of it.


If you dont want to do this then you can do much of the same but sketch 2 splines from the front view and one from the right view that closely approximate the curve and intersect those 2 curves.

Thanks for your reply csusie, I didn't know you actually could remove the dependency of a curve! Thats a revolution now for me as I had a whole bunch of sketches that fits the same problematic... Will try again tomorrow following ur guidelines, Thanks a lot!

It works like a charm! Rocking!
