creating datum curves in space

[Skiddy]

Is there a way in pro engineer using equations, that you can create datum curves in space that twist and turn but have the same start and end point?

You can make some points in the space and after a curve that fits those points.

Sure,

I've done some pretty cool curves using curve by equation.
Try the following
Create Datum Curve use From Equation and pick the default csys and cylindrical csys type then enter the following equations.

n=5
r=5+cos(360*t*N)
z=1+sin(360*t*N)
theta=360*t

You can also combine csys and Datum Graphs to create very complex 3d curves.

Have you used UG before this can also be done but I prefer the Pro/E UI because the controlling equations are stored with the feature.

Let me know if you have questions
