sweeping one end
sweeping one end
(OP)
Hello
How can I sweep or pattern a straight line along a helix, but keeping one end of the line fixed in the origin?
In the picture I've shown just two "instances" of the pattern, made by hand.
I've tried pattern along but it gives strange results
I've also tried pattern with rotation using the z-axis but the "loose end" of the line doesn't keep it's constraints to the helix.
I cannot figure out how to do generate a sweep with that shape.

If this is something you may be doing frequently, it wouldn't be that hard to write a simple program to automate this workflow.

I've got it with "Studio Surface" but maybe there exist an simpler way.

What version of NX are you running?

mmauldin,
this is the same surface I've got with "Studio surface" by using the same parameters that you used with "Through curve mesh" but you also used a point as primary curve. I had to "switch string" in order to get it.
Is it advised to use "studio surface" or "through curve mesh"?
What if I want to get several lines instead of a surface? (like my first picture) without programming?
regards

And then intersect that planes with the above surface.
But that way I cannot control very well the curve spacing along the spiral.
