Problem with B-spline helix

[chrisb]

I have created a Helix for a spring with Macro FCSpring Helix Variable. The helix looks very good, but if I create a sweep with it, it looks rather garbled.

Is this an issue with B-spline or with the sweep?

Seems like it's time to get engaged with Curves. I havent found the time yet, but whatever I see here in the forum looks great.

hi

the problem with my macro is : i cut the conference in x points (default 72 points (max 360 points)) and with the formula (as UR_) much more points and the point to point connection are shorter
