Better way to create sections along a curve?

Hi I’m trying to make circles on selective curves and have them oriented with the curve. I just started GH so I’m not exactly sure the best way to go about it… I also need to set the radius of each circle if anyone has some suggestions I would greatly appreciate it.

Thanks!

My choice for such a task would be Perp Frame

As for different radii of the circles, you would need to define some rules, or you could use one slider for each radius which kind of defeats the purpose of a parametric modeler.

Hey thanks Lando that looks good! I think for radius I will try to set value for first and last circle then have then have the rest interpolate between those values.
