Rebar link problem

[Yna_Db]

Select surfaces at both ends of your element (it should be easy since they have the smallest areas), create points in the middle with Surface.PointAtParameter (U and V to 0.5), join these 2 points with Line.ByStartPointEndPoint, and finally place your circles like shown in the post below (but probably using Curve.NormalAtParameter instead of Curve.TangentAtParameter):

Rotate family after insert along curve to the tangent

To all useful ends, I’ve written something quite simple that works with regular curves: [image] [image] I created little circle faces along tangents to place instances on thanks to Springs node. For the moment, I can’t divide a spline equally, but there’s probably an answer to that somewhere (?)…
