Transformation of a polygon tunnel

[Joseph_Oster]

Here it is. Looks like it uses Anemone:

Bend polyline progressively with slider

Your model was way too complex for me to follow. My first effort (purple group below, polyline on the left) is not the droid you’re looking for… The second attempt (white group, polyline on the right) uses Anemone and is better since all the segments are equal length, as I intended. [bend_polyline_2019Oct1a] bend_polyline_2019Oct1a.gh (25.7 KB) If your polyline input has arbitrary length segments(?), it won’t do either, but the Anemone group could be adapted rather easily by replacing the …

And on the same page:

Bend polyline progressively with slider

I like this one much better. The white group (“bend it”) at the bottom does the heavy lifting with Anemone. It has two geometry inputs: 1) a polyline and 2) a rotation plane (‘rot_plane’). The ‘angle’ slider sets the rotation angle that applies to all segments. The first three groups are optional: ‘Consruction Plane’ (light blue) with Azimuth and Altitude sliders. ‘line’ (purple) that sets the origin and total length of a line. ‘polyline’ (yellow) with a ‘Count’ slider to set the number of…
