Orient squares on a curve in Grasshopper


In an architectural project, I’m trying to orient square columns on two curves and I want them to be oriented according to the curve normals on given points.

So far I managed to distribute my 0.3x0.3 squares on the two curves but they’re all oriented the same. So
now I’d like to make them “face” each other in order to have pairs of columns that I could later turn into structural frames.

The problem is, I don’t know how to proceed in order to get that orientation right.

A bit of help would be much appreciated :smiley:

Thanks a lot !

Have you had a look at the Modelab Grasshopper Primer yet?
