Place families on Point arrays on surface

Hi Jacob/Nick

Thanks for all your guidance.

I have managed to place the family on the points.

Can you please advise what nodes/workflow I can introduce between selecting the surface and defining the X/Y/Z coordinates of the first point (A range follows as per ‘step’)

Currently I ‘Watch’ the X/Y/Z list that the surface node picks and I manually put that ‘data’ numbers and connect to the point.bycoordinate node.

I tried using this workflow but got a bit confused on the hierarchy…

The next challenge I have is controling the ‘normal’ of the point to give some families an angle after placement! Any tips?

Thanks,
