I am working on a roof project and want to automate the placement of ridge tiles on selected edges of a roof. Selecting the appropriate edges I was able to master. Now, ridge tiles require a direction of placement (downwards) and therefore I want to use curves as the point givers for the instances on points node.
My problem now is: After having selected the appropriate edges of the roof (only downwards ones) the resulting curve may consist of single straight splines per edge but also of splines which represent two or more edges. Now, how can I get a spline per edge?
In the end I want all the splines to have the direction from highest to lowest vertex per edge.
