Thank you very much, awesome example. exactly what i was looking for.

OK, i found a solution that works.

still the question is: is there a better solution, especially for defining a starting point on the edge.

Currently the starting point is defined by the lowest point number per edge and you could move it by playing with the first u/v values of the animating carve, but it would be a pain.

The tutorial:

File attached, if you dive into the two foreach nodes, you'll see what i mean, i made one similar to the tutorial, and one how i (as a total houdini noob) would expect it to work.

Thank you for your help
