Hey,
I have a bunch of curves with points and trying to get the start and end of each one.
i@neighbours = neighbours(0, @ptnum);
This gives me a list in an array with some with two values and some with one
etc…
how would I filter only the ones with 1 value in the array? Delete sop for example?
Thanks!

You can use the neighbourcount function and group the ones that return 1.

Hi,
you could also set the attribute wrangle to Primitives and run the following:
This gives you a primitive attribute for each curve containing an array with the start and end point numbers of that curve.
Hope this helps,
Andy

int i[] = primpoints(0,@primnum);
int start = i[0];
int end = i[len(i)-1];
i[]@start_end = {};
@start_end[0] = start;
@start_end[1] = end;
This gives you a primitive attribute for each curve containing an array with the start and end point numbers of that curve.
Hope this helps,
Andy
