Select last point in a line for transform

[anicg]

How do I select the last point in a line to transform it, I can do it manually but it will hardcode number 19, I may need to change the number of points and still keep that last point selected for transform.

This point wrangle will create a "last_point" group with the highest number point:

if (@ptnum = @numpt-1){
    setpointgroup(0, 'last_point', @ptnum, 1, 'set');
    }

Transform the last_point group then. Could be even simpler in group expression.

if you have several lines, you can run over primitives in a wrangle

int primpts[] = primpoints(0,@primnum);
setpointgroup(0,"last",primpts[len(primpts)-1],1,"set");
