Hi all,
I'm trying to record the endpoints of the drawline() function in an array so I could record the distance. Is there a way to do this? Or is there a better way to draw a line and record the endpoints' coordinates/ calculate the distance between the endpoints?
Thanks!

I grok that if search local installed doc, but in the online search as well? That truly sucks if they've done that on purpose.

Well, I don't know why didn't yesterday; today it did return the function reference...maybe something was momentarily offline yesterday when got the failure...

h = drawline();
ep = h.Position;
x1 = ep(1,1); y1 = ep(1,2); x2 = ep(2,1); y2 = ep(2,2);
