Hi Paul,
So it's a little more complex, and I tried with the information you gave me but I can't seem to make it work, even when splitting up in different generators and changing new expressions to make it work with the other generators. Maybe I'm making it too complex for it too work. But so the problem is that the gate is going to be larger than the start and ending points, ideally the size of the gate is just the result of the start and end points PLUS some more (to define myself with a numeric value or something).
To generate the gate in the picture 1 have 2 L1S, one with the start, end and default segments, and 1 L1S for the bars in an evenly.
