10% SLOPE RAMP GENERATOR FROM POPULATE 3D POINTS (ANEMONE LOOP)

Can anyone help me figure out what I'm doing wrong?

I'm trying to create a 'ramp generator' using points & lines.

The goal is for the loop to pass through as many points as possible to create a series of ramps with slopes =< 10%.

Here's my pseudo-code:

1. Populate brep with random points

2. Sort points by Z values

3. Draw line from point '0' of sorted points to all other sorted points

4. Project lines down to plane of first point and cull all lines =< 5.7 degrees (10% slope)

5. Sort remaining lines by length and return line with the largest length (what I want)

6. Cull all points used to create lines =< 5.7 (step 4)

7. ??? now, I want to somehow pass remaining points from step 6 back into the loop and return the next curve that is: the largest length curve from all curves =< 5.7 degrees

I've attached the script

Thanks ya'll!

Something like this? Anyway, how does this help in real situations?

Thanks! I've been tinkering with it...It should be something more like this

You see anything that can be optimized?

I'm developing a rhetorical space where ground planes are =< 10% (aka the max slope for driving a forklift)

Its just the first step of ongoing exploration.

You may find the same fix in the file I posted earlier. Nevertheless, I don't know if I should fix it for you.

I'm not sure if this is what you are after, but check it out. Modified parts are marked in red.
