Automated Linear Frame Growth Issues - Hoopsnake Mirroring

Hi Grasshopper community,

I'm recently new to the program but I come here often to read and then use it as much as much as I can to learn because its awesome! I had come across a hoopsnake mirroring script that and I attempted tweaking it for several days but I'm having problems achieving the full idea i had.

Problem 1:

Once I Brep a frame of the original cube, and the hoopsnake starts, it does not always select the right face of the frame, sometimes chooses a face inside rather than the exterior one, therefore not always fitting pieces together nicely. I tried applying a bounding box to each frame and use the face of the bounding box as reference for the hoopsnake mirroring but I couldn't figure it out so i got rid of it. So I'm stuck...

Problem 2:

The other thing, is I'm wondering whether its possible to parametrize some sort of structural principle into the linear growth sequence in order for structure to retain realistic structural integrity. For example, when you start hoopsnake, the cube linearly grows (mirrors itself) towards the selected point(s); if the growth goes up and across, how would I make it reach a structural limit to make it go back down to the floor and back up again and continue? Could even be as simple as "after 5 frames/cubes vertically and across it goes back down and then up again towards the referenced point(s)" or something.

PS. "Reset All" in Hoopsnake before doing anything.

Hope someone can help.

Thanks in advance,

Cesco
