Going cross eyed trying to figure out the logic on this, I know it’s probably simple. I have this cable net below, supporting a grid shell. It’s just hovering right now but I’m going to add the kingposts next.
I created it sorta manually by duplicating components but for this assignment it has to be adaptable to any number of ribs and any form. Meaning I need to trim this monster down and make it truly parametric. I’m guessing a Series and List Length comes into play, with clever list management but I haven’t quite added up the solution yet. Would appreciate a shove in the right direction.
Attaching a simplified GH with internalized curves. I’m using Intersect Curves from Paneling Tools but that prob isn’t necessary, it’s just what I started with.
Haha, sorry. I have so many plugins it’s absurd. I forget what I am grabbing from via the search bar.
To answer your question, naïve sure, but not humble so much as self deprecating. I’m studying parametric design at a university now but I’m mostly self taught, I have blind spots and bad habits so I am embarrassed about asking questions I perceive might be simple, that I should already understand having worked with Grasshopper for years.
So this surface is a big pain in my ass, as it was intended to be. With the mix of curvature directions, the net is clipping through the surface, also useless in some areas but imma not worry about that yet. I’d like to explode the net into segments, test each for Curve Surface Intersection and Cull. Do you know of a component for testing that? I was trying to adapt Curve | Surface but it seems like a convoluted journey, working from intersection points to true/false results in the same tree.
It gets better or worse depending on the Net Offset.
For reference btw, this me trying to recreate and adapt the building systems used on the Taiyuan Domes. Still a long way off obviously, I’m just trying to approximate the cable nets that support the grid right now.
Not the solution I was hoping for, a Band-Aid but I targeted the problem children using a Point List and Cull Indexed them. I’ll get back to this curve/surface intersection thing another day. I found a promising plugin on Food 4 Rhino but the zip is reading as invalid.
