I’m pulling my hair out on this one, because the only nodes which seem to generate frames only work on surfaces, and I’ve already distributed my points across my brep the way I want it, and both pull and closest point never seem to disregard points not on the surface, but rather throws them at the edge instead.
Can anyone help me with how to solve this properly?
I actually wonder if getting the brep normal at my points, and then getting the curve tangent at my lines would generate better planes in my case, but I’m a bit lost at how to do that as well, without flattening the trees with the curves and the points…
(Also, there’s a group of nodes in the bottom right of my grasshopper file, where I categorize the points in three sets, where I hope to be able to scale the geometry I’m placing at those points using the point index for size. I don’t know how compatible that is with whatever solution can be done for the problem above…)
Like listen bro… I don´t mean to be rude, but you have started 17 different topics in the past 48 hours all of them trivial issues, which can be resolved very fast if you take an hour or so just to watch a few basic tutorials on youtube. How data trees work is an interesting topic.
What I meant is that you need to systematize your learning curve a bit. Like learning the basic interface and especially how data trees work, ´cos they might be a bit counter-intuitive. Or maybe keep most questions you have on the same topic, then it will be easier. Anyway, I do like your progress.
Ok, so to drop some knowledge back into this thread, I did trip up trying to use my list of curves to calculate new tangents using the list of points, without really looking at how the structure of those lists looked like.
And then I discovered that luckily, I didn’t have to use my curves at all, because I already had all the information I needed in my list of points, thanks to the tangent output of the “divide length” node and the normal output on the “closest brep” node:
So now my planes are normal across the entire brep AND tangent to my guide curves!
If “distance length” wouldn’t have given tangents, I’d still be iffy about the solution, since my list of curves is a (1D) list, and my list of points is a (2D) set of points for each curve inside that list (as seen in the large yellow panels). But unless I figure that out, I think that’s going to be a new thread… sorry @davidsmavrov.
