I’m looking for help understanding how to create an evenly distributed pattern across multiple surfaces that were modeled in Alias and then imported into Rhino and Grasshopper.
The surfaces are made up of several filleted and trimmed patches, and each surface has a different UV parameterization. Because of this, when I generate points, curves, or any parametric pattern in Grasshopper, the pattern becomes compressed, stretched, or uneven near the trimmed edges and across the different surfaces. My goal is to have one continuous pattern that flows seamlessly across all the surfaces while maintaining a consistent shape, spacing, and density.
I’m still learning Grasshopper and have a basic understanding of its components, so I’m trying to understand the correct workflow rather than just finding a quick fix.
Specifically, I’d like to learn:
How to deal with trimmed and filleted surfaces imported from Alias.
How to create a uniform point distribution across multiple surfaces.
How to align or rebuild UVs so the pattern remains consistent.
What is considered the best practice for automotive Class-A surfaces.
If anyone could explain the workflow from a beginner’s perspective or recommend tutorials or example Grasshopper files, I would really appreciate it.
From a topological point of view your polysurface is a rectangle so you could create a 4 sided surface and pull points from there to the polysurface and then use some Kangaroo magic to distribute the points.
I have another question ,the line which was made for the L0 and L1 how was it made like how the line are defined of them is it based on the surface and does it have to me equal and L1 has to be on the XY plane??
