Apply pattern to brep

[Xinrong (xin)]

Hi everyone, i want to apply this pattern to picked surfaces(black) in grasshopper, the other surfaces (green)should keep still. I have no idea to do. Thanks in advance.
this is pattern picture

i want to get it like this

search this forum for FlowAlongSrf (rhino, modelling)
and Sporph, Surface Morph (grasshopper component)

maybe a starting-point:

Pattern Projection via FlowAlongSrf

I have an interesting problem. I need to project a pattern along a surface with double curvature. The standart method is to use FlowAlongSrf in Rhino, or use the Map to Surface component in Grasshopper. Usually good enough. In my case I have a limitation. The material to be used for the test is a 2D pre-printed sheet with a pattern. In order to unroll the surface with double curvature, I need to split it into smaller surfaces, which then I mesh with a triangular mesh and turn into a brep. After…

also displacements might be an approach:

Displacement in Rhino 7

kind regards - tom

The result is a closed BREP.

Apply pattern to brep(joined by three surfaces)

Hello, everyone. As a new guy, i want to apply some pattern(example picture) on this brep which have three surfaces. Normally, we get the base surface from rhino by one surface, but i have surfaces from alias software. If the base surface is this kind of brep, what should i do, surface morph doesn’t work on brep. please give me a hand, thanks!

Thanks Quan. it’s very close to my intention. But, the new closed BREP have continuity problem with other surfaces which is what i want to avoid the most.

Thanks tom,
however, the reference you mention can’t work on my question.

Hi, Joseph, this post is created by me too. i have talk with Quan, the method he offered can’t solve my problem.
