I’m currently working on a project where I need to create a uniform mesh layout on a model, and I’m facing some challenges. I’ve tried using the ‘Drape’ command to create a mesh surface, but I’m encountering an issue with jagged textures appearing in the vertical direction. This is especially problematic as I need to fill undercut areas with a consistent mesh layout.
Here’s what I’ve attempted so far:
Using ‘Drape’ to create a mesh surface over my model.
Adjusting the drape settings to try and minimize the jagged effect.
Despite these efforts, the vertical jagged textures persist, and I’m struggling to achieve the smooth, uniform mesh layout I’m aiming for.
I’ve attached an image showing the current results I’m getting with the ‘Drape’ command. As you can see, the jagged textures are quite pronounced, and I’m not sure how to resolve this.
I would greatly appreciate any advice or suggestions on how to improve this situation. Specifically, I’m looking for ways to:
Reduce or eliminate the jagged textures produced by the ‘Drape’ command.
Achieve a more uniform mesh layout, particularly in the undercut areas that need filling.
Thank you in advance for any help or insights you can provide. I’m eager to learn from this community and find a solution to this challenge.
Shrinkwrap V0.gh (1.4 MB)
ShrinkWrap is a feature of Rhino 8. If you use the lower version, then try Dendro, they are the same.
Blender is better choice of processing mesh work like this.
Thank you immensely for the effort and the solution you’ve provided. Your contribution is greatly appreciated, and the version you’ve created has been helpful in advancing my project.
However, I must emphasize a crucial aspect of my initial request that might have been overlooked in my earlier post: the need for effectively handling undercuts and demolding in the mesh layout. This aspect is vital for the success of my project. Filling the undercuts with a uniform mesh and ensuring smooth demolding are key challenges I’m facing. If you have any insights or further suggestions on how to tackle these specific issues, it would be incredibly helpful.
Once again, thank you for your valuable support. Your assistance has been instrumental in moving closer to the ideal solution I’m seeking.
I understand that you are creating a mould so Drape is useful because it doesn’t create undercuts, correct?
Drape seems to project the vertices of the mesh at the object to drape over so where there are large vertical areas (in the direction of drape) then you get long mesh edges where some vertices “drop over the edge”
You could take the output Mesh from Drape and run it through Grasshopper’s TriReMesh or QuadReMesh components. be careful that this doesn’t introduce tiny overhangs again though. This will all depend on the resolution of the drape mesh and the Remesh components.
You are correct; I want to generate a solution for stamping dies using Grasshopper. Therefore, I need to remove the inverted portions from the model. To achieve this, I have used the “drapes” command to cover these inverted areas. However, as you mentioned, the accuracy of these draped grids is poor, and the inverted portions may not necessarily be located at the edges.
Wow, thank you so much. I tried to download the gh script, but I got stuck on installing the pOd Pick VEF plug-in. It always prompted me 404 not found for this component, while other components could be downloaded normally.
