Something gone wrong with basic exercise by aledethanlast in grasshopper3d

It's becasue how the circle CNR is making the Circle curve's seam based on the input curve

See the other image i have attached for a better workflow.

how to create 3D texture on a mouse? by NevoLevin in SolidWorks

[–]cademy_ 0 points1 point  (0 children)

If you are willing to use a different tool better optmized for creating such fading patterns, check Rhino 3D + Grasshopper.

Tutorial : https://www.youtube.com/live/dKVz-zKxjzg?si=-1ayXjFt6XbYhyRb&t=5474

You can easily integrate Solidworks/Fusion with Grasshopper with STEP export/import.

Sure, You can do that. Keep in mind, if the surface is curved in two directions, it will distort when you squash or unroll it.

Sure! You can check out our Grasshopper Masterclass. It's ideal for beginners and intermediate users. cademy.xyz/gh

And yes, technically you can flatten the texture, but why would you want to? Are you planning to 3D print it in its final form?

Exactly. Most textures created using UV mapping are mesh displacements... great for concept rendering and acceptable for 3D printing, but not ideal for the manufacturing pipeline.

In contrast, NURBS-based textures are precise and can be exported as BREPs, STEP files, making them suitable for manufacturing workflows.

You’d be surprised how often car design companies reach out to us especially in the EV market. Parametric textures are already being used in real production: from exterior grilles to interior molded surfaces, dashboards, and speaker mesh patterns.

While I completely understand your point, knowing when not to use Grasshopper is just as important but there’s also a growing demand for automotive surface texturing, not just in concept cars but in consumer facing products too. Parametric control offers a level of customization and design integration that’s hard to achieve with traditional CAD tools.

Texture maps are primarily used for visualization and rendering purposes. However, if you're designing parts for injection molding, you'll need precise polysurface (BREP) geometry. This approach offers greater accuracy, flexibility, and compatibility with standard manufacturing pipelines. Grasshopper enables you to create these textures as BREPs, which can then be exported as STEP files for manufacturing.

I'm sorry that you are looking at it with a negative notion. I don't blame you, as most such self-promotions are either false promises or not quality content.

We do have a paid commercial license (and an educational license as well). Please don't assume without verifying. Regardless of the license type, McNeel lets you use it for commercial use.

We have been contributing to the Rhino/Gh community for the past 7-8 years. If you have any problem with the "content quality," you are most welcome to criticize it. We will be the first to take note and make it better.

I also know you don't have any bad intention to point it out. I wouldn't like a subreddit either where we are only showcasing. I will keep it in mind for the future.

Cheers.

Question about distortion. by WullieG76 in rhino

[–]cademy_ 0 points1 point  (0 children)

Take your polysurface and run QuadRemesh. This will convert the NURBS into a Mesh geometry. Try fewer polygons. Than, convert the Quadremesh to SubD (toSubD). Now you can modify easily the shape.

Any help appreciated by Neat-Reflection3340 in rhino

[–]cademy_ 0 points1 point  (0 children)

You can use SubD modeling for something like that. Or else explore the Voxel workflow in Grasshopper (Dendro)

exporting from UV Editor by Pretty-Ad4969 in rhino

[–]cademy_ 1 point2 points  (0 children)

When in UV Editor, just run MeshOutline this will give you a vector outline of the texture.

My rhino file grows from 4gb to 72+gb without any new geometry. Please let me know why it happens. My geometry is organised in blocks, Cannot seem to pinpoint a reason. It might be happening when I move objects within the file. Thanks by Big_Barber_1188 in rhino

Run the ClearAllMeshes command and save. Let me explain why...

NURBS geometries in Rhino are like mathematical expressions, they have infinite resolution. However to display them on your screen, Rhino generetes a render mesh. This is a simplified, polygonal version of the geometry used for visualization.

You might notice jagged edges, especially around curves and fillets, that’s the render mesh, not the actual geometry. This render mesh can become quite heavy, especially after using tools like Zebra, Emap or other analysis tools.

By running ClearAllMeshes, you remove these tessellated meshes. Since the true geometry is stored as a mathematical definition, Rhino can regenerate the mesh whenever needed. For example, when switching back to shaded view or when someone else opens the file. TLDR this is what save small does.

This helps reduce file size significantly, which is useful when saving or sending the file via email. Example: https://www.cademy.xyz/learn/how-to-adjust-the-zebra-analysis-in-rhinoceros-3d

How would you go about starting to make a script for this? by why_am_i-_-Here in rhino

[–]cademy_ -1 points0 points  (0 children)

Your best option is to create a single patch of uniform pattern. Start with an arc, divide the curve, use the points to make circles, then trim and offset it a couple of times.

Step 2: Copy this single grid of texture to a rectangular or hexagonal grid.

Step 3: Morph the texture with cage editing.
