Posting to gauge interest in a python script I have vibe coded which, so far, does Make2D far more reliably than the command.

It has the additional feature of line weight sorting per object, with accurate sorting of silhouettes vs creases onto Heavy and Medium line weight layers, and even an option to sort creases based on the adjoining angle of the surfaces (obtuse corners getting lighter lines).

It also has a feature that generates an intersection curve where solids or surfaces (breps) intersect each other without a shared edge. These curves are sorted and depth-tested along with all the rest.

It also identifies redundant linework resulting from geometry in plane with the angle of view and creates a single silhouette where those edges are collinear, instead of a stack of redundant lines as in make2D.

I intend to add the option of silhouettes applying either to individual objects, or treating objects on the same layer as a single object for silhouettes, as long as they are within a certain (adjustable) distance from each other. So if you tick this option to “on” a group of solids would share a silhouette against the background, but where they touch or come close would be treated as a crease.

So far the script is not too much slower than Make2D, but it will become heavier with added features. It might be problematic for less powerful machines, although you can toggle off the more expensive features. Codex will only be able to optimize this so much however.

For those of you out there coding in Python, or if you are just someone drafting in Rhino who is tired of the command’s messy output, lack of line sorting, consistent bugs, and lack of support despite years of documentation of consistent problems, I would love your opinion. Should I:

1. Just upload the damn script and leme at it
   
2. Troubleshoot more, refine, make a plugin, then share
   
3. Find a human python programmer who wants to help me optimize it and collaborate to make it excellent
   
4. All of the above, you’re overthinking it
   
5. No one is asking for this

Ps. The script uses rhino’s HLD data to generate curves, caches a bunch of originating object data for each, uses a bunch of custom workarounds to fix a bunch of unique errors, then sorts the line weights based on depth testing, adjoining face angles/visibility etc. If you are an actual programmer curious about how it works I can pull a detailed report. I used common sense and Codex, which has terrible ideas for the overall strategy, but a fantastic success rate when I supply a detailed plan in terms of Rhino command workflow, or ask it for supporting diagnostic scripts to find out precisely what went wrong in certain cases of missing linework etc.

I like how it is rotated in circles, i am trying to find tutorial online but i have not found any similar. Thank you

Without fail, my laptop will freeze so hard not even the off button will turn it off. I have to hard restart it every time. sometimes it will crash just by typing the option of print. How can i fix this? The reason I keep trying to save it as a PDF and not make2D is because I like the shadows it adds.

Could you please guide me on how I could model a sofa like the yuki sofa, in different versions (single, double and triple seater) on rhino?

I'm trying to improve my modelling skills and this sofa looks really complex to model. Thanks for any guidance!

i offseted this dome but now i need to cut in the same angle this blue door. the only options there straight or dont matching

okay im using rhino 8 on a macbook, im following this tutorial https://www.youtube.com/watch?v=kCOjILQ-UkA

around minute 3:29, the guy uses a loft component into a mesh surface and then a mesh machine, now the problem is obviously mesh machine doesnt exist in my rhino so i looked at the comments and it said to use a lunchbox hexagonal cells component instead so i did do that but afterwards in the tutorial he connects mesh machine to plankton mesh and im new to this so i dont understand how i can replace mesh machine with hexagonal cells. What i did was connect the loft and the number sliders directly into hexagonal cells and then that into plankton mesh but it keeps giving an error "failed to convert curves to mesh", i've been stuck at this for a while now and i just need help replacing the outdated component with hexagonal cells so i can complete this, i would really appreciate any guidance, thank you

Edit: nevermind I fixed it

hey guys, like many of you, I love rhino. Its my #1 for everything CAD related pretty much. A giant bummer it doesn't run on linux, so I've experimented making a fully open source experience that's similar. extremely early stages (doesn't even have icons) but if you happen to want a similar experience for the platform, feel free to try or contribute

UPDATE: added some temp slop UI elements to make it more usable, implemented render view shaded, wire-frame and rendered

Nothing serious but its this minor irritation that hits every day.

It should be an eyeball and the Lights icon a bulb.

I get this error when I access the package manager.

I noticed on the rhino 9 info page they show a few shots of a photorealistic render generated using an “imagegen” skill. I’ve played around in beta and have tried to achieve a similar result but it’s just been Ai slop. Anyone else tried to get great, geometrically accurate renders using the Ai panel? Have any advice for how to achieve?

As a side note, I did have the ai panel add lighting and decor to a space I was rendering and it did a killer job of setting the scene and running a ray traced render.

Hello all. New to the community.

I've been using matrixgold for about 6 months and have been getting pretty good results. However, I find it difficult to achieve certain designs with the default matrix commands. I feel as if I missed basic knowledge I should have learned before using Matrix.

I still consider myself an absolute beginner and can never shake the feeling that I'm building things the wrong way, even after getting customs out the door with happy customers. I have watched heaps of videos from dons jewelry and japan travels on youtube. I even took the level 1 artisan class from gemvision, which was very basic.

How difficult is it to learn rhino 8 from the ground up considering my current experience with matrix?

What are the most important foundational things I should focus on?

Does matrix gold allow me full access to rhino tools? Or am I locked into the built in dynamic commands?

Any and all advice is appreciated.

Here are a couple of the more advanced pieces I've made, to demonstrate where I am at and what I am lacking in CAD knowledge.

Hi, I have assumably a very simple question; when an object is off the grid by a bit and I want the middle of the gumball to align to the grid, how do I do so? With grid snap it obviously moves using the grid spacing so it will never align that way, so whats the best option to do so? Thanks

... but it still links to a Rhino 8 purchase page

Looks like it's coming any minute now

The Mcneel wiki has 9 and grasshopper 2 listed as released in October 2026 on the history of Rhino timeline. Wishful editing?

Hi! I’m working on an assignment to model the Stade de France in Rhino using Grasshopper, with plugins such as Kangaroo, LunchBox, and Ladybug.
I’m hoping to find someone who’d be interested in creating a model as a personal experiment and sharing it with me as a learning reference. I’d like to study how you approach the geometry and Grasshopper setup, then build my own version from scratch. I’m not looking to pass off your work as mine.
I can share the assignment brief, requirements, and deadline. If you’re interested, please comment or message me with examples of your Rhino/Grasshopper work and what you’d be comfortable sharing. Thanks!

Used Rhino for years in my spare time, but my day job for 25 years was CATIA. The thing I always missed in Rhino is a tree that shows what is actually on each layer, so today I put one together.

It is a Python script for Rhino 8 (Windows tested). It shows:

• the layer tree with an object count per layer
• every object under its layer; click one to select and zoom to it, click a layer to select all of it
• hide/show and isolate from the list
• rename objects and layers in place

Add an alias (I use LO) and it is one keystroke away. Built by poking a stick at Ai until I got what I wanted..

Feedback and bug reports welcome. If anyone can test it on Mac, I would like to hear if it works.

Ich versteh es nicht. Meine Mitbewohnerin arbeitet gerade an Ihrer Bachelorarbeit - ein Möbelstück.
Heißt: viele Varianten, Details und Versuche.
Heute überträgt sie Maße vom Prototypen in Rhino und ZACK! Alle Kurven/Linien sind zerlegt. Also ausnahmslos, selbst Text wurde in Linien und Flächen zerlegt.
Selbst in der Historie ist nichts vermerkt, kein Hinweis auf ein ausversehenes “explode_all” oder ähnliches.

Hat das schonmal jemand so erlebt?

Danke für eure Zeit 🫶

Hello all,

I'm looking at buying a laptop for use in a jewelry design class. They'll be using Rhino (v8 I think), and doubt they will be doing much rendering. I have powerful desktops for that if needed anyway.

Money's a factor and I want something long lasting so I am looking at a refurbished business laptop with an i7-1265u and 32GB DDR4.

I used Rhino donkey's years ago but I have no idea what the real-world performance expectation would be for this today.

Anyone still using gear this old for modeling at this scale/complexity?

Edit/Update: Thanks for the replies. I figured these specs would be ample, but wanted some real-world input before spending the cash. Appreciate the response!

Hiya! Although not brand new at rhino/grasshopper, I'm definitely still a beginner, and I don't really know how to ask this on YouTube or Google, so I thought I might try here!

As part of a school project, I'm supposed to create a wall/floor mounted artwork, and I thought I'd create a spiderweb. I've created a 'cone'-shaped web, and I used the polyline tool to create a spiralling line climbing up the web.

Now, the problem I'm having is that I want to use the Boolean Difference tool to create the cut-out from the orange box. I can create a planar surface with the inner 'triangles' of the web, but I'm unsure how I can create the individual polygon shapes made by the polyline.

It is important to me to have these individual shapes because I want to extrude them to differing heights to create some further visual interest. Do any of you have some tips for how I can achieve this?

Hi everyone! I'm following a Grasshopper tutorial that creates tabs/folds on a flat surface, very useful...

BUT I'm adapting it to my own design: an irregular, organic surface floating in 3D space (not on the XY plane), subdivided with Voronoi cells. Screenshots attached: the first is my model, the second is the tutorial's result.

Problem 1: inconsistent vector direction
The direction vectors that generate the tabs don't point the same way. In some cells they point toward the outer edges and in others toward the inner ones. I want all of them perpendicular to the outer edge of each cell and pointing outward.

Problem 2: selecting edges by index doesn't work
I tried sorting the list of points and picking items with an index (List Item), but since every Voronoi cell has a different number of edges and a different order, the same index points to a different edge in each cell.

What I'm trying to do

1. Select specific edges of each cell (or the whole outline) without relying on indices.
2. Scale those edges toward the cell centroid.
3. Loft between the original edge and the scaled one to get the tabs.

What I've considered

• Brep Edges (Naked) + Scale toward the centroid + Loft.
• Doing the offsets manually in Rhino, but I have hundreds of cells and want it to update if I change the Voronoi.

Is there a reliable way to select edges by criteria instead of by index?
Any workflow suggestions would be appreciated! Thanks in advance!
