I am working in rhino for stone carving and recently I am facing an issue for this like the sweep hight getting extreme large then expected as well I am facing one major doubt in my mind that how can I do these stuffs in rhino as this things getting more complex afterwards when I will start work on large so do I need to switch to matrix or should I need to continue on rhino as shapes are getting weared when applying 3D shapes
So should I switch to Matrix for this or the rhino is enough???
There are a lot of directions this question can go inā¦ and Iām not sure what your main goal is here.
On one hand you mention that your results from the 2 rail sweep command are too high. And that starts make sense if your goal was to have a low relief carving. So if this is a matter of constraining Rhino to flatten out itās 2 rail sweep results,ā¦ and constrain things to a lower relief carving. Then you can do that by adding in another curve profile near the middle that helps define how tall the projection is going to be away from the background plane. Maybe you need more than one extra curve profile to get the results you wantā¦ You way need to rework you starting profile to get more of an undercut effect rather than a straight projection off of the back plane.
Your comment about āgetting extreme large then expectedā results in this area of Rhinoā¦ meaning NURBS modeling toolsā¦ doesnāt make sense given that other folks might use this same approach to model their Cars, Airplanes, and Boats, or topography. By comparison your model is already pretty modest in size. Which is why I started my comment off with the question about what sort of relief you want to achieve in your carving. Is it Low, Mid, High?
As far as Modeling this in NURBS, or Matrix Poly Meshā¦ Iām not sure what you should do. Some of this is about personal preference (using the tools you like to use), and some of this might be about what process follows this Rhino Modeling effort. Are you making these Rhino Models as studies for working out your own future carving efforts? Or is there a secondary part of all of this that ends heading to the CNC machining world.
So when I readā¦ āSo should I switch to Matrix for this or the rhino is enough???ā I say that depends on things I donāt know about yet. On some level you have to decide what workflow you like, AND what you want to learn to do in Rhino. I wouldnāt want to see anyone give up on NURBS modeling tools, in favor of something else if itās at the expense of taking a shortcut around learning the tools in the first place. I might argue that there is great value in trying to limit a small range of commands to a certain model up to a point. And of course there even more value in know how to model the same thing using a variety of tools/workflows. So be careful about what you try to avoid doingā¦ if your on the early part of the learning curve in Rhino. It might be worth it to you later on, regarding the tools you choose to use and get comfortable with now.
You have two leaves to model the foreground, and the background one. after that Iād be looking to run a āPolarArrayā around your mid point and then cleaning up whatever messy geometry you end up with as a result.
I have shared the image in the program file as base image in that I am stucked as I need the shape as the curved to be used in CNC miling and design
My main work is to create a stone design in this with proper shapes where flat part need to be have flate and curved part need to be as carved and hight for the sweep and leaf need to be maintained so after completing the design I am creating the tool path for CNC machin in powermill then I am applying that carving on stone so my main goal is that and I need to do 3d stone carving design in this so I am stucked in that three option
Only rhino is enough for this ?
should I go with Matrix (still confuse)
Any other option with rhino (Like grass hopper but not even 1% sure for this)
so what should I do for that I am sharing some refrence Images which I am currently working for learning and designing for the clint
So please suggest me the proper way to learn this type of things and even possible learning resource even if they are paid that is also ok but I want to design the stone carving for the CNC miling so please refer shared images with this so can have better idea for guidence
As well @Tom_P you shared that where I am stucked so main thing in the same image I have shared is I am facing issue is that in the refrence image from which I am working is that it has less curved par on it and hight as per the need so if I am adding that same sweep shape with rhino it is giving shocking hight even after adding multiple shapes as well so need to maintain shape as look like flower also it is type of INDIAN ANCIENT TEMPLE CARVING type to also that taste also have to be maintain so that is the thing from my side
Probably the easiest way to tame the height on your model is to scale it along the Z-Axis (or try Scale 1D). Something around 0.8 looks a bit better than Rhinos default sweep resultsā¦ but that doesnāt address other concerns you might have about a more organic leaf shape or curvature.

I agree with Tomās ideas above. And I probably lean pretty heavily towards making frequent posts on this forum ā which youāve already started to do ā as the best way to learn Rhino. Tutorials offer one persons approachā¦ where this forum brings in a wide cross section of approaches and ideasā¦ and somehow therein lies a nice assortment of best practices, and efficient modeling tips that you can make use of. and Ideally you can do both of theseā¦ work through a tutorial and then post on this forum about the places where your own model starts to get off track.
A broken (even unfinished) model with a clear indication of what you would like to end up with is probably going to get more comments from a wider group of users than the ones that require a fair amount of guess work and speculation about what the end goal is suppose to look like.

On a side note: If you have access to these carvingā¦ I think it would be interesting to make a mold of themā¦ cast itā¦ and then cut sections strategically along certain directions of the forms. That cross section is going to inform the contour shapes youāll need to use to make close copies in Rhino. After a few of these sections cutsā¦ I think things will start to align as too what the surface contours are really doing in the finished piece, and hopefully establish guidelines or targets for the contours inside of Rhino.
Maybe avoid the mold/casting/efforts, and measure down from the top for a reverse style depth map. Depth measurements taken with a vernier caliper from a known height. (a Gimbal Arm) could create quick set of relative reference points for areas of interest.

fwiw, I have almost always found that topics on this forum which are concerned with Fillets, and Blending across awkward areas of geometry (Network Surface Commands) to be quite useful forum reading. And this is especially true for those that find elegant solutions ā or manually rebuild messy contours into smooth streamlined transitions. The bonus being two-foldā¦ 1) You end up learning a few good tips, about new commands or alternative uses of already known commandsā¦ 2) These topics often expose new ways of Thinking about the problem, and how to Organize your workflow with a better way of chaining together commands that are needed to address the issues in play.
