Novice needing advice on best workflow

Hi Rhino experts,

I’m trying to make this 2d shape into a 3d mesh.
I initially used NetworkSrf to build most of it… but now I’m stumped on how to create/fill the last missing parts.

I have a full 2D shape that I trimmed the ‘ends’ of this crescent shape. Then used NetworkSrf to get the majority of what I need. I just don’t know what tool/step would be ideal to get this crescent ends to connect/build to the surface.
So I can then create a mesh to use in Zbrush/3Dcoat.

Any advice?




added flat suface bottom

Just need to ‘hole fill’ this last remaining part

Ok, just converted what I had into a mesh, then hole filled. Imported into 3DCoat as voxels.
Currently smoothing out all the wavy surface

more views of what I’m trying to achieve. Just like this… but now trying to get a smoother mesh surface.



In the future, what would be the best way to achieve what I’m trying to do here.
‘Inflate’ a 2D shape, similar to an extrude… but with a slope and taper.
Also, without all the wavy surface features…

Many thanks

Hello dreko,

Sorry, but I am not sure what you want the result to be from your post. Perhaps posting the file if you can would help. An inclination is to suggest:

surface> offset surface ; solid=yes

but that seems to easy to be true. From there, given a closed polysurface you then can use the mesh tools.

If you are using R8 ShrinkWrap may help to achieve [along X workflow] the final goal of having a closed 3D mesh.

Thank you,

Andy

Hello dreko,

I think the last set of images are in the view port’s Render mode. If so, please change to Ray Trace mode- and see what you get.
You can also select the object [before you convert it to a mesh- or maybe you can get what you want working with the mesh object? ] >properties > Render Mesh Settings> check the box-Custom Mesh > Adjust. In Rhino 8 a very nice feature [ I think this is new?] is there are some presets you can use-- and F1 will take you to the related help page.

Thank you,

Andy

Hi Andy,

No those last set of images are screenshots from inside of 3DCoat, where I voxelized the mesh I had Rhino make.

I then started smoothing out the lumps and wavy mesh from Rhino.

Ultimately, I’m going to work the mesh, so I can then 3D print it out.
I just wish I could have gotten a smoother model surface from Rhino. I’m not sure how to best make the 3D mesh/model I’m trying to get.

I think from my screenshots, you can see I need to puff up, or inflate that 2D shape. However, I need that extrusions to be tapered at the sides, have a rounded top surface, and the entire top surface then slopes from higher height to lower height.

How could one go about , trying to make a surface the way I describe? Which tool is best? NetworkSRF is what I used… to get close

Here’s the raytraced screenshot

Hi dreko, im a novice as well but i think it would be easier to actually use sub-division tools to create this instead, because that way you can actually control the points instead of leaving it all to the system to “guess” what you’re trying to achieve.

Interesting. I haven’t used any of the SubD tools inside Rhino8.
What workflow would use suggest? I don’t see a NetworkSRF command under the SubD menu.

Open to trying! Just not sure how to make it

im using rhino 7 currently, majority of the tools should be the same in rhino 8 as well but what i usually do is build a surface > convert into subd > Convert to subd ( Tool is called ToSubd ) and from there i adjust the points to the right areas, or if you have a mesh which in your case you do, you can convert it into subd straight away,

It might not convert into the desired shape so you should keep a copy of the original before converting to subd. From there you just have to move the points the right areas.

I suggest turning these filters on so you can selelct the points, surfaces, vertexs and curves/edges.
