Hi, I am trying to create a 3d model similar to the image in Rhino. I am trying with SubD, but manually making every curve is very difficult. Can I use an easier way or grasshopper to create this effect? Thank you.
Kids these days and their “is there a Grassshopper thing to make this?”
I did this almost exactly 25 years ago. NURBS. Designed to be 3d-printed mind you. On 32-bit Windows, I sat there for hours watching the virtual memory creep up to the edge of crashing the whole computer doing boolean operations.
It’s just 3D modeling, a decent amount of it. I would maybe go for NURBS over subd, I don’t think it’s really the kind of “really organic” shape subd is made for. Just get at it!

Old men these days and their tired “kids these days” rants.
I post this politely and genuinely, looking for a better approach, not for a condescending sermon with a basic extrusion and boolean model that seems complex, lacking aesthetics and control.
Yes, it is just 3D modeling, but after 25 years, it can have a smarter, more refined approach than just a decent amount of it. I will get at it.

He does have a point tho sometimes there is no easier way, there is Gordon Ramsays in the CAD world to.
With that said I’m gona go and dig a hole 
I think that if you don’t require continuity, you may have a good case for conducting a series of MultiPipe, and then place surfaces between the pipes. They need not be smooth, only intersecting. Then you can shrinkwrap the whole thing, and see how that goes.

Thank you! I will try.
Hello Eric,
I believe that David53’s approach is good one and will get you “their”. To help develop the model I would in parallel be in “render” mode. Experimenting with materials, the environment etc. and based on the image you posted perhaps a key light source. Toggling back and forth between the two e.g. Ray Trace take a look / adjust the scene <===> Shaded add some geometry. … and so forth. Perhaps more frequently than you might otherwise do.
Thank you,
Andy
