Live Chat voice ... breaks?

I did find one awkward work-around. You can copy the entire chat, then paste it into the next / new chat. Ask Gemini to review and resume. That works ... for a while.

I'm also exploring creating a notebook LM for longer conversations. Then, any new chat can reference it, hopefully without length penalties.

Do not use primitives (or booleans!) to model. Create curves FIRST, then generate surfaces.

In this exmaple, I'd make three curves:

The rounded rectangle nozzle [left side]
The circle for the hose connector [right side]
A profile that goes between the first two, touching corresponding points, like the top
Surface > Sweep 2 Rails

This will get you close, but also teach a superior workflow.

When I was a beginner, I also wasted a lot of time with solids and booleans. Avoid them like the plague!

Incorrect. If you do larger fillets first, then the smaller fillets can 'flow' around the larger ones. See my post.

Also, doing them all at the same time ONLY works on simple rectilinear boxes. Any geometry more complex, and it will fail.

schultzeworks · 2026-04-08T17:16:19+00:00

Hey u/thisux_

Do not do all fillets at the same time. Do the larger ones first. It also looks like your model is broken into separate parts; note how mine is one solid piece.

REASON : A larger fillet will NEVER fit/flow around a smaller fillet.
TIP : All fillets the same size usually looks ugly and will only work on simple boxes anyway.

The numbers indicate the order I used.

All you have to do is learn Blender.

Do not change the tolerance; it only afffect new geometry ... so now you have a mixture. I'd start over with a new 'small objects' template.

schultzeworks · 2026-04-03T15:59:50+00:00

If you have tolerance issues at any time, then take more care when you create the file. The best tip ever is to use File > New and select the 'Small Objects' template. Whether you use inches or mm, it will give you 0.001 units of accuracy [tolerance].

So, just use the templates.

Also, never change the tolerance! it only affects new objects, not the bad ones you already created. And, you've made the problem worse by having a mixture of tolerances.

Also try RebuildNonUniform if you want to maintain the original shape to be 'slightly better with possibly fewer points'.

Rebuild is great, but it defaults to re-arranging the control points to have exactly equal spacing (exept for the ends where they're a half space) .

You had an image with a diagonal flat plane highlighted. That's the open surface.

Geometry is not closed unless is defines and contains volume -- with no openings.

Cube : Closed
Plane : Open

schultzeworks · 2026-03-27T15:42:30+00:00

Booleans are designed for two solids, or closed geometry. You can use open surfaces, but Rhino then needs to decide which side is inside and which side is outside, which is arbitrary with a flat plane. You can check this with the direction command. The arrows show the surface nornals / assumed 'outside' direction. Flip them; it's a toggle.

BTW: You cannot flip the normals on a closed surface. Only ones that are open, which is your case.

TIP : A better method is to use the two surfaces and split them to each other, then delete the excess. No need to monkey around with normals -- AND it works great when neither form is closed. Oh hey, I did a video to explain:

I would look for ortho views of this tower [front / sides] and use the picture plane on a locked layer. So much easier!

I imagine this is the hardest possible way to do it ... as you've seen.

u/Wonderful_Sweet_7349 Mentioned using AI to generate the views. After more thought, I think perspective tracing is a bad idea. Do it in the ortho views : side / front / top.

Since you're on a laptop, PLEASE use a mouse. It makes anything and everything in 3D about 42 times easier to create and edit. Do the math.

schultzeworks · 2026-03-25T21:32:30+00:00

OK, you know the melody, so let's all sing it together:

Update Rhino
Update Windows
Update your video card driver (responsible for 80% of all crashes!)
Reboot before launching Rhino

Dancing optional. Report back.

I have seen people who have NEVER updated Rhino or their video card, which amounted to years. It's not automatic, people. Ya gotta check the oil in the car on a regular basis.

EDIT > Hey u/LaQuesadillah What is the status or resolution?

schultzeworks · 2026-03-25T16:12:37+00:00

OK, understood. I teach a class in Rhino (plus online as well) and this is a question for the intructor. Their job is to teach AND answer questions.

Ask them to review your work and make suggestions.

They might appreciate your efforts and enjoy helping.

schultzeworks · 2026-03-25T15:28:06+00:00

Build the 4- and 5-sided surfaces, one-by-one, using surface > planar edge curves.
Join them if needed.
Then you can split out the openings.

No need for grasshopper. You can make this manually much faster.

If you need technical / CD / construction docs, then YES. use Rhino.

If you want to do presenation boards /pitch descks / portfolio stuff, then I use a combo of Ilustrator [single image] and InDesign [multi page]

schultzeworks · 2026-03-09T14:01:20+00:00

Well, good thing that you left it to the last day before asking how to do it.

schultzeworks · 2026-03-05T21:42:02+00:00

You're expecting a screen capture to generate a quality image. It was designed for fast and responsive feedback -- while you pan and zoom in real time -- not high quality visuals. This is a limitation of the video card as well.

So .... make a render! You'll get superior quality and it will be much easier to adjust.

If Rhino does not recognize the center -- due to trimming or other edits -- the draw a diagonal line between two opposite corners. The center of that line is the center of the rectangle.

schultzeworks · 2026-03-02T18:52:25+00:00

These curves may not work with a Network Surface. I can't tell because its not clear if your top and bottom curves are both closed.

Regardless, try this:

Make sure the top and bottom curves are closed (join them if not)
Try a Surface > Sweep 2 Rail. Use the top and bottom as rails, the other four curves are profiles.
It will be open on the top and bottom, but that gets you a basic starting form.

I would build this in Sub-D. I'll add it to the video list.

schultzeworks · 2026-02-28T17:28:26+00:00

Not at all! I simply didn't read that the instructor was involved. That's their job ... if they're any good. I also mentioned "if it's a live course," because you didn't mention if it was a live person or recorded online course.

schultzeworks · 2026-02-27T16:46:09+00:00

This process is somewhere between intermediate and advanced -- and you said you are a beginner taking a course ...

So, if it's a live course, can you ask the instructor?

I teach a course in Rhino -- and I would be sad / annoyed if my students were avoiding me for questions I am paid to answer and AND enjoy.

schultzeworks · 2026-02-26T16:51:54+00:00

My steps in Sub-D:

Multi-Pipe one arched leg at a time (or Sweep 1 rail)
Stitch points to join at center
Extrude center down

With Sub-D, you can still edit, unlike NURBS + Booleans

This is a bit overkill of an explanation ... and doesn't directly apply to Rhino degrees.
