Extrude Srf in GH - missing options

[seltzdesign (Armin Seltz)]

I have the same issue as in this thread: Extrude surface distortion but in GH.

I am extruding a surface created from some text:

As you can see on the inside of the D there is an error similar to the thread above.

If I bake the surface and extrude in Rhino with normal options I get the same error. If I switch on “Split at Tangents” it works fine.

Is there a reason why that option didn’t make it to Grasshopper? I can’t see any good reason why it wouldn’t.

Is there a plugin/script where I can use those options?

Recently, there was a topic about similar problem, which was not a problem with geometry, but rather about the render mesh setting. You could make your geometry with increased resolution or use a custom mesh setting.

How to correct geometry display problem?

Greetings to all, I have a question regarding what appears to be a display discrepancy, but maybe not? So I am dealing with some planar shapes, which I then thicken: [image] notice that here meshing is disabled: [image] with meshing enabled, the geometries look like this: [image] so… meshing disabled shows the quality I want: [image] meshing enabled doesn’t: [image] After baking (regardless of meshing disabled or enabled), I get this, where regions marked with an ‘x’ are what …

Hi Kim.

Thanks so much for your answer. Well, I am not sure what exactly causes it, but it also happens in Rhino in the same way. I noticed that rebuilding the curves helps with it, but I still don’t get why the option was omitted for GH, when in Rhino you don’t have to uselessly rebuild any curves and can just use the Tangent option.

Run “ExtractRenderMesh” command in rhino and check the result if you like…

Okay, I tried some things again, and yes, you are (of course) right as always

ps: I had already marked your answer as solution, but took it away again, as it’s technically not a solution, but a workaround. Having similar options in GH as in Rhino is the solution. Oh and of course improving the meshing algorithm, which is pretty flaky…

@seltzdesign

it’s technically not a solution, but a workaround.

I’m struggling with this right now. I need those splits at tangents !
And it’s not a meshing issue in my case, but simply that I need to access individual faces, and no a bizzar’o surface made of flat and round parts.
