BUG - Extrude Component - Surface Input Error

Hello,

After the “lightweight extrusions” update to the Extrude Component per WIP 8.0.23277.12305 the extrude component no longer accepts surfaces as a valid input and throws an error saying “1. Cannot extrude Surface geometry.”

Model Space (Curve & Surface):

Graph Space:

Component Error:

  1. Cannot extrude Surface geometry.

Steps to reproduce:

  1. Open New Rhino & Grasshopper File
  2. Reference or create surface in GH
  3. Connect Surface To Extrude Component

Hi @michaelvollrath,

As always, thanks for reporting!
This will be fixed next RC of Rhino.

Thanks @kike , much appreciated!

Is this fixed yet? I have the same issue on Rhino 8 SR3 2023-12-12 (Rhino 8, 8.3.23346.14001

I have not seeing this error since Kike reported it being fixed.

Perhaps something is unique with your geometry that I can’t reproduce on my end?

It’s far from unique, I extruded a triangle onto a point and then try to extrude those faces outwards. All native GH.

What I found out which is super strange is that it works fine with Normal vectors from deconstructing a plane, but does not work with mesh normal vector… even though they appear to be identical. Also constructed lines with those vectors and they move just fine.

Here the def.

I can’t locate the part of that Grasshopper definition in the .gh file that you posted… This is how that looks here, though:

-wim

This on my end.
I guess Rhino works differently on every PC :man_shrugging:

I’m on (8.4.23355.18001, 2023-12-21) and it’s likely you are not? :man_shrugging:

I specified here what version I am using. I don’t know what is up with the tone Wim.

There are multiple threads about this:

Instead of blaming the user for not updating every single day why not fix your buggy software?

I believe I fixed this bug just this week. The fix should be included in the next public service release. I think Wim was just showing that in one of the newer builds that the issue you reported had been fixed. I think he only meant to encourage you to test out the newer build when it becomes available as we’re hopeful that this issue has been resolved.
