New issue treating an extrusion as a surface since build March 12, 2024

Grasshopper GH for Mac

Hi,

After upgrading to the latest version, a GH model that has been working well has stopped working. The culprit seems to be that before this version, an extrusion was being treated to a surface when fed to a SDivide component. See attached example.

Is there any workaround for this, or is it possible to download an earlier version of the software while the issue is looked into?

They did that wrong and fixed it in R8.5.
Here is a way.

Is this a bug? DeBrep an Extrusion makes 1 untrimmed surface - Grasshopper - McNeel Forum

Hi Matteo -

That file requires a non-standard plug-in:

Hi Wim,

In my program, that component is just a standard “surface” component used to organise the layout. Not sure why it does that on yours. You can replace it with a generic “Geometry” panel or remove it entirely.

Thanks,

This worked. Saved my week really :slight_smile:

Hi Teo -

You need to extract surfaces from the extrusion object for the downstream components to work:

Hi Wim,

Thanks for your suggestion.

This used to work before V8.5. I need the grid to consider the surface as a whole, not 4 surfaces, because the results will be fed to srfgrid and then panelling tools. The solution above suggested by Quan Li works properly.

That’s fine.
