Hi all, I am trying to get a grip on working with Elefront and I have a ‘basics’ question I think: Is it possible to reference and add attributes to Grasshopper geometry, or does the geometry first need to be (baked as) Rhino geometry? Thanks! Wilco

Do you have access to Rhino 8? If so, you don’t really need EleFront. No matter if you use the new Grasshopper Rhino components or another approach, attributes are baked with the geometry so I don’t think there is a way to add attributes to an object which exists only in Grasshopper.

Hi Martin, thanks. I still have Rhino 7 at the moment. I have made a sample to see if it could work in my GHdefinition, but like you say it only works when I use referenced Rhino geometry, see sample files (if you have time :)) That would be a pity since the geometry in the larger definition exist…

I can’t look at these files. Is this using dendro? Or what else is the component with the green icon?

It’s from Wombat (Unroll Brep). I would have to look for some other unrolling tool to replace it with, is there any you use?

I’m using a script but it’s using the Rhino 8 script editor. The original version is somewhere in the forum. [image] Unroll Surface component GH1 Grasshopper [Unroll] Unroll.gh (14.3 KB) Text dots are omitted, I don’t think GH supports them native (unless I missed that)…

Maybe so, if I understand correctly. sample elefront_20250411 a.gh (14.1 KB) [image]

Yeah something like that, but the circle only applied to the point ‘type B’. I tried using Elefront’s Filter by Layer but I’m clearly missing something :sweat_smile: Thanks sample elefront_20250411 b.gh (15.7 KB) [afbeelding]

Ah but then the circle is applied to all 3 points. It should only go to point ‘type B’.. Those unrolled points are not baked Rhino geometry. I guess that’s why I can’t Filter by Layer because they’re not in a layer.

I believe that after Unroll the points lose the connection with the Layer attribute. The selection must be made before Unoll. Try this. sample elefront_20250411 c.gh (16.1 KB)
