Hi @Petras_Vestartas , Firstly, thank you for the great plugin! I just have a quick question regarding this image (2/10) on the Food4Rhino site of NGon: [image] NGon Rhino Mesh NGon methods for Grasshopper [ngons2] Do these solids intersect? how are they ge…

Because projection is just additional step, planarization of sides guarantees planarity. So it depends how well you can planarize you geometry. And then you take edges lines and cut it with plane. That cut points you connect as a polyline which is flat because it sits on the plane. And how you def…

The logic is this You extrude mesh edges, planarize extrusion and project edges to average planes. I will look if I have the same geometry.

Hi Petras, thanks for the response! But as you project edges to each panel’s respective average plane, there is no guarantee that the projected panels don’t intersect one another right? A collision test on a similar(?) routine in your example file is attached. Examples_MeshLibrary180824_collision…

In the example attached you missed important part - planarization. Before projection you need to extrude mesh edges and planarize them. Planarization can be done either with ngon or kangaroo, which way is preferable to you. After planarization they will not interesect but touch each other side by…

Thanks for the response! I still don’t really quite get the workflow. I also don’t understand why projected panels based on average planes are guaranteed not to intersect one another - doesn’t it depend on the projection direction and the curvature of the base surface? If possible, seeing the ent…

ah, i finally understand it now…when you said projection i didn’t realize it was projecting onto each individual plane ALONG the vector derived from the planarized edge planes (I thought it was a simple projection along the normal of the average plane itself). Thanks again for the help and the file!…

Yes so far I seen examples either they make foundation to make the foot fit or planarized elements are cut. In coding it can be done more clean, but basically the same concept. All the mehtods in gh components are wrapped inside NGonsCore.dll incase you are used to coding.

Hi Petras, Might you be able to elaborate a bit more on the step of planarizing the extruded edges? Is this similar to the dynamic relaxation technique in K2? I couldnt seem to find any documentation online to get a deeper understanding of the component/plugin. Thanks a lot!

I was using this solver for making this: [image] HexBox - petrasvestartas HexBox Project Name: "Centre d’activités Gare Grand Chalet". Location: Rossinière, Switzerland Client: Commune de Rossinière Architect: Yves Weinand Architectes sàrl, Lausanne Timber Engineering: Bureau d’Etudes W…

thank you… big boss :slight_smile:

Hi all, I am trying to use Ngon to create an ngon solid like the one shown below: [image] I’m thinking this is the right way to start but I’m not sure what input is needed for the third parameter. thanks for any help [image]
