mesh loop

Hello all, is there a way to select a loop of faces of a mesh?

any hint will be much appreciated,

David

You mean in the way that Modo works? (or TSplines - "expand selection etc etc" - or pretty much any subdivision modeling app). If so .. no ... but using Sandbox tools you get connectivity data and then you can proceed accordingly.

Thank you Peter, i already started experimenting with it, as soon as i come up with something worth to show i will upload it in here

Well (If I understood the issue) for "growing" (obviously in steps) the selection with regard adjacent mesh faces > this is rather easy due to FaceToFace connectivity data (Face indices, that is).

For the "ribbon" part you can exploit the Mesh/Plane intersection approach.

Notify if you need some C# of mine that "inquires" a mesh and makes about 9 connectivity data trees (relate anything with anything: faces, edges, vertices in any combo).

What do you mean by 'select' in this context?

thank you David, im working with meshes i edited on the zremesher from zbrush, now i have a consitent mesh and i want to select parts of it to apply a weave or a 3d pattern on it

Well (I think) that he means: get a face and make a loop or an "expanded selection" (kinda a "ring" or a "ribbon" or a "set") due to that face). Exactly the way that Modo works (where you can control the ways that the "ring"/"ribbon"/"set" is defined: kinda like "sectioning" a mesh with a user defined plane and getting the related mesh faces, this obviously is not related with the "expanded selection" option).

TSplines has a "similar" capability (but on the other hand a TSpline is not a mesh).

Again: I think.

Yeah I figured 'select' probably means 'make a mesh containing only those faces', but I'm still not sure.

Yes exactly, sorry if i was not clear at first

Tsplines in Grasshopper lacks of many of the functons that i think allow me to do this, or maybe i havent used that much inside grashopper

TSplines (4.x and on) is like Titanic: could be the biggest thing ever but that @%%@$ iceberg spoiled the party.

This i can achieve, but im looking to do a little more
