In which a unique label or identifier can be tied to every face as such and have it persist through non-destructive transformations (rotation, translation or scaling).:
1 - Bottom; 2 - Top; 3->6 - Sides
A specific face could later be referenced and used through its identifiers in grasshopper or in a script.
In this case, face 3 will always be the “front” of the object, so a grasshopper script can move the box to the World Origin and align the “front” to the X axis, facing towards -Y. The steps of the operation could then be applied to other objects as well, maintaining their relative positions to the box.
I’m looking for the same thing. My use case: I need to boolean several objects into one, and then do a remesh operation, with the resolution of the faces determined by the objects original ‘parent’ solids.
I think the most simpel but a bit brute force approach is to create a very rough mesh per face and use the inner vertices as sample points against the parents.
Note that also geometry can hold custom data / user strings but it is not clear / documented when this data survives or gets lost for example if you attach it to a surface that is part of a brep. @dale can you please clarify this / enlight us: will user data attached to a surface/ face of a breb survive boolean operations and / or transportations ?
Thanks
