Hi Insekt,

James created a couple versions of HexGridMacro.

There is TriGrid macro, and HexTesselation Macro, and HexFlatGridMacro, for nodeeditor.
Also Conformal Mapping to the Torus.
Try MoI searches "+hex +grid +node", and also "+hex+lattice" (without a space).

Also ABH Packing 160221X.zip macro for a circular packing of circles, that is not quite hexagonal.

Often, an "old" nodeprogram will have individual nodes which are "red", i.e. obsolete, or not present in the latest nodeeditor version, which need to be replaced with a more recent version... (This can be frustrating...)
I have barely used the nodeeditor for a long time. It is helpful to save Macro's and NodePrograms in AppData nodeeditor directory, in Macro and NodeProgram folders...
All 3 of the following terms are "programs":
A node is an individual component of a nodeprogram.
A macro is a collection of nodes. A macro appears as a single component, but down one level, contains multiple nodes.
A nodeprogram is a collection of nodes and/or macros, with input and output, which builds MoI geometry...

MoI Array commands can also be used...

So are you looking for a Lattice, or a Packing?
