A lattice is an interlaced structure of nodes and beams. It is used for its high strength to weight ratio.


LTCX is Element's lattice file format (Lattice Graph Interchange Module). Our Lattice Graph interchange module allows lattices to be imported and exported in a lightweight, open source, XML based file format. This allows you to analyze even the most complex structures using your existing FEA toolset - without having to deal with slow, heavy 3D meshes.


A node is a beam connection point.

Open Beam

An open beam is a beam that doesn't connect to another beam on at least one end.


A rule is the type of cell that is patterned to construct a lattice. It is comprised of a single unit and it's tessellation

Surface Lattice

A surface lattice is a lattice that is generated on the surface of an object.


Topology is a pretty complex concept, but generally, it's the arrangement and orientation of holes in a part. When it comes to our program, 'Generate' tools execute topology operations and 'Thickening' tools execute shape operations.



Valence is the number of beams connected to a single node.
