About the Lattice Feature
Lattice is an internal framework designed to optimize part properties. For example, use lattice to maximize the strength-to-weight ratio.
Lattice Definition
You define lattice using two elements:
• A single cell—Defines the dimensions, the shape, and the internal structure of a single cell.
• The duplication of the cell—Defines the way the single cell is propagated in the volume.
You add lattice to a Creo part, as a feature of the part. Although the internal volume must have boundaries on all sides, you can use a datum plane as one of the boundaries. You can select adjacent solid surfaces that are not in the volume to close the open boundaries of a volume. You can also set the lattice to ignore small holes.
Types of Lattice
There are two types of lattice:
• 3D—Adds 3D cells in a pattern of your selection. You can select the cell shape and control its structure by defining the number of beams of the cell. You can control the width and shape of the beam, choose whether to add balls on the beam intersections, etc. You can control how the lattice cells are propagated in the internal volume.
• 2.5D—Adds 2.5D cells in a pattern of your selection. You can select which cell shape you use, but not its structure. You can control how the lattice cells are propagated in the internal volume. You can add slot-shaped drain openings to the structure.
