Overview

Intralattice is a collection of generative CAD components for Grasshopper, used to generate solid lattice structures within a 3D design space. It was developed as an extensible, open-source alternative to current commercial solutions. This is an early Beta version.

Core Components

The generative process is divided into the following modules.

1. CELL - Defines a unit cell topology.

• PresetCell - Library of built-in unit cells
• CustomCell - Input for user-defined unit cell (includes validation)

2. FRAME - Generates a lattice frame by mapping the unit cell topology to a design space.

• BasicBox - Simple box lattice
• BasicCylinder - Simple cylinder lattice
• ConformSS - Conforming Surface-to-Surface lattice
• ConformSA - Conforming Surface-to-Axis lattice
• ConformSP - Conforming Surface-to-Point lattice
• UniformDS - Trimmed Uniform Lattice (within Brep or Mesh)

3. MESH - Generates solid mesh of the lattice frame.

• Homogen - Homogeneous (constant strut radius)
• HeterogenGradient - Heterogeneous (gradient-based strut radius)
• HeterogenCustom - Heterogeneous (custom strut radius)

4. UTILS - Extra components for pre/post-processing.

• AdjustUV - Adjust UV-map of a surface
• CleanNetwork - Removes duplicate curves from a list of curves
• MeshReport - Validate a mesh (printability)
• MeshPreview - Preview a mesh

Core Data

Many of the relevant algorithms, and data structures, are encapsulated in the following classes.

• UnitCell - For constructing/validating unit cell.
• Lattice - For lattice wireframe mapping.
• ExoMesh - For solid mesh generation.
• EndoMesh - Coming soon
