How to create a conformal lattice from a Quad mesh

Objective:

Learn how to create a conformal lattice from a quad mesh.

Applies to:

  • Conformal lattices
  • An alternative to Lattice Body from CAD face workflows

Procedure:

1. Create a mesh, import a mesh, or extract mesh faces.

2. Add a Filter Mesh by Flood Fill block and input your mesh to filter it

3. Convert your mesh into a Quad Mesh

    • Add a Quadrangulate Mesh block
      • Input your Filter Mesh by Flood Fill block
      • Edit the Quad Mesh settings until you are happy with the result (Each quad will be a lattice unit cell)

4. Convert the Quad Mesh into a lattice

    • Add a Periodic Lattice (beta) block 
      • Add a Cell Map on Quad Mesh (beta) block
        • Add a Graph Unit Cell (beta) (You can use custom, graph, or TPMS)
          • For desired results, make sure your unit cell is symmetrical
        • Edit the Height, Layer count, and Unit cell parameter 1 until you are happy with the results

Test out the different unit cells and settings to see what you can create.

Note: Since there are many different faces within a quad mesh, the UVW of those faces may not align perfectly. This can be an issue if you are using a unit cell that isn't the same in every direction, like the gyroid unit cell. In this case, the Lattice from CAD Face workflow may be the preferred workflow.

  • For some reason, this great BETA block "Lattice Body from Quad Mesh" does not appear to be available with the latest version 2.31.2
    Is it a mistake/bug? has it been replaced by something else or a custom block?

  • Figured out how to do it with 2.31.2

  • Thanks for your comment! This was recently updated in 2.30. I've gone ahead and updated the article with the new block name.
