Objective:

How to transition a structural ribbing workflow from the old to new latticing blocks

​
Applies to:

  • Conformal Lattice from CAD Face
  • Cell Map on CAD Face

​
Procedure:

1. Import your CAD part using the Import Part block and then create variables of the CAD’s faces to be used in multiple places. (How to work with CAD bodies) 2. Creating a conformal lattice in the old and new lattice pipelines.

  • We use the Periodic Lattice block and Columns as Graph Unit Cell to create columns that can be used to Boolean subtract from the lattice to generate holes.

Notes:

  • The new pipeline allows other unit cells such as TPMS unit cells and custom implicit unit cells. This was not possible with the old lattice pipeline.
  • There is now a difference in the unit cells mapping to the CAD face.
    • Old: Only the unit cell cube corners were mapped, and nodes within a cell were interpolated within the mapped cube.
    • New: All unit cell nodes are now being mapped to the CAD face (and offset accord to face normal).
And that’s it! You’ve successfully applied a conformal lattice to your CAD part. Are you still having issues? Contact the support team, and we’ll be happy to help!
