Starting with Creo 7, you can create lattices from a custom cell that is based in a non-BREP (boundary representation) geometry. Lattice cell part can contain solid geometry, quilts, and curves. Lattice that results is created using these elements, according to the following:

  • Solid geometry in the lattice cell part creates a solid geometry-based cell.
  • Quilts geometry in the lattice cell part creates a surface-based lattice cell. Quilts are thickened when selecting the full geometry representation.
  • Curves geometry in the lattice cell part creates a beam-based lattice cell. You can only have straight curves in the cell and those are converted into beams.
User Interface: Click Model > Engineering > Lattice. Click the Cell Type tab and then select Custom
