LATTICE LOFT

USER INTERFACE

Select Surfaces Button: Select two or more surfaces from the Rhino view-port
  • At least two surfaces must be selected. If just two are selected, your lattice structure will be linear. If three or more surfaces are selected, your lattice structure will be generated through the input surfaces, matching their interpolated curvature.
  • All surfaces selected must be facing the same direction and have the same UV data
  • When selecting the input surfaces, select them in chronological order
  • For best results, input surface should be untrimmed surfaces (not trimmed surfaces)
Number of Cells XYZ: Enter the amount of unit cells for each axis
  • Input the amount of unit cells you would like along each axis of your lattice
  • You can either enter an integer or use the arrows to count up or down
Unit Cell Gradients: Shift the slider left to right to control your lattice
  • Along with controlling the amount of unit cells in each axis, you can also control their size by shifting each corresponding slider
  • For now, gradients are manually controlled through a slider; point cloud and simulation result integration coming soon...
Unit Cell Family: Select from three different options
  • TPMS (Triply-Periodic Minimal Surface) Family - A group of unit cells that are made of BREP data
  • Member Family - A group of unit cells that are made of curve data
  • Custom - When selected, the user will be prompted to select geometry from the Rhino view-port. Accepted geometries: BREP (open or closed), mesh (open or closed), and curve/line. For best results, BREP data should consist of untrimmed surfaces
Unit Cell Type: Select unit cell shape from drop-down menu
TPMS Family
  • Schwarz
  • Gyroid
  • Neovius
Member Family
  • Cubic
  • Cubic-X
  • Cross
  • Octet
  • X
  • T
  • MM
  • Schwarz border

  • Neovius border
Custom Selection
Generate Button: Generates lattice with selected unit cell
  • Generate will populate the voxel structure with unit cell selected from above
  • Note: when generate is clicked, the structure created will be of zero-thickness (unless the user selects a custom cell with a volume)
  • Tip: once you have generated a structure, you can switch back to Voxels tab for adjustment
Thickness: Input offset distance and click thicken
  • Input desired offset distance in the thickness box
  • Click thicken to offset zero-thickness structure being previewed
  • Tip: structure will turn from the color aqua to the color yellow once it has been thickened
Shaded: Click check-box to preview a shaded version of lattice
  • Note: default preview is a wire-frame version to save computation time, shaded can take a long time*
  • Tip: switch between shaded and wire-frame preview for quicker iteration exploration
Done/Cancel: Closes the UI modal
  • Done - will save your structure to the Rhino view-port, if you have thickened your structure
  • Cancel - will close the UI modal
