Create a Custom Strut Unit Cell

Define a custom set of edges and points in a normalized cube to use as a strut lattice unit cell.

Strut lattice unit cells are defined by of specifying edges and points inside a normalized cube that are repeated inside the volume being filled with a lattice. This workflow demonstrates how to edit or create custom unit cells for the Strut Lattice tool.

Custom strut lattice unit cells can be used to fill any implicit volume and can be used with all the same field-driven parameters and properties of built-in unit cells.

  1. On the Implicit Modeling ribbon, select the Strut Lattice tool.

    Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
  2. Unit cells can be edited or created using the following workflows. Both options will open the unit cell editor.
    • Edit an existing unit cell:
      In the guide panel, select the unit cell to edit from the Cell Type dropdown and click Edit.

    • Create a new unit cell:
      In the guide panel, select Create Unit Cell from the Cell Type dropdown.

    The Strut Unit Cell dialog is displayed,
  3. Optional: To import, export, or delete unit cells, use the Import , and Export , or Delete button.
  4. Enter a Name for the cell. All unit cells of the same type require unique names. If you tupe a name that already exists, a unique number will be appended to the name.
  5. Use the Nodes table to define the coordinates inside the unit cube to be used in specifying the edges and points of the unit cell. The coordinates are normalised between 0-1.
    • Add and remove nodes from the table using the Add or Remove buttons.
    • Promote or demote nodes in the list by selecting a row and using the Up or Down buttons.
  6. Use the Connectivity Table to define the edges of the unit cell by specifying the indices of the start and end nodes for each edge. The indices are zero-indexed: to reference the first node in the Node Table, an index of 0 should be used. A node can be connected to itself to create a point instead of an edge.
    • Add and remove edges from the table using the Add or Remove buttons.
    • Promote or demote edges in the list by selecting a row and using the Up or Down buttons.
