Basic workflow: 

1. Prepare Your Model

• Create or open a design in Autodesk® Fusion®
• Model a solid body that will contain the lattice structure
• Save your design before generating complex lattices 

2. Launch the Add-In

• Go to Utilities tab → Add-Ins panel
• Click Lattice Generator
• The dialog will open with default settings 

3. Select Your Body

• Click the Body selection box
• Select a solid body or mesh body from your design
• **Important:** Only solid bodies support shape conformity (lattice confined to exact shape)
• Mesh bodies will generate lattice within the bounding box only 

4. Choose Lattice Type

• Select from Lattice Type dropdown (Gyroid, Schwarz Primitive, BCC, Octet Truss, etc.)
• For TPMS lattices, choose TPMS Type (Sheet or Solid) 

5. Configure Basic Parameters

• Cell Size: Size of individual lattice cells (smaller = finer detail, longer processing)
• Wall Thickness (TPMS): Thickness of the lattice walls
• Strut Diameter: (Strut-based): Diameter of connecting struts
• Resolution: Mesh detail level (0.5mm recommended; smaller = smoother but slower) 

6. Generate

• Click the Generate button
• Wait for processing to complete (may take several minutes for large/complex lattices)
• Inspect the preview mesh in your viewport
• The OK button will enable once preview is generated

7. Finalize or Adjust

• If satisfied with preview, click OK to create the final mesh body
• If not satisfied, adjust parameters and click Generate again
• Click Cancel to discard and exit

Install:

1. Download the installer from the Autodesk App Store.
2. Right-click on the "Downloads" folder and select "Open in Finder".
3. Right-click on the "LatticeGenerator_macos.pkg" -> "Open With" -> "Installer".

Uninstall:

You can unload the add-in without uninstalling it by clicking the "Stop" button when the add-in is selected in the list box on the "Add-Ins" tab of the "Scripts and Add-Ins" dialog.

Unchecking "Run on Startup" causes the add-in not to be loaded in future sessions of Fusion.

- Navigate to the ./ApplicationsPlugins folder and select the app bundle you want to uninstall

- Either drag the app bundle to the Trash or right-click and select “Move to Trash”

- Right-click on the Trash-Can and select “Empty Trash”

- If you prefer keystrokes, you can also just select the app bundle and then hit Command+Delete to move the app to Trash, then empty the Trash and the app will be removed.
