Fusion 360 Script to automate the CAM process for 2D plates.

• Batch import of STEP/IGS files into the current Fusion design
• Load part dimensions and settings from a JSON configuration file
• Nest parts using Fusion’s 2D true-shape Arrange solver
• Generate CAM setups with stock offsets and WCS from customizable templates
• Delete empty or invalid toolpaths to streamline operations
• Post-process drills and profiles into NC programs via user‑selected folder

• Autodesk Fusion 360 with API support
• The .cps post‑processor file for Laguna (path configured in NewNCProgram.py)
• JSON config files matching the expected schema (see test.json)

1. Clone or download this repository to your local machine.
2. In Fusion 360, open Scripts and Add-Ins → Scripts tab, click ➕ (Add), and select the FullstackScript folder.
3. (Optional) Check Run on Startup and click Run to execute immediately.

• JSON config (.json): Must include keys such as
  • width, length, height, trueheight
  • machine (e.g., "IQ", "Swift"), material (e.g., "Aluminum", "Polycarb")
• HSM templates: Update file paths in
  • lib/SetupGenerator.py for .f3dhsm-template files
  • lib/NewNCProgram.py for the .cps post‑processor

Run the script from the Scripts and Add-Ins dialog. It will:

1. importStep: Prompt to select and import STEP/IGS files
2. importJSON: Prompt to select a JSON config and load data
3. AutoArrange: Arrange imported parts on a 2D plane
4. SetupGenerator: Create CAM setups and apply HSM templates
5. DeleteToolpaths: Remove empty or invalid toolpaths
6. NewNCProgram: Post-process and save NC programs to a chosen folder
