Fusion 360 CAD & CAM Batch Exporter (CAMExporter)

CAMExporter is a high-performance C++ add-in for Autodesk Fusion 360 that batch-exports CAD + CAM manufacturing data into a clean, reproducible, shop-ready folder structure. It captures CAM setups, operations, tools, parameters, WCS/stock, generates setup sheets, and optionally exports STEP geometry, F3D archives, and HSMWorks-compatible tool libraries.

If you need a reliable way to archive machining jobs, transfer CAM intent, or reproduce Fusion 360 toolpaths in HSMWorks, CAMExporter provides a practical “one-click” export pipeline for both single documents and entire Data Panel folders.

Why CAMExporter for Fusion 360 CAD/CAM?

Manufacturing teams often need more than a post-processed NC file:

• Job reproducibility: preserve setup definitions, operation trees, tool assignments, and parameter values.
• Process traceability: keep WCS, stock definitions, and the operation list that created the program.
• Collaboration: share a self-contained export package with colleagues, vendors, or a programming office.
• Batch archiving: export all projects in a Fusion Data Panel folder (including subfolders) in one run.

CAMExporter is designed for Fusion 360 CAM users, CNC programmers, manufacturing engineers, and CAD/CAM pipeline builders who want structured exports suitable for job packets, PDM/PLM attachment, or manufacturing archives.

Key Features (Fusion 360 Add-In)

• Export CAM setups and operations with deep parameter capture
• Extract tool definitions (JSON + optional .tools library)
• Generate setup sheets (HTML) with screenshots
• Export CAD geometry (optional STEP AP214)
• Create native backups (optional F3D archive)
• Write WCS + stock JSON for downstream validation
• Create a feeds & speeds CSV for quick shop-floor review
• Batch export entire Data Panel folders (recursive)
• Skip existing exports for fast incremental runs
• Per-document debug logs for auditability and troubleshooting

Commands in Fusion 360

CAMExporter installs two buttons into the Utilities tab in both the Design and Manufacturing workspaces.

Export Options (Toggle Per Run)

Both commands show a checkbox dialog before exporting. Each export type can be enabled independently.

WCS/Stock data and Feeds & Speeds CSV are always produced alongside CAM Export (they share the same toggle).

What Gets Exported (CAM, Tools, Parameters, Job Docs)

CAMExporter focuses on manufacturing completeness: capturing both human-readable documentation (setup sheets, markdown summaries, CSV) and machine-reconstructable structures (template XML, parameter lists, tool JSON).

CAM Export (JSON)

The main payload is cam_export.json, which includes:

• Setups and operation trees
• Operation strategy identifiers
• Status flags (suppressed, warnings, failures)
• Tools (full geometry + cutting parameters)
• Enumerated parameters (typed values, expressions, editability)
• Embedded Fusion/HSM template XML for reconstruction

Setup Sheets (HTML)

Setup sheets are exported to setup-sheets/:

• One HTML page per setup
• Includes rendered screenshots
• Useful for printing or attaching to job travelers

Geometry Exports (Optional)

To support downstream CAD/CAM or archiving:

• STEP AP214 export: geometry/<docname>.step
• Fusion archive (F3D): geometry/<docname>.f3d

Tool Library Export (Optional)

For portability across HSM-based CAM environments:

• Generates <docname>.tools — an HSMWorks-compatible XML tool library

WCS + Stock Export (JSON)

Exports work offsets and stock definitions per setup:

• wcs_stock.json with setup-level WCS axes/origin and stock dimensions

Feeds & Speeds CSV

Creates a fast review sheet for programming verification and shop communication:

• feeds_speeds.csv (Excel-friendly)
• Columns include setup, operation, tool number, RPM, feed, DOC, stepover

Three-Layer Extraction Strategy (Maximum CAM Fidelity)

Fusion CAM data can be difficult to reproduce from a single API path. CAMExporter uses a three-layer extraction strategy to capture maximum detail reliably.

This approach provides both:

• A “source of truth” snapshot (template XML)
• Searchable, typed parameter data (enumeration)
• Portable tool reconstruction (tool JSON / .tools)

Output Folder Structure (Per Document)

Each Fusion document exports to a self-contained folder:

<output-dir>/<document-name>/
├── cam_export.json          # CAM setups, ops, tools, parameters, template XML
├── wcs_stock.json           # Work coordinate systems + stock definitions per setup
├── feeds_speeds.csv         # Quick-reference table: operation, tool, RPM, feed, DOC, stepover
├── <document-name>.tools    # HSMWorks-compatible XML tool library
├── export.log               # Per-export debug log
├── geometry/
│   ├── <document-name>.step # STEP AP214 export
│   └── <document-name>.f3d  # Fusion native archive
├── setup-sheets/
│   └── Setup1.html          # HTML setup sheet (one per setup)
└── setups/
    └── <SetupName>/
        └── Readme.md        # Markdown summary with operations table, tools, stock info

Setup-Level Markdown Readme (Job Packet Friendly)

Each setup receives a Readme.md inside setups/<SetupName>/ containing:

• Setup name and type
• Stock: mode, material metadata (name, category, hardness), dimensions and offsets
• Operations table: ordered list, strategy, tool number, RPM, feed rate, surface speed, status indicators (⚠️/❌), suppression state, pattern/folder grouping
• Tools table: unique tools referenced by the setup (number, type, diameter, description)

Example:

Drill & Tap

Type: setup

Stock

Mode: From Solid

Dimensions: 60 × 58 × 2

Offsets: sides=0.1, top=0.1, bottom=0

CAM JSON Schema Overview

cam_export.json is structured for both readability and downstream automation.

cam_export.json
├── exportVersion, exportDate, documentName
├── fusionVersion, hostname, username
├── setups[]
│   ├── name, strategy, status flags
│   ├── templateXML        ← full XML of the setup (paste into HSMWorks)
│   ├── parameters[]       ← setup-level params
│   └── operations[]
│       ├── name, strategy, operationId, status flags
│       ├── toolJson         ← complete tool definition (geometry, flutes, etc.)
│       ├── toolParameters[] ← tool params enumerated
│       └── parameters[]     ← operation params (feeds, speeds, depths, etc.)

WCS / Stock JSON

wcs_stock.json
├── exportDate, documentName
└── setups[]
    ├── name
    ├── wcs: { origin: [x,y,z], xAxis, yAxis, zAxis, modelFlip }
    └── stock: { type, width, height, depth }

Batch Mode: Export Folder (Data Panel Recursive)

The Export Folder command is built for CAD/CAM batch export and manufacturing archiving at scale.

Process overview:

1. Displays export option checkboxes
2. Opens a folder picker (default: Desktop/fusion-export)
3. Scans the current Data Panel folder recursively for .f3d files
4. Opens each document, runs selected exports, then closes it
5. Documents with no CAM data are silently skipped
6. If Skip Existing is enabled, already-exported documents are skipped
7. Shows a summary dialog on completion

This makes it practical to generate repeatable export packages for:

• customer job folders
• yearly manufacturing archives
• supplier handoff bundles
• internal CAM review and quoting

HSMWorks Workflow (Reproduce Setups + Import Tools)

CAMExporter output is designed to help rebuild or verify jobs in HSMWorks-style environments.

Reproducing Setups

Each setup includes templateXML, containing Fusion/HSM native data. It can be loaded in HSMWorks via:

• Setup::createFromTemplateXML()
• or saved as a .hsmworks-template (pipeline-dependent)

Importing Tools

Tool portability options:

• Import <docname>.tools directly as an HSMWorks tool library XML
• Reconstruct individual tools from toolJson via Tool::fromJson()

Feeds & Speeds Review

Open feeds_speeds.csv in Excel for a quick overview of:

• operation list
• RPM and feed rates
• depth of cut and stepover

Useful for shop-floor reference and CAM setup verification.

Debugging & Traceability

Every export writes a per-document log:

<output-dir>/<document-name>/export.log

The log includes:

• API call tracing and results
• Errors (missing CAM data, null pointers, file I/O issues)
• Skip decisions (no CAM data, output already exists)
• Timing and completion summaries

If an export appears to fail silently, export.log is the first place to check.

Installation & Deployment

Deployment Layout

The post-build step copies the manifest and icon resources automatically:

%APPDATA%\Autodesk\Autodesk Fusion 360\API\AddIns\Exporter\
├── Exporter.dll
├── Exporter.manifest
└── resources/
    ├── export-cam/      (16x16.png, 32x32.png)
    └── export-folder/   (16x16.png, 32x32.png)

First-Time Setup in Fusion 360

1. In Fusion 360: UTILITIES → Add-Ins → find Exporter → Run
2. The CAM Exporter panel appears in Utilities for Design and Manufacturing
3. Use Export CAM (current doc) or Export Folder (batch export)

Tip: enable Run on Startup so the commands are always available.
