Fusion 360 Add Dimensions to Description

A Fusion 360 add-in that automatically adds bounding box dimensions (Length, Width, Height) to component descriptions.

Overview

This add-in creates a command in Fusion 360 that calculates the bounding box dimensions of selected components and adds them to the component description in a standardized format (L: XXmm, W: XXmm, H: XXmm). Dimensions are sorted so that Length > Width > Height, following conventional notation.

Features

• Adds or updates component dimensions in the description field
• Automatically sorts dimensions (Length > Width > Height)
• Works with single or multiple component selections
• Updates existing dimension information if already present
• Converts dimensions to millimeters

Installation

1. Download the repository as a ZIP file or clone it
2. In Fusion 360, go to the Scripts and Add-Ins dialog (under Tools tab)
3. Select the Add-Ins tab and click the green "+" icon
4. Navigate to and select the folder containing this add-in
5. Click Run to start the add-in

Typical add-in directory in Windows

• C:\Users<user>\AppData\Roaming\Autodesk\Autodesk Fusion 360\API\AddIns\DimensionDescription

Usage

1. Select one or more components in your design
2. Click the Add Dimensions to Description command in the Inspect panel
3. The dimensions will be added to each component's description

How It Works

The add-in:

1. Gets the bounding box for each selected component
2. Calculates the length, width, and height dimensions
3. Sorts the dimensions to follow the convention where Length > Width > Height
4. Updates the component description with the formatted dimension string
5. If dimensions already exist in the description, they are updated rather than duplicated

Requirements

• Fusion 360 (2018 or newer)

Known Issues

• Length and width values might need to be corrected in some cases depending on your model orientation
