Box Joint

This is an Autodesk Fusion 360 Add-In for creating CNC friendly box/finger joints.

Editable Feature

The Box Joint appears as a single Feature in the Timeline.

• The Box Joint Feature can be edited after creation just like any other built-in feature.
• The joint will be automatically recomputed if any of the dependent bodies earlier in the Timeline are changed.

CNC Friendly

The joint has been designed to be cuttable on a CNC machine.

• Can be cut flat from a single side on an 3-axis CNC machine.
• No voids are visible even though inside corners are rounded.

• Using GitHubToFusion360. Paste the github link https://github.com/EvilHacker/BoxJoint into the GitHubToFusion360 Add-In.
• Downloading the Add-In zip file from github and extracting it to:
  • ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/AddIns (Mac OS)
  • %appdata%\Autodesk\Autodesk Fusion 360\API\AddIns (Windows)

Usage

The Add-In can be found in the DESIGN Workspace, SOLID tab, MODIFY panel.

Start by creating a model with simple butt joints. Bodies to be joined should contact each other at a planar surface. Multiple bodies can be butted up against each other at any angle to form a box-like structure.

To create a Box Joint, open the Box Joint Add-In and select the outside faces of the bodies to join. A Box Joint will be created between every pair of bodies that butt up against each other.

A Box Joint feature can be modified at any time by selecting it in the timeline and choosing "Edit Feature".
