General Usage Instructions

The Add-In can be found in the DESIGN Workspace, SOLID tab, and 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".
