JoinSurfacesn’t (or Don’t Join Surfaces) is a plugin that displays a selected part’s touching parts just like the “Join Surfaces” option without creating any welds.
Don’t understand the problem that this plugin solves?

To-do:
The current implementation does one raycast per face, that is not ideal for a lot of scenarios.
Support Models and multiple Parts.
