I made a small update for NGon 3.0.0 version for developing further wood-wood connections (Joint tab).
It is an update for the previous 2.4.5 joinery-solver version, that contains a better functionality, rewriting and structuring larger part of code. Most of the components employ Rhino 6 NGon mesh face grouping to build adjacency graphs and finding the right connection topology.
The images below come from the new components from Joint subcategory including some basic sample files. I am planning to make proper tutorials to make the introduction to joinery in beams and plates and post it in this thread. The code is developed as part of IBOIS, EPFL studies Laboratory for Timber Constructions ‐ EPFL
There are four different ways how joints could be displayed and cut from the element volume.
Polyline methods remains the fastest one, mesh boolean is the most robust when volumetric cutting is needed and BRep boolean is also optimized to perform cuts in a separate thread:
The overall idea in the Joinery Solver comes from Tiling method where a Unit connection is oriented to connection zone. There are more peculiarities how to this method was made more effective. I would like to thank @DanielPiker who showed the principle of ChangeBasis Rhino transformation that applies to larger than this timber joinery set. Interestingly, this idea extrapolates to timber plates not only beam elements in quite fast and efficient way.
