woodwright¶

A semantic CAD library for woodworking. You describe furniture the way a woodworker thinks about it: boards and rods with named sides, and the joints between them. woodwright works out the joinery, the cut sizes and where every part goes, and produces 3D models (STEP, STL), drawings (SVG, PDF), the plans in one PDF and cut lists.

A chair with mortise-and-tenon joints, assembled and exploded (projects.chair). Every tenon and mortise is derived from the joints between the parts.

import woodwright as ww

oak = ww.Stock.board(thickness=20, species="oak")

frame = ww.Assembly("corner", root_location=ww.orient(right_end=ww.UP, back_edge=ww.RIGHT))
stile = frame.add(ww.Board("stile", oak, length=600, width=60))
rail = frame.add(ww.Board("rail", oak, length=300, width=60))  # shoulder to shoulder
frame.join(ww.MortiseTenon(tenon=rail.left_end, mortise=stile.back_edge))

print(frame.resolve().cut_list())

stile  600 x 60 x 20 mm  oak
       - mortise 50 x 8 mm, 42 deep, in back_edge
rail   340 x 60 x 20 mm  oak
       - tenon 50 x 8 mm, 40 long, on left_end

You give the design dimensions and the joint: the tenon, the mortise, the rail's cut length and its placement are derived.

Where to start¶

woodwright is built on build123d. This is an early alpha: the API will still change.
