stile  300 x 40 x 20 mm  oak
       - mitre 45 deg on right_end, back_edge inside

Code¶

From woodwright/examples/joints.py, which imports the names it uses (see From an example to your own design):

def mitre_corner(
    stile_length: float = 300, rail_length: float = 200, width: float = 40, stock: Stock = OAK
) -> Assembly:
    """A picture frame corner: both ends mitred across the face, lengths to the outside."""
    asm = Assembly("mitre_corner", root_location=STANDING)
    stile = asm.add(Board("stile", stock, length=stile_length, width=width))
    rail = asm.add(Board("rail", stock, length=rail_length, width=width))
    asm.join(MitreCorner(stile.right_end, rail.left_end, stile.back_edge, rail.back_edge))
    return asm
