The construction drawings for the trellis where pretty simple. I just needed to give the dimensions of the different pieces, and the rules (the construction details) for connecting them. The dimensions locating the trellis are given from an existing point, the upper left hand corner of the kitchen window.

All of the wood is 4×4 redwood.

Drawings:
Top: Plan (on top), front elevation (below) and side elevation (to the right). Each shows the same thing (the trellis in this case) from a different viewpoint.

Iso: A three dimensional drawing that shows how the pieces go together. This kind of drawing is especially helpful when pieces are at different angles.

Footing Detail of Center Piece: A short piece is used between the base (which can only take connections to elements pointing straight up) and the angled verticals.
