Drawings provide a two-dimensional representation of a three-dimensional object for the purpose of construction or layout. For the everyday sheet metal worker, these drawings are a road map to constructing a job, fabricating a fitting, or installing architectural elements.
This process has evolved from hand drafting to include computer-aided drafting, and 3D modeling of the modern age.

Center Aisle Entryway: Hand-drafted mechanical system layout and drafting table
This hand-drafted and detailed system was designed for the Clorox Company in Pleasanton, California. Information on this drawing includes everything necessary to layout and install the mechanical system on the job. The drawing includes hand-texted elevations, fitting sizes, dimensions, and special installation details. This drawing is displayed on a vintage drafting table with reticulating arm.
Right Top Panel- Hand-Drafted Architectural Details
This hand-drafted architectural detail page comes from the drawing set for the former San Leandro Training Facility. All details for wall applications were drawn by hand to provide clarity of architectural installation applications.
Left Top Panel- Mechanical system layout using computer-aided design
This drawing of a mechanical system depicts a mechanical duct run coming from an air handling unit using 3D modeling software. The training program has evolved from hand-drafted layouts to incorporating software such as Revit, AutoCAD, and Navisworks. As software develops, the organization will continue to evolve learning new efficiencies and programs.
Bottom Right Panel- Antique Drafting Tools
Drafting tools such as a compass, architect scale ruler, pencil, protractor, and brush are used to create hand-drafted layouts for the sheet metal installer.
