Millwork Shop Drawings and Basic Drafting Standards

Now I generally like to Blog about things that will help Educate our Clients so here is a little About Drafting and Drafting Standards. 

Drawing is considered to be a universal language. 

Drafting is a technical drawing used by designers to graphically present ideas and represent objects necessary for a designed environment. A set of these drafted illustrations is called a construction document (CD). There are common rules and standards to ensure that all designers are able to understand what is in the drawing. These design drawings use a graphic language to communicate each and every piece of information necessary to convey an idea and ultimately create a design.

Architectural drafting.

Architectural drafting is basically pictorial images of buildings, interiors, details, or other items that need to be built. These are different from other types of drawings as they are drawn to scale, include accurate measurements and detailed information, and other information necessary to build a structure. These documents are graphic representations to communicate how to do the construction,
remodeling, or installation of a design project. These include drawings for floor plans, elevations, sections, details, ceiling plans, finish schedules, and mechanical information such as electrical, plumbing, air conditioning, and heating plans.

Types of Drafting

There are three categories of drawings in interior design: process drawings (preliminary images, sketches, schematics, etc.),construction documents (drafted drawings, working drawings, plans, elevations, sections, details, etc.), and presentation drawings (illustrated sketches and three-dimensional views including perspectives, obliques, isometrics, etc.).
A Major Phase are the drafted drawing of which there are also three different types: technical sketch, mechanical drafting, and CAD (computer-aided drafting). These all fall under the heading of architectural drafting as they each convey building detail in scale and use of a common
graphic language.

Technical Sketch

Like an artist may use sketches to develop ideas for a painting or sculpture, technical sketches are used during the development of ideas for initial or preliminary plans. The ability to make quick and accurate sketches is a valuable advantage that helps you convey design ideas to others. A sketch may be of an object, an idea of something you are thinking about, or a combination of both.

Mechanical Drafting

Mechanical drafting is a refined style of drawing in which the pencil or pen is guided by devices such as t-squares, parallel rules, straightedges, compasses, triangles, and French curves. These drawings are developed only after the conceptual phase of a project has been completed and the design is finalized. However, it is typical to see revisions of construction documents as well as Millwork Shop Drawings Redlined in this Mechanical drafting style. However Since the advent of CAD the large majority of Drafting is performed on a Computer screen!

Computer Drafting

CAD is Our primary Drafting type for doing Millwork Shop Drawings.
When drafted documents are prepared on a computer, they are referred to as computer-aided drafting (CAD). An advantage of CAD is the speed of revisions to a document. Instead of redrafting an entire page alterations can be made quickly and easily and the page reprinted or plotted. CAD drawings can also be easily stored electronically and shipped to other designers who can make revisions or alterations. A large amount of design and drafting work can be completed quickly on CAD, however, you will still find need to use technical or mechanical drafting for design development and Redlines.

Drafting Sheet Size

According to ANSI (American National Standards Institute) in the United States an 8.5 x 11 inch piece of paper is an architectural “A” size sheet. This is typically referred to as letter size. The “B” size sheets are 11 x 17 and are typically referred to as a "tabloid" size sheet of paper. The “C” size sheets are 18 x 24 inches and the “D” size sheets are 24 x 36 inches. In the Millwork Shop Drawing Industry we find that Architect work on big paper "Arch D" so most Architects like to get big paper back as a Shop Drawing Submittal. Another thing that leads us to us Arch size "D" in the Millwork Shop Drawing Industry is the AWI Standards in which we govern ourselves by.   AWI calls for a Minimum Scale of 1" for plans and elevations and 1-1/2" scale for sections and full to half scale Details.

CAD (Computer Aided Design)

Today, the mechanics of the drafting task have largely been automated and accelerated through the use of Computer Aided Design systems (CAD).

There are two types of Computer Aided Design systems (CAD) used for the production of technical drawings, two dimensions ("2D") and three dimensions ("3D").

2D CAD systems such as AutoCAD replace the paper drawing discipline. The lines, circles, arcs and curves are created within the software. It is down to the technical drawing skill of the user to produce the drawing. There is still much scope for error in the drawing when producing first and third angle orthographic projections, auxiliary projections and cross sections. A 2D CAD system is merely an electronic drawing board. Its greatest strength over direct to paper technical drawing is in the making of revisions. Where as in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch. The 2D CAD system allows a copy of the original to be modified saving considerable time. 2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide no way to check the various components will fit together.

3D CAD systems such as Pro/ENGINEER first produce the geometry of the part, the technical drawing comes from user defined views of the part. Any orthographic, projected and section views are created by the software. There is no scope for error in the production of these views. The main scope for error comes in setting the parameter of first or third angle projection, and displaying the relevant symbol on the technical drawing. 3D CAD allows individual parts to be assembled together to represent the final product. Buildings, Aircraft, ships and cars are modeled, assembled and checked in 3D before technical drawings are released for manufacture.

Both 2D and 3D CAD systems can be used to produce technical drawings for any discipline. The various disciplines; electical, electronic, pneumatic, fluidic, etc., have industry recognised symbols to represent common components.

BS and ISO produce standards to show recommended practices but it is up to individuals to produce the drawings. There is no definitive standard for layout or style. The only standard across engineering workshop drawings is in the creation of orthographic projections and cross section views.

Drafting can represent two dimensions ("2D") and three dimensions ("3D") although the representation itself is always created in 2D (cf. Architectural model). Drafting is the integral communication of technical or engineering drawings and is the industrial arts sub-discipline that underlies all involved technical endeavors.

In representing complex, three-dimensional objects in two-dimensional drawings, the objects can be described by at least one view plus material thickness note, 2, 3 or as many views and sections that are required to show all features of object.

Sketching

A sketch is a quickly executed freehand drawing that is not intended as a finished work. In general, a sketch is a quick way to record an idea for later use. Architect's sketches primarily serve as a way to try out different ideas and establish a composition before undertaking a more finished work, especially when the finished work is expensive and time consuming.

Architectural sketches, for example, are a kind of diagrams. These sketches, like metaphors, are used by architects as a mean of communication in aiding design collaboration. This tool helps architects to abstract attributes of hypothetical provisional design solutions and summarize their complex patterns, hereby enhancing the design process.
