13 ARCHITECTURAL DRAFTING

Architectural Drafting

Students in this major learn how to create working drawings and computer simulations used in the design and construction of buildings and other structures. In addition to studying design and construction basics, they practice using computer-aided drafting tools.

Drafting Equipment

		Drafting Compass and Dividers Drafting compass, dividers, drafting compass sets, beam compasses, and compass replacement parts. Complete selection below for students or professionals., all affordably priced. Great selection from quality suppliers such as Alvin. Take a look at the selection below.

Protractors for Drafting Protractors are a great drafting tool to use when draw angles other than 30°, 45°, 60°, or 90°, a protractor is used. Most protractors displays angle markings for a half-circle, or a 180° arc. There are also 360° protractors available. Here are three popular protractors. If there is one you are looking for and can't find, let us know we can get more models

Drafting Triangles 30/60 45/90 Drafting Triangles 30 60 90 Triangles, 45 45 90 Triangles, and Adjustable Triangles available in clear plastic, smoked plastic, fluorescent orange plastic, Aluminum, and steel. Below you will find 30/60 triangles, 45/90 triangles, adjustable triangles, with or without inking edges. Fairgate and Alvin triangles.

Drafting furniture including drafting chairs, office chairs, flat files, vertical files and clamps, roll files, drafting tables, light tables, light boxes and more from Alvin, Mayline, Safco, and other quality manufactures. Multiple views and projections Image of a part represented in First Angle Projection Symbols used to define whether a projection is either Third Angle (right) or First Angle (left). Isometric view of the object shown in the engineering drawing below. Main article: Graphical projection In most cases, a single view is not sufficient to show all necessary features, and several views are used. Types of views include the following: [edit] Orthographic projection The orthographic projection shows the object as it looks from the front, right, left, top, bottom, or back, and are typically positioned relative to each other according to the rules of either first-angle or third-angle projection. First angle projection is the ISO standard and is primarily used in Europe. The 3D object is projected into 2D "paper" space as if you were looking at an X-ray of the object: the top view is under the front view, the right view is at the left of the front view. Third angle projection is primarily used in the United States and Canada, where it is the default projection system according to BS 8888:2006, the left view is placed on the left and the top view on the top. Not all views are necessarily used, and determination of what surface constitutes the front, back, top and bottom varies depending on the projection used.

Isometric projection The isometric projection show the object from angles in which the scales along each axis of the object are equal. Isometric projection corresponds to rotation of the object by ± 45° about the vertical axis, followed by rotation of approximately ± 35.264° [= arcsin(tan(30°))] about the horizontal axis starting from an orthographic projection view. "Isometric" comes from the Greek for "same measure". One of the things that makes isometric drawings so attractive is the ease with which 60 degree angles can be constructed with only a compass and straightedge. Isometric projection is a type of axonometric projection. The other two types of axonometric projection are: Dimetric projection Trimetric projection Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. Oblique projection An oblique projection is a simple type of graphical projection used for producing pictorial, two-dimensional images of three-dimensional objects: it projects an image by intersecting parallel rays (projectors) from the three-dimensional source object with the drawing surface (projection plan). In both oblique projection and orthographic projection, parallel lines of the source object produce parallel lines in the projected image.
