The scope of small scales of representation, that is, drawings that are reductions of reality, are usually good for big dimensions. Architect scales use standard proportional ratios with 0.25 in. Note that the scale notation of 1/4-inch, for example, means 1/4-inch on the drawings equals 1 foot of the actual building, or 1-48 ratio scale. 1.1.2 Scale, Unit, and Tolerances All CAD drawing models should be drafted at full scale in architectural units, such that one drawing unit equals one inch. It’s a place for you to share your vision of how we could develop standards better and how they could add greater value to Australian society by being delivered in more user focused ways. Architect drawings show different building components and elevations. • Selection of the proper scale shall determine readability of all objects contained in the drawings. •The drawing number should receive the greatest emphasis and have a height greater than 1/4". It's too hard to figure out 3/8 and 3/32 scale drawings with a tape. Calculating Scale Factor. Such similarities allow us to provide high quality scenery elements for architectural models. • Drawings shall be created at full size and plotted at the appropriate size for the project. It states drawings shall be drawn to a scale that depicts all details of the item clearly and accurately, except diagrams, pictorials, cable assemblies and tabulations and other drawings not prepared to any scale … There is generally a hierarchy of scales for architectural drawings. Tolerances for construction drawings are implicit within professional service contracts. However, since these drawings get placed on sheets of paper that are much smaller, a scale factor is required so that the final drawing has a usable conversion factor. Many architecture offices have their own standards with regard to the order of sheets in a construction document set and most architects are quite opinionated about whether the Structural drawings belong before or after the Architectural drawings. Drawings are done to a scale. The selection of the appropriate scale is governed by the level of detail needed to be shown, and the size of the display medium. Generally, interior elevations are drawn to the same scale as the floor plan(s).
