The purpose of dimensioning is to define size and location of the various materials and components. Extension lines should be started 1/16" from the object , and extend beyond the dimension … Extension lines indicate the points between which the dimension figures apply. Notes should always be concisely phrased to make a point that could be difficult and cumbersome to display in a drawing. OJ QJ UVhmH nH "j��= 9. Note the strong contrast between the visible lines of object and ANSI Y14.5M-1994 is the current standard. Architectural Symbols and Conventions Architectural Drafting Line Work Arrowheads are drawn freehand. ' The dimensional system cannot be left hanging in limbo; it must be tied to tangible usable items apparent in the construction. Notes can be placed inside dimension lines; that is to say, between the dimensions and the object drawn. 8. The first dimension lines should be spaced 3/8" or 10 mm from the object, and 1/4" or 6 mm away from each adjacent dimension . The following list of architectural dimensioning standards is taken from “Architectural Working Drawings”, by Ralph W. Liebing and Mini Ford Paul (Wiley - Interscience, 1983). It is a good idea to group notes around the construction to which they refer. Extension lines should be started 1/16" from the object , and extend beyond the dimension line by 1/8". The spacing between the notes must be greater than the spacing between individual lines. The ability to dimension properly requires the following: 1. To increase legibility, identical units, spaces, or solids should be dimensioned at one element of the series, and by a note in a specific area should be shown as repetitive. A note may contradict the dimension given; for example, a 2x4 stud may show a measurement of one and one-half inches (1 ��) by three and one-half inches (3 ��). &. ��ࡱ� > �� ! A column, for instance, would have a centerline running in both directions. Notes can sometimes be placed close together. � �
] 6 ? % It is important that each space be identified with name or number for specific purposes such as scheduling or reference. Notes should be as close to the point of application as possible; for example, the topmost note directed to the floor slab should describe the topmost material in the floor slab construction, and so on down the line. Technique of dimensioning: the standard for appearance of lines, the spacing of dimensions, the size of arrowheads, and so on allow others to interpret your drawing. 11. 0��� A����ŅP���X�nAA

They may also show specific locations or references. 3. Dimensions, Notes and Titles. All drawings should agree - most of all with the specifications.
