Good engineering practice of updating standards
A sectional view must be identified by its title consisting of the full word SECTION followed by the pair of letters; for example, , etc. The purpose of this section is to outline general Auto CAD practices that have been implemented to promote drafting efficiency, and access and portability of the design drawings. If it becomes necessary to rotate a sectional view, the degree of rotation and direction are specified. The designer will furnish reference materials and others requested by the checker. All official APS drawings are produced on the Auto CAD system. 3.2.9 All dimensioning symbols will be of standard shapes and sizes. Character height will be .13 or multiples of dependent on drawing scale. Refer to latest ANSI Standards in Dimensioning and Tolerancing Book, Appendix C, Figure C-1. The layers shall be identified by names, rather than by numbers as in the existing drawings. An electronic file of the symbols will be provided by the D&D Supervisor. 3.2.11 Colors and line types shall be assigned by layers in all new drawings. 3.2.8 All text shall be in ROMANS vertical font, (not slanted). When two or more materials must be identified individually in a drawing, use the material-specific symbology of the latest ANSI Standards wherever applicable. 3.2.6 The drawing coordinates x,y = 0,0 shall be on lower left corner of the screen. The only exception will be when the parts must show break lines.
Avoid use of letters I, O, Q, S, X, Y and Z for sectional views. 1.3.3 Detail views shall be shown in the same plane and in the same arrangement as in the principal view. 3.2 3.2.1 All drawings produced on the Auto CAD system shall comply with the applicable ANSI standards and the standards not included in this manual.
1.2.7 Prints are not to leave the Laboratory with pencilled or penned markings. 1.2.11 The use of multiple sheet drawings should be avoided if possible.
This includes, but is not limited to: (a) Specific materials called for by name, identifying number, and specification. (g) Finish specifications such as painting, plating, etc. 1.2.6 Dimensions given are to be the ones used to fabricate, inspect, and match other parts.
Catalog number, short description, supplier name, and quantities are to be given on the parts list.
1.2.2 Commercially available components are to be used whenever possible.
