The complexity of the design dete rmines the number and types of drawings. W orking drawings may be on more than one sh eet and may contain written instructions call ed specifications.Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely desc ribe the parts, both visually and dimensionall y;(b)show the parts in assembly;(3)identify a ll the parts; and (4)specify standard parts. Th e graphics and text information must be suffi ciently complete and accurate to manufactur e and assemble the product without error.Ge nerally, a complete set of Working drawings for an assembly includes:(1) Detail drawings of each nonstandard parts.(2) An assembly or subassembly drawing showing all the standard and nonstandard p arts in a single drawing.(3) A bill of materials (BOM).(4) A title block.A detail drawing is a dimensioned, mult iview drawing of a single part, describing th e part' s shape, size, material, and surface roughnes s, in sufficient detail for the part to be manuf actured based on the drawing alone. Detail d rawings are produced from design sketches o r extracted from 3-D computer models. They adhere strictly to ANSI standards and the sta ndard for the specific company, for dimensio ning, assigning part numbers, notes, toleranc es, etc.In an assembly, standard parts such as t hreaded fasteners and bearings are not drawn as details, butare shown in the assembly vie w. Standard parts are not drawn as details be cause they are normallypurchased, not manu factured, for assembly.For large assemblies or assembled with large parts, details are drawn on multiple she ets, and a separate sheet is used for the asse mbly view. If the assembly is simple or the p arts are small, detail drawings for each part o f an assembly can be placed on a single sheetMultiple details on a sheet are usually d rawn at the same scale. If different scales are used, they are clearly marked under each det ail. Also, when more than one detail is place d on a sheet, the spacing between details is c arefully planned, including leaving sufficient room for dimensions and notes.31. Based on the message, which of the follow is wrong ?A) standard parts needn' t drawn as detailsB) for simple parts, sometimes need'n t to draw the detail working drawingC) for large assemblies details may dra wn on multiple sheetsD) If different scales used in a single sh eet, they should clearly marked under each d etail32.
