Download Understanding Working Drawings: Assembly, Detail, and Fabrication Drawings and more Slides Computer-Aided Design for Engineers in PDF only on Docsity! Working Drawings-1 Docsity.com Skill-Development Goals • Construct “Working Drawings” from the Two Primary Components – ASSEMBLY Drawing – Parts List (a.k.a. Bill of Material, or BoM) • Use AutoCAD to Insert and Scale Up/Down a Standard Title Block to Fit the Assembly Drawing • Place BoMs on the AutoCAD Title Block Docsity.com Fabrication Drawing TWO Parts on this Sheet →Poor form Docsity.com Fabric 3 ation Drawing 4.06 1-000 ASTRATON 07/31/98 f (3/8 00 TUBE) / 4-40 UNC-28 THRU (ONE WALL” ONLY fear 7 REL PER w2652 hs /o2/od er] Dm 4,06 WAS:3.27 ADDED c’BORA, MTL_IS_.OB3W_WAS:.03: 18/02/94 ET NOTE: THIS PART MAY BE PROCURED FROM AN OUTSIDE VENDOR 2.
