Enlarged and detailed view may be used, if necessary. b) The outline drawing shall consist of three parts: 1) A drawing with dimensional symbols (capital letter) as shown in Figure 1 with applicable footnotes, if necessar
23、y. 2) A tabular listing relating to the drawing symbol to the actual dimensions. Where possible, this shall be shown on the same page as the drawing. 3) An “actual-size“ sketch (scale 1:1). c) The outline drawing shall be executed in the third-angle projection. d) The function and identification of
24、the lead connections (termination) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. e) Descriptive footnotes may be used at the bottom of/ or adjacent to, the drawing with proper reference to the body of the drawing. f) All dimensions
