80056. Every drafter and engineer continues to utilize both the architect and engineer's scales.
80057. Prior to the development of computer aided drafting, drafters relied on drawing boards, paper, and pencils to create technical drawings.

80064. Welding is often used for large structures that are difficult or impossible to fabricate entirely in a shop.
80065. Weldments are composed of a number of separate pieces fastened together as a unit.
80066. A seam weld is a type of arc and gas weld.
80067. The symbol for the desired weld is attached to the reference line, or shank, of the arrow.
80068. Groove weld size is usually specified on the welding symbol.
80069. In a welding drawing, joints are all shown as they would appear before welding.
80070. A fillet weld is a type of resistance weld.
80071. The usual fillet weld has equal legs.
80072. In a welding symbol, the arrow points to the joint where the weld is to be made.
80073. A groove weld is a type of arc and gas weld.
80074. Type of weld is typically not specified on the welding symbol.
80075. Welding is often more expensive when only one or a few identical parts are required.
80076. A spot weld is a type of resistance weld.
80077. Welding templates can simplify drawing welding symbols by hand.
80078. A projection weld is a type of:
80079. These weld symbols have no arrow-side or other-side significance:
80080. A back or backing weld is a type of:
80081. Welding drawings are a special type of this kind of drawing:
80082. Which of the following is one of the basic types of welded joints:
80083. In an assembly section, these parts should have their section lines left out or shown solid black:
80084. These are groups of components of a larger machine:
80085. Hidden lines are usually included on assembly drawings.
80086. In assembly drawings, views should show how the parts fit together and suggest the function of the unit.
80087. The U.S. Patent Office has strict requirements for patent drawings.
80088. Working drawings are not legal documents.
80089. Patent drawings must be mechanically correct and constitute complete illustrations of every feature of the invention claimed.
80090. Assembly drawings are usually not dimensioned.
80091. When multiple detail drawings are shown on one sheet, it is not always necessary to identify each part.
80092. In working drawings, showing two detailed parts per sheet is typically preferred.
80093. In assembly sections, bolts, nuts, and keys are typically left unsectioned.
80094. Patent applications do not always include line drawings.
80095. In 3D assemblies, the last part added to the assembly becomes the parent part.
