Test 1 on Engineering Drawings
Graphical representations of ideas - correct answer Engineering drawings
_________________ are the primary method used to control production - correct answer Drawings
Rules for specifying dimensions - correct answer 1) Decimal point and zero are omitted for whole numbers (ie
30 not 30.0)
2)metric - if a dimension is less than 1mm, a decimal point and zero is added (ie 0.4)
English - dimension is less than 1 in, the
preceding zero before the decimal is omitted (.1
in)
On drawings, a note usually indicated if dimensions are in __________ or ____________ - correct answer mm
or in
American system of projection - correct answer third-angle projection
places the front view under the top view

front, top, bottom, right, left, rear
, All views of a drawing are assumed to be rotated by _____ degrees unless otherwise noted - correct answer 90
The view that shows the most __________ is shown as the front view - correct answer detail
Auxiliary view are used to show the true _____ and _____ of features not parallel to any principal views -
correct answer shape and size
Sectional views are drawn to show ________ _________ - correct answer interior details
