• 270

• 310

A Line drawn with a long section, short dash, and another long section is a __________

• hidden feature

• center of a circle

• center axis of a hidden cylinder

• center of radius

Traditional drafters need to be able to create several different line widths because _______________.

• different line widths convey different information

• the line width has to do with how dark it appear in the finished drawing

• they seem to transmit better in a fax machine

• it makes no difference

Several of the tools used in traditional drafting include the following:

• divide the numerator (top number) by the denominator (bottom number)

• check the engineer's scale

• all of the above

An Engineer's scale would be used to measure lines on a drawing where the scale factor reads ________

• 1/4" = 1'-0"

• 1/8" = 1' -0"

• 1.906

• 4.7625

• 5.959
