Applying Your Knowledge
1. Contact several industrial drafting
departments. If possible, obtain copies of
the standards they use for dimensioning.
Compare how similar or dissimilar they
are. Do they vary by industry?
2. Obtain copies of several industrial
prints. Study how they are dimensioned
and how notes are used. Are there any
provisions for foreign components to be
used with the items on the prints? Will
the parts be exported?
