Dimensioning
and Tolerancing |
|||
|
CAD-based techniques of dimensioning and tolerancing, including the placement of dimensions as
well as the choice of dimensioning systems using both the American National
Standards Drafting Manual--Y14 (ANSI Y14-1975 R1987) and International
Standards Organization (ISO) standards. Prerequisites: CAD150 or permission of Instructor.
