Purpose  The  goal  of  this  text  is  to  guide  you  through  a  logical  sequence  of  learning  activities  and  to  use  this  knowledge  in  a  skill-building  format.  •  It  is  important  for  you  to  have  a  solid  foundation  in  the  understanding  of  dimensioning  and  tolerancing  terms,  definitions,  and  concepts  before  beginning  a  study  of  geometric  dimensioning  and  tolerancing.  •  The  geometric  dimensioning  and  tolerancing  concepts  are  introduced  to  you  in  a  methodical  manner  to  help  ensure  that  you  have  full  understanding  of  every  basic  concept  as  you  build  knowledge  toward  more  advanced  applications.  •  The  concepts  are  covered  in  an  easy-to-learn  sequence.  •  The  text  progresses  using  a  format  that  allows  you  to  become  comfortable  with  the  concepts  as  you  build  understanding  from  one  chapter  to  the  next.  •  The  basics  of  interpreting  and  applying  geometric  dimensioning  and  tolerancing  practices  should  be  mastered  before  advanced  topics,  such  as  designing  and  inspecting  for  GD&T,  are  covered.  •  GD&T  is  approached  in  this  text  as  an  easy-to-understand  subject  rather  than  something  complex  and  difficult.  To  the  Student  Geometric  Dimensioning  and  Tolerancing  is  for  Manufacturing  Technology  students,  Drafting  Technology  students,  and  professional  upgrade  training.  Everything  you  need  is  in  this  text.  For  Manufacturing  Technology  students:  •  Chapter  tests  reinforce  the  previously  learned  topics.  The  chapter  tests  can  be  used  as  open-  or  closed-book  tests,  or  they  can  be  used  for  content  review.  Test  answers  can  be  written  on  the  textbook  pages.  •  Print  reading  exercises  are  provided  following  every  chapter.  This  gives  you  the  opportunity  to  read  prints  illustrating  the  geometric  dimensioning  and  tolerancing  concepts  related  to  the  chapter.  Answers  to  the  print  reading  exercises  can  be  written  on  the  textbook  pages.  •  The  prints  are  actual  industry  drawings  that  were  created  using  computer-  aided  design  and  drafting  (CADD).  •  Computer-aided  manufacturing  (CAM)  concepts  are  introduced.  •  A  comprehensive  final  exam  is  provided  to  solidify  the  learning  that  has  been  conducted  throughout  the  course  of  study.  Final  exam  answers  can  be  written  on  the  textbook  pages  unless  otherwise  specified  by  your  instructor.  For  Drafting  Technology  students:  •  Chapter  tests  reinforce  the  previously  learned  topics.  Test  answers  can  be  written  on  the  textbook  pages.  •  The  print  reading  exercises  are  optional,  but  can  be  considered  helpful  in  understanding  more  about  the  information  provided  in  prints.  Answers  to  the  print  reading  exercises  can  be  written  on  the  textbook  pages.  4
