Introduction  to  AutoCAD  Learning  Objectives  After  completing  this  chapter,  you  will  be  able  to:  ✓  Defi  ne  computer-aided  design  and  drafting.  ✓  Describe  typical  AutoCAD  applications.  ✓  Explain  the  value  of  planning  your  work  and  system  management.  ✓  Describe  the  purpose  and  importance  of  drawing  standards.  ✓  Demonstrate  how  to  start  and  exit  AutoCAD.  ✓  Recognize  the  AutoCAD  interface  and  access  AutoCAD  commands.  ✓  Use  help  resources.  Computer-aided  design  and  drafting  (CADD)  is  the  process  of  using  a  computer  with  CADD  software  to  design  and  produce  drawings  and  models  according  to  specifi  c  industry  and  company  standards.  The  terms  computer-aided  design  (CAD)  and  computer-aided  drafting  (CAD)  refer  to  specifi  c  aspects  of  the  CADD  process.  This  chapter  introduces  the  AutoCAD  CADD  system.  You  will  begin  working  with  AutoCAD  and  learn  to  control  the  AutoCAD  environment.  AutoCAD  Applications  AutoCAD  Applic  a  tion  s  AutoCAD  commands  and  options  allow  you  to  draw  objects  of  any  size  and  shape.  Use  AutoCAD  to  prepare  two-dimensional  (2D)  drawings,  three-dimensional  (3D)  models,  and  animations.  AutoCAD  is  a  universal  CADD  software  program  that  applies  to  any  drafting,  design,  or  engineering  discipline.  For  example,  use  AutoCAD  to  design  and  document  mechanical  parts  and  assemblies,  architectural  buildings,  civil  and  structural  engineering  projects,  and  electronics.  2D  Drawings  2D  drawings  display  object  length  and  width,  width  and  height,  or  height  and  length  in  a  fl  at  (2D)  form.  2D  drawings  are  the  established  design  and  drafting  format  and  are  common  in  all  engineering  and  architectural  industries  and  related  disciplines.  computer-aided  design  and  drafting  (CADD):  The  process  of  using  a  computer  with  CADD  software  to  design  and  produce  drawings  and  models.  command:  An  instruction  issued  to  the  computer  to  complete  a  specific  task.  For  example,  use  the  LINE  command  to  draw  line  objects.  option:  A  choice  associated  with  a  command  or  an  alternative  function  of  a  command.  CHAPTER  1  1
