Copyright  Goodheart-Willcox  Co.,  Inc.  Chapter  17  Materials  in  AutoCAD  443  Document  Materials  Area  Materials  are  added  to  the  Document  Materials  area  from  the  Library  area.  Hovering  over  a  material  swatch  in  the  Library  area  displays  two  options.  See  Figure  17-3.  Picking  Adds  material  to  document  adds  the  material  to  the  Document  Materials  area.  Picking  Adds  material  to  document  and  displays  in  editor  adds  the  material  to  the  Document  Materials  area  and  opens  it  in  the  materials  editor  (discussed  later).  After  you  add  a  material  to  the  document,  a  swatch  for  the  material  appears  in  the  Document  Materials  area.  Picking  the  button  on  the  right  end  of  the  Document  Materials  title  bar  opens  a  drop-down  menu.  The  options  in  this  menu  allow  you  to  control  which  materials  are  displayed  in  the  Document  Materials  area.  You  can  show  all  materials,  only  the  mate-  rials  that  are  applied  to  objects  in  the  drawing,  selected  materials,  or  unused  mate-  rials.  Materials  may  be  sorted  by  name,  type,  color,  or  category.  They  can  be  displayed  in  thumbnail,  list,  or  text  view,  and  the  size  of  thumbnails  can  be  changed.  Refer  to  Figure  17-2.  Picking  the  show/hide  button  on  the  Document  Materials  title  bar  hides  the  display  of  the  Library  area.  Pick  the  button  again  to  expand  the  Library  area.  Right-clicking  on  a  material  in  the  Document  Materials  area  displays  a  shortcut  menu.  There  are  several  options  available  in  the  shortcut  menu:  •  Assign  to  Selection.  This  is  active  if  one  or  more  objects  are  selected  in  the  scene.  The  material  will  be  applied  to  the  selected  object(s).  •  Select  Objects  Applied  To.  All  objects  in  the  drawing  that  have  the  material  applied  to  them  are  selected  in  the  drawing  window.  •  Edit.  This  displays  the  materials  editor  for  editing  the  selected  material.  The  materials  editor  is  discussed  later  in  this  chapter.  •  Duplicate.  A  copy  of  the  material  is  added  to  the  drawing.  A  new  material  is  added  with  the  same  name  as  the  original  material,  but  with  a  sequential  number  added  to  the  name.  •  Rename.  This  option  is  used  to  change  the  name  of  the  material.  It  is  a  good  idea  to  rename  all  of  your  materials  to  meaningful  names.  •  Delete.  This  option  removes  the  material  from  the  drawing.  If  it  is  currently  being  used  in  the  drawing,  a  warning  alerts  you  to  this.  Continuing  with  the  deletion  removes  the  material  from  the  objects  in  the  drawing  as  well  as  from  the  Document  Materials  area.  It  is  not,  however,  removed  from  the  library.  •  Add  to.  This  option  displays  a  cascading  menu  with  two  choices.  The  material  may  be  added  to  the  Favorites  library  in  the  Library  area.  This  is  excellent  for  organizing  materials  that  you  frequently  use  and  want  to  make  available  for  quick  access  in  other  drawings.  You  can  also  add  the  material  to  the  active  tool  palette.  •  Purge  All  Unused.  This  option  removes  from  the  drawing  all  materials  not  currently  assigned  to  an  object.
