The  2D  Wireframe  visual  style  is  the  default  display  when  a  drawing  is  started  based  on  the  acad.dwt  template.  Wireframe  displays  are  the  quickest  to  display.  When  a  drawing  is  started  based  on  the  acad3D.dwt  or  acadiso3D.dwt  template,  the  default  display  is  the  Realistic  visual  style,  which  is  a  shaded  display.
