Introduc)ons

What  is  this  BIM  thing?

• What  exactly  is  BIM?  • Virtual  Building  •  Embedded  Intelligence  •  Simula;on  and  Analysis  • Underlying  Parametric  and  Associa;ve  Model  

How  are  BIM  and  parametric  tools  related?

A  Parametric  and  Associa;ve  Model  

While  Revit  undoubtedly  uses  parametrics  for  these  automa7c  revisions,  unlike  fully  fledged  parametric  modelling  so<ware  such  as  Pro/ENGINEER,  CATIA,  or  even  Sketchpad,  the  parametric  rela7onships  of  Revit  are  hidden  behind  the  interface.  The  focus  is  on  using  parametric  models  rather  than  crea4ng  them.      Therefore,  while  the  majority  of  architecture  firms  may  never  use  overtly  parametric  so<ware  like  Digital  Project  or  Pro/ENGINEER,  most  –  o<en  without  even  considering  it  –  use  parametric  equa7ons  in  some  capacity  to  model  their  buildings.
