Lesson  5:  Parametric  Modeling  in  Fusion:  from  2D  to  3D  In  this  lesson,  you  will  use  the  parametric  sketch  of  the  Reciprocating  Saw  Trigger,  which  you  created  in  the  previous  lesson  to  begin  solid  modeling.  Using  the  sketch  you  will  Extrude,  Fillet  and  join  the  two  bodies  to  create  a  solid  model  of  the  saw  trigger.  At  the  end  of  the  lesson,  you  will  consider  when  and  learn  how  to  apply  Physical  Materials  and  assign  Appearances  to  your  3D  models.    

Tutorial  Video  1:  Extrude  the  2D  sketch  to  3D  model  the  saw  trigger.  Watch  this  video  to  learn  how  to  extrude  and  3D  model  the  Reciprocating  Saw  trigger  sketch,  using  an  attached  canvas  image  for  reference  in  Fusion  360.    After  completing  this  lesson,  you  will  be  able  to:  

• Extrude  the  trigger  sketch  to  create  two  bodies.      • Add  fillets,  combine  and  organize  bodies  in  the  Browser.      • Use  the  attached  canvas  image  for  reference.
