Hey everyone, 
  
I am new to CAD construction design products and need a little advice.  I have HD PRO 2017 on a MAC.  I wish I would have gotten this a LONG time ago!   
I love the program, but am having a definite learning curve.   
I am having trouble with using multiple exterior surfaces.  Ex.  when I change the siding product on one wall, they all change.   
How can I change the exterior product per wall?  I want to use a variety of products on different walls for creativity and appeal.   
  
Also, any suggestions on working with ICF foundations and what to use for the exterior finish, on walls not buried? 
  
I find that the tutorials are rushed and find myself doing a LOT of rewinding and reviewing. 
  
Thanks!
