I have a question if it is better to model a building in viz or to model it in arch desktop.. also i have trouble importing 2005 arch desktop drawing into the student free download version of viz 2008.. any help is appreciated thankx..

Jessica, most people agree that you should model in whichever program you are more comfortable with.  Many have argued that one is better than the other, for various reasons.  I like Viz, because I know Viz better.  Others model in ADT, because they are more efficient with it. 

As far as your import problem, could you explain the details a little more?

WELL WHEN I BRING IN A DRAWING IT COMES IN IN THE LAYER COLORS.. IE: BLUE FOR WALLS .. PINK FOR WINDOWS OR WHATEVER I PUT THE LAYER COLOR AS.. I TRY TO ADD A MATERIAL TO THE WINDOW FRAME AND THE WHOLE WINDOW GLASS AND ALL TURNS TO THAT MATERIAL.. I TRY TO FIND ITS SUB OBJECTS BUT THERE ARE NONE JUST THE WINDOW ITSELF.. THERE IS NO SUBOBJECT FOR THE FRAME SASH GLASS.. ETC....  IT DRIVES ME NUTS.  I GUESS I HAVE TO MODEL IN VIZ TO GET THE MATERIALS TO ATTACH RIGHT/.

When you import the drawing, make sure in the Import Options window that
“Create one scene object for each ADT object” is unchecked.  When I did a
test with this checked, the window was one object and said “Linked Geometry”
in the Modify tab.  With it unchecked, each piece of the window was a
separate object.  Also, if it does show as “Linked Geometry” you can still
get to the Material IDs by applying an Edit Mesh, or converting to Editable
Mesh.
