Howdy, hope all had a wonderful holiday.

I'm doing pretty good at Photoview 360 2010, but one thing is escaping me.  I want to place a model on a table top, or countertop in the environment.  Moving the floor height has more or less no effect.  Or, I'm having no effect.  What is the procedure for this?  I have researched all the tutorials on the Photoview web, gone all through the help pages and I can't seem to find anything directly related to this topic.

Many thanks
