Hello,
 
	I am a beginner using Chief X8 and its got me stumped.  The plan I am working on is a rambler with a basement and 18" floor trusses.  When I add a floor truss to the plan and open a cross section the truss displays at the wrong height.  The top of the truss is flush with the top of the subfloor plywood and there is a gap between the bottom of the truss and the drywall.  If I change the truss to an I joist it displays at the correct height.  What am I missing?
 
	Thanks,
