I am using Chief Architect X7.  I cannot figure out how to automatically butt ceiling joists against a ceiling beam with the same bottom height as the joists.  In other words, hang the ceiling joists on the beam.  If I drop the ceiling beam below the joists, I can make them bear on the beam, but that's not what I'm looking for.
 
	 
 
	This works for floor joists and beams, but seemingly not for ceiling joists and beams.  Am I missing something obvious?
 
	 
 
	Screenshot shows joists running "through" the beam if the beam has the same bottom elevation as the joists.
 
	 
 
	Thanks for your help.
