I AM TRYING TO SHOWN THE PROPER WAY OF SHOWING ROOF TRUSSES ON BUILDING SECTION DRAWINGS. i HAVE A SIMPLE TRUSS DESIGN WITH A TWO FOOT TOP CHORD OVERHANG. THE TRUSS HAS A TOTAL 18" HIGH HEEL WITH AN EXTERIOR FINISH TO MATCH THE WALL BELOW. 15" OF INSULATION WITH A 3" AIR SPACE AT THE TOP PORTION OF THE ROOF. THE INTERIOR CEILING IN SOME AREAS WILL BE VAULTED. DO I MAKEUP A ROOF SYTEM THAT HAS THE ROOFING MATERIAL, SHEATHING, AND TOP CHORD  FRAMING MEMBER AND ATTACH IT TO A +/- 15"PONY WALL (TRUSS HEEL CONDITION) THAT IS ATTACH TO MY TYPICAL EXTERIOR  WALL AND THEN HAVE THE CEILING COMPONENT SHOW THE BOTTOM CHORD FRAMING AND CEILING FINISH.

Depends on how detailed you want to get.. You could make your roof with your roofing material and then make your truss as a component and manually place them where you would like them to go, or you could do as you said and create your roof with the roofing material, and top chord and place the bottom chord and heel as a component.  Its really up to you. Your ceiling will just be your ceiling seperate from the roof and trusses.

Remember - roofs layers are like floor.  They are solid in x-y directions - so chord depth could be modeled but why?  It would only be right in parallel views to the chords.  I model jut the deck up then add trusses - either model or just detail.  Usually - just detail.

Hi!

I know there are work arounds using detail lines, but if you are like me, an instructor, you want to create framing models and to have students create them so they understand framing. 

I can cobble something together and have my students mucddle through, but getting wooden structure to join cleanly is a bear

attached is my efforts - Anyone have any suggestions?

Use architectural families - not structural if you want a visual model.  There are OK truss families here on RC.
