Karim,

Not all truss manufacturers are alike. That's why this last one you have seems
to be the exception to the usual way you have been doing it.

By the way, the roof trusses I'm talking about are the open-web steel
joist,designed and fabricated  based on the standard  specifications of the
Steel Joist Institute for open web steel joist. These are shown on UBC1994,
Chap.22, Div.III................

In a book titled "Designing with steel joist, joist girders and steel decks by
Fisher, West and Van de Pas, it says.........."The establishment of the
Standard Specifications for Steel Joists allowed building designers to specify
rather than design a structural component of the building frame. The
acceptance of the Standard Specification by the building codes and building
officials, allow the use of steel joists in buildings without the need to
reconfirm by engineering design the sizes and materials used in joist
conforming to standard designations for given loads and span."...............

In a Steel Joist and Joist Girder catalogue by VULCRAFT, they claim that
they....."do not accept the responsibility as the design professional of
record for any structure......they accept the delegation of the engineering
responsibility only for the products it manufactures............they provide
engineering for the  design of its products and do not displace the need on
any project for a design professional of record...........

Any plan checker  or truss engineer out there  who can comment on these?
