Component, sub-component and assembly drawings
back in the right hands a buck which the architect
should never have picked up in the first place.
It is, of course, part of the architect’s professional
responsibility to ensure that he does not specify overall
doorset sizes complete with frame dimensions which
involve expensive non-standard doorleaf sizes. Similarly,
he must have the basic technical
knowledge of joinery to ensure that he
does not ask for a frame size which
involves a third of the timber ending up
as shavings on the joinery shop floor
simply because the finished section
was just too large to allow it to be run

method may simplify the process of
building communications, but they
cannot serve as substitutes for
fundamental technical knowledge.
(See also the notes on coordinating
dimensions and work sizes in
Chapter 4.)Component drawings lend themselves
to reuse within the office more than
do other categories of drawing. One of
the advantages of a comprehensive
communications system is the facility it
offers of standardising the format of
such details, and hence enabling them
to be used direct from one project to
another. The resultant benefits in
economy and consistency are obvious
(3.5). For this reason a standard
format should be considered and the
drawing size will probably be smaller
than that used for the rest of the
project. (However, see the comments
on this in Chapter 4.)CAD of course lends itself well to this
technique of storing details for reuse,
the relevant details being held on disk
until required. The ease with which
details may be amended means that3.3 One window component?
