Subcomponent drawings
These have a limited use and often the information they convey will be better shown on the component drawing. There are instances, however—particularly when a range of components is being dealt with of which the sizes and appearance differ but the basic construction remains constant—when it may be more economical to present details of the construction on a separate drawing.
For example, 3.9 shows two doorsets of different sizes and types. The basic sections from which they are fabricated are similar however and that fact has been acknowledged in this instance by the production of a sub-component drawing 3.10 to which the various components drawings refer.
The method is really best suited to large projects, or to those offices which have produced their own standard ranges of component details.
