DRAUGHT, in architecture, the representation of a building on paper, explanatory of the various parts of the exterior and interior, by means of plans, elevations, and sec tions, drawn to a scale, by which all the parts are represented in the same proportion as the parts of the edifice intended to be executed. All the horizontal parts are explained by plans; the faces of the'vertical parts are represented by elevations and sections ; particularly, when the plane of delineation is parallel to the faces to be represented. The vertical dimen sions of buildings upon circular and polygonal plans are understood from the elevations and sections. In complex buildings, besides the general plans, elevations, and sections, a set of drawings should be made to show the detail of the small parts.
In addition to the drawings which are used in conducting the work, a perspective representation of the exterior should be furnished by the architect, in order to show the general appearance and effect of the intended edifice to the employer, and perhaps, in some instances, two or more perspective representations will be necessary, in order to bring more parts into view, which should be drawn to such points as those in which the building will be most generally seen.
When several stories of a building differ in their construc tion, each story requires a separate plan. The sections are generally parallel to the sides of the edifice, taken through the most complex or principal part. Most buildings require at least two sections, some many more. When the sides of a building are dissimilar, as many elevations will be neces sary as the edifice has sides.
The number, the form, and disposition of rooms are shown by the plans. The architect who gives the design of a build ing, ought to be well acquainted with the constructive parts of carpentry, masonry, and bricklaying, before he commits his ideas to paper, or otherwise he may be liable to public censure.
