ARCHITECTURAL DRAWINGS Architectural drawings may be classified as follows: Preliminary drawings are small studies of the proposed new work, freehand or otherwise, at a small scale, finished in an attractive man ner. There are three classes of preliminary drawings—namely, Sketches, Perspectives, and Competitive Sketches.

Preliminary Sketches. In architectural work, no matter whether you are an architect dealing with an owner or client, or a draftsman getting out working drawings, it is always better to make a preliminary sketch of the arrangement, detail, etc., as it saves time and much erasing and changing on the scale drawings. By pre liminary sketches we mean the sketching free hand on paper to show exactly just how you will draw it with the T-square and triangles.

Let us consider the architect dealing with a client. The first thing is an arrangement of the rooms, or the plan is first studied. For this work, tracing paper will be found very easy to work with and very convenient. The use of a sheet of co-ordinate paper under the tracing paper will be found very convenient. The squares on the co-ordinate paper will serve as a guide in drawing straight lines; and also the squares as ruled on this paper can be used as a scale—one square representing one unit, as a foot or an inch.

Very often the owner of the proposed new building will have some scheme or arrangement of rooms that he would like; therefore, try to have him give you a rough sketch of such arrangement; even a drawing with single lines for walls, and cross-lines indicating windows, will be very helpful. A drawing as shown in Fig. 2 is just what you want from your client.

Having received either this sketch or a list of the requirements, you are ready to start your preliminary sketches. Spread down the co-ordi nate paper, and over this lay a sheet of tracing paper. These may be held down with thumb tacks or weights of some sort placed on opposite ends. Assume each square of the paper to represent some unit, as one inch, or one foot, or ten feet; and lay out first the property lines.

Then commence on the building proper. Make no attempt at trying to make exact lines; let these sketches be more of freehand drawing. Mark off the approximate sizes of rooms by rectangles, and try the various arrangements, endeavoring to secure an ideal arrangement. Make no attempt at trying to show double lines for wall lines; let it be a free and easy sketch of single lines.

Architectural Drawings

Don't be satisfied with one arrangement of the given requirements. Over this first sketch lay another sheet of tracing paper. Perhaps you can use some parts of the first sketch, and revise other parts. Study your problem, and be fully acquainted with the requirements. After completing this second arrangement, try to imagine difficulties that this arrangement would present, and how they might be remedied. Make another sketch; don't be satisfied until you have made half a dozen different sketches. After having considered all the possible arrange ments of the requirements, then take the sketches, spread them all out before you, and see if you have solved the problem.

Now commence with a clean sheet of tracing paper over the co-ordinate paper, and make fin ished sketches; that is, lay out the wall lines carefully, put in the windows and doors, letter the rooms, and get these drawings into shape to submit them to the client. Make them so that he will understand clearly the arrangement you have sketched.

For filling in the walls to indicate the walls and the windows, it will help the appearance to color the walls on the back side of the paper with the pencil. This gives a subdued color to the walls, and increases the clearness of the plan or drawing.

Prepare small sketches of possible treatment of the elevations, and submit these also with the plan. These will now do for you to submit to your client (see Fig. 3). Be very sure that you have studied the problem thoroughly, and be prepared to answer all questions your client will probably ask. The client will very soon form an opinion of your ability by the way you handle his work.
