460 Interiors Copyright Goodheart-Willcox Co., Inc. The sheet size (page size) can vary among firms. Common sizes are 18 by 24 inches or 36 by 48 inches. Mini-sets of construction drawings—typically 11 by 17 inches—to easily transport to job sites. Typically, the designer produces sheets in horizontal format, and binds them on the left side. Construction documents are scaled drawings that use standard drawing conventions—such as line weights, types of lines, and symbols—to clearly communicate the design to team members. Each page of the work- ing drawings is numbered and lettered to indicate the subcontractor’s responsibility in the project. Interior designers most often reference the section illustrating floor plans, interior elevations, sections, and reflected ceiling plans. Title Block Each construction drawing, and every page of a draw- ing set, has a title block along the bottom or extreme right side of the page, Figure 13-32. The title block is typically a rectangular box that contains key project information such as the ■ design-firm name ■ design-firm contact information with logo ■ name of the client ■ professional seal(s) ■ sheet title and number ■ job number and completion date Lettering Techniques and Font Types Legibility and professional appearance is critical in the selection of hand-lettering skills and digital fonts. Manual drawings look best with hand lettering. Digital drawings look best with appropriate computer fonts. The most important aspect of lettering is its readabil- ity. Consistency in style is important. When a large set of documents is created, the same font type should be used by all creating the set, Figure 13-33. Hand lettering is an art. The more professional your hand lettering looks, the better others perceive you as a professional. Sloppy hand lettering can destroy a good impression of a great design. Use the following tips as you hand letter: ■ Make your lettering legible and readable. This is very important to avoid misunderstandings. ■ Create hand lettering that is consistent. It communicates confidence. ■ Keep the lettering size proportional to the size of the completed drawing. For construction drawings, sheet-size numbers are 1/2 inch in height and main titles are 3/16 to 1/4 inches in height. ■ Use a straightedge so your hand lettering does not slope vertically down the page. ■ Use block-style lettering with uppercase letters that are square in shape. ■ Create consistent space between letters for ease in viewing and reading. Measure the space between lines of the lettering with a ruler. ■ Study samples of lettering styles. Then practice every chance possible. Designers typically use hand lettering on schematic drawings, freehand sketching, and for informal, written client communications. Present yourself well. Charles E. Smith, Areté 3 Ltd.
