Student Activity Using the software, create the drawing and produce your own architectural blocks using the drawing set-up and the commands that have been demonstrated to you. In this activity and in the small shed drawing in the Drawing of a Simple Building (Architectural CAD) activity, all units will be done using imperial measurement. The settings for the drawing will be architectural in the units dialog box and the dimstyle dialog box. Your assignment is to draw all of the drafting symbols in Figure 1 below (you do not need to draw the labelled leaders). Figure 1 Switch symbol. A switch symbol is just the letter S inserted as a text object. The height of the text should be 4". Type TEXT. Follow the prompts by pressing Enter for each one until you get the prompt to click on the location where you want the S to be placed. Three- and four-way switches are noted with superscripts, for example S3 and S4 in AutoCAD 16 or by typing the number S3 or S4 in the same text entry box in other versions of AutoCAD or other software packages. Door symbol. The door symbol is made with a 36" vertical line. The arc of the door is made by using the circle command. The centre of the circle is started at the bottom end of the line with a radius of 36". A line must be added to trim out three-quarters of the circle. This is done by drawing a line starting at the bottom end of your first line and drawing it horizontally through the circle any distance. Type TRIM, press Enter, select the lines and the circle, and press Enter. Then pick the parts of the circle you want to trim out and delete the extra line. Two vertical lines 6" long should be added to the end of the arc and the base of the door to represent the thickness of standard walls as they are in all new frame construction (Figure 2).
