CAD 1201-51 Drawing 1 - Fallingwater (On your first day?) Fallingwater Trace Other files utilized: rlclogo2010.dxf, fallingwater.jpeg For your first drawing, you will be asked to do two things that will not be allowed throughout the course of this class: trace and draw without precision with regard to scale and measurement. Consider the basic principle behind AutoCAD; draw. How is it that most people learn to draw? By tracing and studying existing works to know the subject better. I remember my first day of CAD class. We were asked to draw a basic stick-figure type house, sun, and tree. If you were adventurous, you might use a few hatches on it. The goal here is take that one step further, with a true goal and use many new commands right off-the-bat. Then, there was even room for a little history lesson with the drawing. Many technical drawings for diagrams or instruction manuals may be created using photos (fig.1.4) and AutoCAD. The goal is to trace-off a lineart CAD drawing of Fallingwater and give it a little color by using the Hatch or GRADIENT tools. Fallingwater is justifiably one of the most celebrated works of Frank Lloyd Wright. Designed as a weekend home for a wealthy family, the house artfully integrates architecture with the natural setting. By placing the house over the waterfall, Wright insured that the splash of water could be heard from anywhere inside the house but seen only by going outside, where the horizontal cantilevered concrete balconies and rough textured vertical stone piers establish the backdrop for the cascade, just as Wright intended. Few architects in modern times have equalled Wright in his ability to design with respect for the land. Some of the commands meant to be utilized with this exercise are: Line, SPLine, PolyLine, COpy, ARRAY, DIVIDE, Move, COpy, ROtate, EXtend, TRim, IMage, SCale, SKETCH, Hatch, Text, ORTHO & GRADIENT. This drawing should you become familiar with creating and modifying objects. You are not bound by measurements or specifications. Take advantage and try to have fun. Colors and layers are up to the user. **Warning** You never know when I may ask to see your Layer Properties Manager (LA) and how well objects are organized on each layer. Start the drawing off by using your new template file with titleblock on an A size sheet. Use the IMage command to place the provided Fallingwater photo into the CAD file. This can also be done by clicking on the flyout for the References tab of the Insert panel. This will gain access to the External References Manager (fig. 1.2). SNAP and place the image into one of the upper corners and stretch or scale it to make the image fit the width of the drawing border. Put the image on its own layer to have the ability to hide it at any time to preview your line drawing or sketch. The image can be adjusted or clipped at any time. Adjustments include changing the image s brightness, contrast, and fade. Increasing the Fade value will allow you to see your tracing more easily. The correct color of choice will also make it easier to understand. Double clicking on the image will bring up an Image Adjustment dialog that also has a preview (fig. 1.3 ). When an image is selected, you will notice a contextual tab on the RIBBON that allows for most adjustments (fig. 1.1). An image can be clipped to hide certain areas. Use draw commands like line or polyline to trace over the top of the image. When you finish the drawing, turn off the layer with the image on it to reveal only your tracing. After tracing off the image, fill in areas using a Hatch or GRADIENT. Export the drawing as a PDF file and copy to the desktop of the instructor s PC. Make sure to keep a copy in the.dwg format as well. You are not expected to draw something as elaborate as fig. 1.5, but it would be good practice. 2

Figure 1.4 Notice the tree breaking the border. For a working drawing this is not appropriate. However, for a presentation drawing, this will add interest and design. I encourage you to present and design outside-the-box, but working drawings should be kept professional. REND LAKE COLLEGE DRN BY: (INITIALS) CK BY: TA DR. NO: 1 TRACING DATE: SCALE: FIT Figure 1.5 4
