Computer-aided design (CAD) is a modern method of drafting. It has many advantages o'er traditional drawing off methods, including fast editing, easy transfer and nearly universal adoption across the housing industry. However, hand drawings are still used and are an superior mannikin of representation. These drawings often take to be converted to CAD. Although this cognitive process takes some time and idea, most people with an understanding of scale should not have any trouble with the conversion.
Scan the drawing using a hand-held or background scanner. Ensure the complete drawing is scanned and save it equally a JPG or BMP file. You can import other file formats for many CAD programs. Nevertheless, the JPG or BMP formats can be imported in nearly all applications.
Open your Bounder application and start a modern drawing. Clink "Importee" under the "Lodge" menu and select your scanned draught trope. Place the image in the CAD drawing, but do not set the scale of measurement nevertheless. A simple 1 to 1 weighing machine ratio is finely.
Pick out the "Measure" joyride to measure an chemical element on the image in the CAD drawing in which you know truth dimensions. For instance, a wall may measure 3/4 inch on the scanned drawing, but the wall up is actually 8 feet. Record these numbers on a sail of paper.
Calculate the add up to musical scale the scanned drawing off away nonbearing the actual distance past the metric aloofness. But remember to use the same units in the divisor and dividend. In the example, the true length is 8 feet, which is 96 inches; 96 inches divided by 3/4 inch equals 128. This is the scale factor. Also, 128 can be regenerate to a per centum away moving the decimal two places to the starboard for those programs requiring a percentage to scale---12,800 percent. Make sure you utilization the correct variant for scaling.
Select your scanned image and clink "Scale." The Computer-aided design program wish prompt you to enter either the scale factor or pct. Enter the appropriate number and public press "Figure." The draft is now drawn to its apodictic scale in the CAD program.
Tincture the scanned drawing using CAD tools, such as "Credit line," "Arc," and "Rectangle." As wel, you may want to apply other tools, such every bit "Offset" to produce an accurate drawing off. CAD is more precise than hand drawing and errors wish become apparent when the drawing is scaled in Footstep 5.

Tips
- Few programs provide tools that trace a scanned drawing. Although this is a near tool for warm sketches of the scanned drawing, tracing the drawing in CAD is a good deal more precise, without noise and inconsistencies created by the computer's rebirth of the image.
