In CAD drawings, the most important things are dimensions – distances (lengths) and areas – and these must be accurate to the highest degree. Using the query tools provided by CAD, we can accurately determine the precise data depicted in the drawings, thereby ensuring the accuracy of our work. Next, we will take an example to look at the specific steps. I. Three common methods for measuring distance: 1. Enter the shortcut key “DIST” directly in the command line at the bottom” ； 2. In the menu bar, select “Tools – Query – Distance” in sequence” ； 3. Click the “Calculator” icon in the toolbar above, and in the calculator that appears, click the “Distance between two points” icon. II. Example: Measuring the length of a line segment. As shown in the diagram, there is a line segment on the drawing that does not have any dimensions indicated; we need to measure its length. First, enter DIST in the command line. After the message “Specify the first point” appears, click one of the endpoints of the line segment on the drawing, and then click the other endpoint. The exact dimension value will then be displayed above the line segment. III. Example: Measuring distance. For instance, there is a rectangle and a line segment in the figure; what is the vertical distance between the rectangle and the line segment? In the menu bar, select “Tools – Query – Distance” in sequence; then click on the endpoint at the lower right corner of the rectangle, and after that click on a point on the vertical line segment, and the distance data will be displayed. IV. Three ways to measure area: 1. Enter the shortcut key “MEASUREGEOM” in the command line; 2. Select “Tools – Query – Area” sequentially from the menu bar” ； 3. In the “Query” toolbar, click directly on the “Area” button. 5. Example: Measuring the area of a rectangle. Given that the English terms in the command line are difficult to remember, we will use the second method here: select “Tools – Query – Area” in sequence from the menu bar. Then select the four endpoints of the rectangle one by one. To avoid mistakes, it is recommended to select the endpoints in order from left to right and from top to bottom; this way the entire rectangle will turn colored. After pressing Enter to confirm, a data frame will appear below showing the area and perimeter. These are the five methods for measuring distance and area using CAD.
