How do I enter a straight line length in AutoCAD?This is a question that is both common and important. In AutoCAD, there are two ways to enter the length of a line, one is to drag or click with the mouse to determine the start and end points of the line, and the other is to enter the length and direction of the line through the keyboard. Next, we'll take a closer look at both methods. First of all, the method of entering the length of the line with the mouse operation is intuitive and flexible, which is suitable for situations where precise control of the length of the line is not required. The specific steps are as follows:1Enter line on the command line or press the L key to start the Draw Line command. 2.Left-click in the graphics area to determine the starting point of the line. 3.Drag the mouse or click the left mouse button again to determine the end point of the line. The command line displays the length and direction angle of the line. 4.If you want to continue drawing a straight line, repeat step 3When you're done drawing, press Enter or right-click. 
Secondly, the method of determining the length of the straight line through keyboard input is more accurate and standardized, and is suitable for situations where the length of the straight line needs to be accurately controlled. The specific steps are as follows:1Enter line on the command line or press the L key to start the Draw Line command. 2.Left-click in the graphics area to determine the starting point of the line. 3.Enter @ or press the @ key on the command line to enter relative coordinates with the starting point as the reference point. 4.Enter the length and direction angle of the line on the command line, separated by commas. For example, if you enter @100, 30 means that a straight line of length 100 is drawn along a 30-degree direction with the starting point as the origin. 5.If you want to continue drawing a straight line, repeat steps 3 and 4;When you're done drawing, press Enter or right-click. As an example, if we want to draw a square, we can use the second method to enter the length of the line. Assuming that the sides of a square are 50 long, we can follow these steps:1Enter line on the command line or press the L key to start the Draw Line command. 2.Left-click in the graphics area to determine one of the vertices of the square. 3.Enter @50,0 on the command line, which means that a straight line of length 50 is drawn along the 0 degree direction with the vertex as the origin. 4.Enter @50 and 90 on the command line to indicate that the end point of the previous line is the origin, and draw a line with a length of 50 along the 90-degree direction. 5.Enter @50,180 on the command line to indicate that the end point of the above line is the origin, and draw a line with length 50 along the 180-degree direction. 6.Type C or press C on the command line to close the square. 7.Press Enter or right-click to end the command to draw a straight line.
