How to draw a perspective in autocad

Updated April 17, 2017

A perspective view of an object is a view that shows at least two edges of a shape or object that are parallel to each other. These edges must appear to be converging toward each other as they extend away from your line of sight. Drawing a perspective view in AutoCAD involves using a number of commands, including the "Perspective" command. Other commands needed to produce a perspective view include those for changing the viewpoint with which you look at an object. AutoCAD has several such commands. The "3dorbit" command is one of the most commonly used.

Type the "rectangle" command, and then press "Enter." This command puts AutoCAD in the mode for drawing rectangles. These shapes are effective at demonstrating a perspective view because they have two sets of parallel lines. You'll see those lines converge in Step 2 to "Perspective" mode.

Click anywhere in the viewport to place the rectangle's first point, and then drag to size the rectangle. Click again to finish the rectangle. Notice that its sides are parallel. You're looking at the rectangle in "Top" view, which is not a perspective view.

Type "3dorbit," and then press "Enter." This command tells AutoCAD to orbit the viewpoint in 3-D space, based on your mouse movements.

Click the left mouse button and drag to orbit the viewpoint. Notice that at least two of the rectangle's sides appear shorter than they did in "Top" view. This effect is called "foreshortening." Notice also that the rectangle's opposite edges are still parallel. This means you're not yet looking at a perspective view.

Type "Perspective," and then type "1," which tells AutoCAD to generate the perspective view. Notice the rectangle's parallel edges are no longer parallel. They appear to converge toward each other, which is the characteristic sign of linear perspective.

Click the "View" menu, and then click the "Orbit" heading.

Click the "Free orbit" command, which lets you rotate the current viewpoint to create a perspective view.

Click the left mouse button and drag until the "X," "Y," and "Z" axes in the lower left corner of the screen are all visible. This tells you that you'll be able to see the width, depth and height of the box you'll draw next.

Click the "Home" tab, then click the "Box" button in the "Modeling" tab. The "Box" command lets you draw 3-D boxes, which demonstrate clearly the phenomenon of linear perspective.

Click in the viewport, then drag to define the bottom of the box.

Click again to finish the box's bottom, then drag up to grow the box's height dimension. Click again to complete the box. Notice that all opposing sides of each edge of the box are parallel. This means the viewpoint is not yet a perspective one.

Type "perspective 1" to turn on perspective. The box's opposing edges no longer appear parallel, indicating that you've created a perspective view.
