How to extrude in AutoCAD

In the numerous commands that AutoCAD provides, there is also the Extrude command. It is used for creating 3D objects in a solid form that is enclosing the area or to create a 3D surface from the object that has opened ends.

Many people use AutoCAD for their work, and they are familiar with this command. But, if you are not using this program daily, you must have been asking yourself how to extrude in AutoCAD? In this article, we found some answers for you, and we will represent them in the following, so keep reading.

What is the Extrude command for?

Most simply said, the Extrude command allows you to turn the 2D objects into 3D objects by giving the object a hight dimension. The Extrude command is one of the numerous 3D tools that are available in AutoCAD. As you already know, this is one of the best programs for creating and editing the drawings. Applying the Extrude command at the 2D object and entering the fitting dimensions, you can easily turn it to the 3D object in your drawing.

Create an extrude effect

To start, here is what you need to do. At first, open the new page for drawing. Head to the menu in the upper right corner, and set in on the 3D Modelling option.

In the following, you should set the Isometric view by rotating a View Cube. This is a navigation tool. To change 2D objects to 3D, you should set the isometric view because that is the way how to get a better look at the objects and to have a more realistic picture.

Now, set the isometric view by rotating View Cube can be done if you press and hold the left button on your mouse. Easily move your mouse until you finish setting the isometric view. As soon as you do that, you will be able to have a realistic image of how the objects will be looking in reality.


You are now ready to create the 2D object that you will extrude in the following. You can apply the Extrude tool only on the closed objects such as square, circle, rectangle, arcs, arcs lines, planar surfaces, planar faces on solid, ellipses, traces, regions, or any other specific shape that is making a closed object.

When you have created the 2D object, you can start the Extrude command. This will result in transforming the 2D object to the 3D. to start the command, you can type in the EXTRUDE to the command line or find the Extrude tool under the Solid Tab. Open the Solid panel and head to the Extrude option. The icon you should choose looks like an object with an arrow above.

Now, select the specific object or specific edges on the object that you want to extrude. The next step is to set the height. After you enter specific dimensions, confirm it, and the Extrude option will be applied, and you will have the objects deleted or changed in the way you set it.

Using the path to extrude object

You can use some objects from your drawing to have a roll of the path that is going to be used to extrude a specific object. So, you can use lines, circles, arcs, ellipses, helixes, elliptical arcs, 2D polylines, 3D polylines, edges of surfaces, or edges of solids as a path to extrude specific object. There are sub-options under each of these elements for extruding.

To use a path for extruding, you should make a drawing, and then activate the Isolines command. This command is specifying the number of lines that will be extruded. Then, squeeze the Enter key on your keyboard, and then click on the Extrude button.

Now, select the object and hit the Enter key again. Pay attention to the sub-options under the elements we mentioned, and choose one of them or simply type in the object’s height. While setting the extruding, you can use sub-options to determine the angle that extruding will be done under, the direction of extruding and path where extruding will happen.
