Extruding a sketch, in simple terms, is taking it from the 2D profile, and converting it into an editable 3D body. For example, If you have the 2D drawing of the profile of a simple box, you have the length and width but not the depth. Extruding the profile allows you to add the desired depth and as such, you get a very clear idea of what your component (in this case, the box) will look like in real life.
In this tutorial, we will show you how to create a sketch and extrude it on AutoCAD.
Open the AutoCAD application on your Desktop/Laptop.
Create a new file. You will now see the blank workspace.
For this tutorial, let’s create a circle and extrude it.
Click on the ‘Circle’ option from the left-hand side toolbar.
Left Click on the workspace and drag to create a circle of any dimension.
Now, on the Left-hand side toolbar, click on the ‘Modelling’ tab.
Before we extrude, head to the view cube and click on the ‘Home’ button to view the 3D view.
Now, click on the ‘Extrude’ option from the modeling tab.
Left Click to select the circle sketch.
With the circle selected, Right Click on the circle and click on the ‘Enter’ option.
Drag the circle upwards or downwards to create a 3D extrusion. The resulting body will be a cylinder.
The extrusion will be displayed in the ‘Wireframe’ mode.
Click on the View button from the top toolbar.
Click on the ‘Shaded with edges’ option.
You will now see the 3D body version of the extrusion.
This is how you can sketch a profile and extrude it on AutoCAD.
