How to subtract geometries in AutoCAD

Here is a quick tutorial on how to subtract geometries in 3D in AutoCAD.

We have had great time learning how to extrude and use the REGION command with AutoCAD in this post and this post.

Today we are going to learn how to subtract a geometry.

If you had time to check the post I linked up to above, you would notice that the piece at the center of the figure was a cylinder.

The whole 3D object was a combination of the bigger object and the cylinder.

Here is how to use that cylinder to make a cut at the center of the drawing.

The command we are going to use is called SUBTRACT.

To use this command


  1. Type SUBTRACT and press ENTER
  2. Select the bigger object and press ENTER
  3. Select the object to be subtracted and press ENTER
Using these steps, Here is what I have been able to come up with.



Using the REGION command

Using the REGION command before using the EXTRUDE command changes completely the end result you get after using the EXTRUDE command.

On this article, we learnt how to use the EXTRUDE command.

But I did not mention the REGION command there and if you remember, we used this image and got the following result.


Now let's use the REGION command before extruding. 

Type REGION, select the whole objects in the drawing area and press ENTER



After this. Use the step we learnt in the last post to extrude the whole thing.


And here we have it!



How to extrude in AutoCAD

Here is a simple and one of the most used command in 3D while using AutoCAD. In fact, when you have a rectangle or a square, you can easily extrude them to get a box.

To used EXTRUDE in AutoCAD, you need to have the basic object created. I mean by the basic object, the square or the rectangle.

Here is how it works.

Let's consider the following image which we worked on in this post.


Let's extrude this figure.

I will first use the FREE ORBIT tool to get into an isometric view


Here is what the isometric view looks like


Now let's EXTRUDE.

  1. Type EXTRUDE and hit on ENTER
  2. Select the whole figure and hit ENTER
  3. Move upwards and click when the length of extrusion satisfies you



Here you go!

How to draw a straight line in AutoCAD

Here is how to make sure the line you are drawing is a straight line when using AutoCAD.

If you go on the tool bar down the main AutoCAD window, you will find the following icons.


If you activate the ORTHO mode, this will restrict all your movement in the drawing area. You then will be able either draw move vertically or horizontally.

Here is the ORTHO mode.


So. When this command is activated, you are sure that the line you are drawing will be a straight one.

I meant by straight line here, a either vertical or horizontal line though one might argue that all the lines you will draw in AutoCAD will be straight. This is true. I just need to emphasize the fact that in this post, a straight line is restricted to be either vertical or horizontal.

An oblique line would not be qualified as a straight line in this contest.

Create an arc in AutoCAD without using the ARC command

In this little and short post, we are going to create an ARC in AutoCAD without actually using the ARC command.

You will find this silly, but yes, it is doable.

How do we do it.

What if we create a circle, and cut it into two, would that be an arc to you? let's see what it looks like in real life.


After cutting the circle using the line we remain with the following.


Now we can clearly see that arc. What happen if we select it?


Yes, it is a arc. You have just learnt how to create an ARC in AutoCAD without uing the ARC command.
