Subtract tool in AutoCAD

This tutorial will be about subtract tool in AutoCAD.
I will show you how to use this tool when you do 3D modeling in AutoCAD.

  1. Step 1:

    Now, I am gonna use a sphere (ball) which you can see on the picture for demonstration of the subtract tool.

    You can draw something else.

  2. Step 2:

    You need to have 2 bodies to preform subtract command,so my second body will be this pyramid.

    What is actually a subtract tool you may ask?

    Subtract is the command which allows you to cut one body by using another body.

    I will show you that in next steps with these bodies on the picture.

  3. Step 3:

    Make sure that you have pyramid inside the sphere,It does not need to be like on the picture,I just want to show you what this command does.

  4. Step 4:

    You can see on the picture where you can find Subtract (you can always type it).

    Click on the command.

  5. Step 5:

    It will ask you to select solids,surfaces and regions to subtract from.

    I will select the ball (sphere,call it however you want) because I want to make a cut on the ball.That cut will have the same shape as the pyramid solid.

    Click Enter after you select the ball.

  6. Step 6:

    After that it will ask you to select solids,surfaces and regions to subtract,that is the pyramid,click on it and press Enter.

  7. Step 7:

    This is what we have got now,a nice cut in the ball.

  8. Step 8:

    If we selected the pyramid as a body to subtract from this is what we would get.

    I hope you understand how subtract works,it can be used for more advanced cuts which cant be done just by using press-pull command.
