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.
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.
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.
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.
You can see on the picture where you can find Subtract (you can always type it).
Click on the command.
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.
After that it will ask you to select solids,surfaces and regions to subtract,that is the pyramid,click on it and press Enter.
This is what we have got now,a nice cut in the ball.
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.
