Working in3D usually involves the use of solid objects. At times you may need to combine multiple parts into one, or remove sections from a solid. AutoCAD has some commands that make this easy for you. These are the Boolean operations as well as some other helpful commands for solids editing.
The Boolean operations are to create complex solid models out of primitives. The following tutorial shows you how to use Intersect, Subtract, and Union operations.
Intersect: Defines a new solid object based on the common volume between selected solids.
Union: Defines a new solid that consists of common and uncommon volume between selected solids.
Subtract: Select two set of solids. A single solid based on the removal of the second set from the first one will be created.
All the above operations will eliminate the original solids.
Boolean Operation is used to Subtract one3d object from another3d object.
