Boolean OperationsThere are three Boolean operations defined in AutoCAD 3D, which are given below:
These three icons are present on the ribbon panel, as shown below: Let's discuss each in detail. UnionThe Union command is used to combine the selected 2D regions or 3D solids by the addition. The selected parts are combined to form a single region, surface, or solid. But, we are required to select the parts of the same object. We can select two or more parts to combine it into a single region, solid or surface. Consider the below image: Here, the two solids are selected to form a single solid. Let's understand with an example. Consider the below figure: The steps are listed below: 1. Select Union icon form the ribbon panel. Or Type Union on the command line < press Enter. 2. Select object 1 and object 2, as shown below: 3. Press Enter. The combined object is shown below: SubtractThe Subtract command is used to subtract the selected 2D regions or 3D solids by the subtraction. Consider the below figure: Let's understand with an example. The steps are listed below:
The object will now look like the below image: IntersectThe intersect command is used to create a 2D region or 3D solid formed by two overlapping regions or solids. Consider the below image: Let's understand with an example. The steps are listed below:
The overlapping part of the remaining object is shown below:
