Boolean Operations
There are three Boolean operations defined in AutoCAD 3D, which are given below:
- Union
- Subtract
- Intersect
These three icons are present on the ribbon panel, as shown below:
Let’s discuss each in detail.
Union
The 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:
Subtract
The 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:
- Select the Subtract icon from the ribbon panel.
Or
Type Subtract on the command line or command prompt and press Enter. - Select object 1.
- Press Enter.
- Select object 2.
- Press Enter.
The object will now look like the below image:
Intersect
The 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:
- Select the Intersect icon from the ribbon panel.
Or
Type Intersect on the command line< press Enter. - Select object 1 and object 2.
- Press Enter.
The overlapping part of the remaining object is shown below:
