Boolean objects fast?

How to Boolean objects quickly in Blender 2.9?

If you do not have Hard Ops addon, this is probably the quickest way I have found to boolean objects in Blender.

1. Go to the preference and under the Add-ons, look for the Bool Tool.

2. Once your add-on has been installed. Simply click on your main object and then the target object.

3. Then press Ctrl Shift Num – to create a subtraction boolean.
Other short cut keys include:
Difference – Ctrl Shift Numpad –
Union – Ctrl Shift Numpad +
Intersect – Ctrl Shift Numpad *
Slice – Ctrl Shift Numpad /

What is the boolean modifier used?

When it comes to 3D modelling, the boolean modifier is a useful tool to quickly carve areas in objects with another object. This modifier can also be used to intersect or union objects however it’s not commonly used for this purpose. While the boolean modifier is very fast to get you shape you like, this trade-off means the model will have n-gons. Still perfect for the object you do not need to apply rigging or deformers for animation.
