Where to Ask?

I don’t know enough about Blender to know exactly where to ask. My goal is to model a part of a building which I can then cause to shatter into many fragments (subjected to gravity and bouncing off other objects as if exploded with a bomb. Can someone tell me if this is done with particles or the rigid body game engine or where. I just need a starting point. Thanks

Blender comes with an add-on called Fracture tools but its not enabled by default

Shatter looks like it should work, I’ll give it a try.
