# A few questions about Region3?

I just discovered Region3 exists and I think I it's important since I've been using the .Touched event from Parts to define a "region". I can't find much info in roblox docs so here are a few questions:

1) What "shape" is this region? A block? A sphere?

2) If it is a block can I make a region3 sphere?

3) What is min and max in Region3.new( Vector3 min, Vector3 max ) <- taken from https://developer.roblox.com/api-reference/datatype/Region3

4) How often is this used in a game? (because I haven't used it at all)

1) Rectangular Prism. 2) Create a fake sphere that fits inside the region and do some checks to see if the player inside the region is inside the fake sphere using magnitude. 3) min is the lower corner extent, max is the upper corner extent. 4) I can't think of any cases I've seen it used but that doesn't mean you shouldn't use it.
