Boundry Calculating

I want to find the X, Y, and Z position "boundries" of a part within a library, to compare to a player, so events can be triggered when these boundries are left. If the part has not been rotated, this is easy enough (Position.Axis - Size.Axis/2 or Position.Axis + Size.Axis/2 for minimums and maximums). I understand it would probably be lookVector used in this. But I have no idea where to start. Anybody have an idea?

You mean so you can detect when something is in or out of a specified bounding box? If so... Use this information: http://wiki.roblox.com/index.php/Region3 Here: http://wiki.roblox.com/index.php/FindPartsInRegion3 Otherwise could you explain a bit more...

After re-reading your post, I realised I gave a wrong solution...

Take the lowest and highest x, y, and z values of each of the part's corners.

"Take the lowest and highest x, y, and z values of each of the part's corners. " I understand that. Hence paragraph 2 (If you want to call it a paragraph) The problem is if the object is tilted, thats not reflected in size or in position and it screws with the calculation.

The position of the corners are at Part.CFrame * Vector3.new(Part.Size.x, Part.Size.y, Part.Size.z), where the components of the vector3 are positive or negative depending on the particular corner.
