yes, and blender is quite adept at handling anything you throw at it, including BVH(with BVH hacker), on a sidde note some good hot keys for some of you
. = 3d cursor coordinate(as in rotate around 3Dcursor)
, = selection center coordinate
g = move selection
s = scale
r = rotate

now add the following
shift+z = constrains to x,y try x and y, whatever your needs

pressing (x,y,z)once constrains it to that axis in world coord...
pressing again constrains it in local coordinate

type in the required value e.g.....
press r(rotate) z(z axis) z again(local z axis) 45, press enter....

that should rotate your selection around it's local z axis 45 degrees....

another good hot key is shift+s, this is more about cursor functions....and a somewhat advanced topic. for now I will leave this post as is, if someone has a blender related question feel free to send me a PM, I have been using Blender for a long time, as well as ventilator and pappenheimer.
