Hi all,

I am trying to rotate a selection about an arbitrary axis which does
not pass through the origin. It looks like 'trans' routine can give me
the matrix i need, but i can't figure out which combo of axis, offset,
center, and origin will do the trick.

let's say i want to rotate 20 degrees about the axis {1,1,1} passing
through the point {0,0,1}. can anyone give the trans command that will
give me the matrix i seek?

thx very much,
Ed
