Non parallel side holes through a disc

[David Overington]

Hello all,

I've modelled a 3D flat disc with a milled hole horizontally through the disc vfrom one side to the other. I now need to add two more non-parallel drilled holes, so that looking down on the flat disc the drilled holes would form an equlateral triangle. But I can't figure out how to specify that the additional holes start / end 120 degrees around the out disc face (rather than 90 degrees, 180 degrees or 270 degrees).

Help much appreciated,

Thanks

Dave
