Centre 2 circles on a rectangle

[fabian]

Hi
I've had xara for some years now but never really used it extensively, but because I was having difficulty getting answers to my enquiries in other software packages I'm trying this one as a last resort.

I have a rectangle 63.5mm wide and 114.3long and I want to position 2 circles (each 8mm in diameter).

The circles are grouped to keep them 51.92mm apart.

The top of either circle needs to be 8.10mm from the top of the rectangle and 6.59mm away from either side of the rectangle, this keeps both circles squarely in the middle.

Thanks a lot for your help.

Michael
