Yes, like Petr mentioned the expressions were for single-value entries (like circle radius, offset distance, etc...) and not for x,y,z point coordinates.

But for the updated Aug-4 beta I have added some initial support for expressions for points as well.

The way it works is if your decimal point separator is not a , character then you can separate the coordinates by commas like: 2+2,5,0

Otherwise a second method is to put ( ) parenthesis around each coordinate, like: (2+2)(5)(0).

Currently the way you originally tried with pieces separated by spaces will not work. I also want to support spaces inside the expressions themselves so that is a more difficult one to support. But I'll try to take a look and see if I can add that in.
