# Setting the zero point to an exact integer

When I set the zero point to an intersection of two guide lines, I often find that it is out by exactly 0.088mm.  How can I set the zero point to an exact number of mm?

What makes you think that's off? What are you comparing to?

.088 mm is the rounded value ID uses when converting .25 pt to millimeters, and I suspect you are seeing the result of including stroke weight in frame dimensions.

There aren't any frames involved.  If the zero point is at the top left corner and I insert horizontal and vertical guides at, say, 10mm in from top and left side, then drag the zero point to the intersection of the two guides, clicking on the two guides reveals that they are now at -0.088 instead of zero.  I accept that 0.088mm is not a huge error, but it still niggles me.

OK, I don't see that here. Did you verify that the guides are exactly where you said, and that you really dropped the zero-point on the intersection? I've found CS6 to less than stellar in snapping so it pays to watch the numbers as you drag.

Yes, the guides are exactly on  the 10mm marks.  I drag the zero point to the intersection, watching the numbers and making sure they are at exactly 10,10 before I release the mouse, but the guides still show as -0.088mm.  Occasionally the zero point will drop exactly at 0,0 - but usually it does not.

I suspect it's a matter of the mouse or trackpad, but I can't say for sure. As I said, it seems to work correctly here, but I frequently find things that I thought were snapped to guides or other objects that turn out not to be in CS6. My only workaround is to double-check.
