Help on Symmetry

[Jedit]

Anyone tell me how to use the symmetry dimension tool

Have a part with 3 holes and 2 angular faces, see attached sketch.
I have created an alignment between holes 1 & 2 and placed the datum in hole 3.

I have measured a plane on sides A & B then created an alignment plane through the Y axis, this I called datum C. My Drawing calls for the Symmetry of the two angled faces to 0.2mm about C but I cannot get the correct answer?
The output is always zero & as a double check I have intersected the two side planes to generate a point that shows 0.011 off centre (0.022 symmetry?).

Help Guys Please??????

Out of extreme curiosity, what standard is ref'd on your drawing? (14.5, iso??)
Kev

[Jedit]

its iso, but Dat B was a mistake i made that i later deleted but did not del the ref to it in the prog.
