Hello.

I am trying to evaluate the symmetry of 2 holes to a cylinder (datum A). I have created a point at each hole with COLPTS and then created a midpoint with SYMPNT. I believe I now need 2 constructed planes or axes, offset equally from the cylinder origin.

How do I create offset theoretical planes or axes?

Also on the symmetry input form, there are inputs for "Axis" and "Projection plane". Do I need to specify something in these as my datum is a cylinder?

Thanks.
