Search for ADD_CHK_PARAM in the Modelcheck user guide.
This will allow you to create a parameter that stores the outcome of another check.
(Not sure if it woks for model size, havent tested it)
In my company we capture the outer x/y/z dimensions of a part by referencing exisiting model dimensions in a set of relations that writes the result to a designated string parameter.
You can also use a note parameter to do the same, however, as far as i know, note parameters can not be designated if that is a requirement.
