virtual condition - resultant condition
if these definitions, can somebody tell me what constant and variable mean? thanks
1. virtual condition - a constant boundary generated by the collective effects of a size fearures's specified mmc or lmc material condition and the geometric tolerance for that material condition.
2 resultant condition - the variable boundary generated by the collective effects of a size feature's specified mmc or lmc material condition, the geometric tolerance for that material conditon, the size tolerance, and the additional geometric tolerance derived form the feature's departure form its specified material conditon.

check out page 30 of the asme standard for a better definition of vc and rc. krulikowski's book has a great illustration of the two as well.
