i cannot insert a reference to a feature
i insert the reference that i want to be asked when i insert the feature to a part, but when i insert the feature that reference isn't at the list of the references that should be determine so as to position the feature into the part. what am i doing wrong??
basically i want to mate two planes. perhaps my way to achieve it is wrong...does any have an idea what i should do?? thanks in advance!
