Hello,

I am trying to make an interal thread library.  I have it located by the edges since it will be different in every part. the problem i encounter is that since it will never be sitting on a stanard plane always moving around i made a reference geometry plane to the center of the hole but when i try saving it as a library feature part it will not let me seleceted the reference geometry thus not alowing the swept cut for the threads. Does anyone have ideals how to work around this?
