The kind of thing I mean is shown in the attached image. How can I line up the two yellow axes drawn on the two parts shown? Using the mate constraint doesn't work. Is there a different way of achieving the desired effect? i.e. middle of one part mated to middle of another part? <IMG src="https://forums.autodesk.com/t5/image/serverpage/image-id/186695i5BD27B2C604D04E8/image-size/original?v=mpbl-1&px=-1" border="0" alt="line-up-axes.png" title="line-up-axes.png" width="415" height="428" />  I'm using Inventor 2015 Wed, 02 Sep 2015 08:54:16 GMT Anonymous 2015-09-02T08:54:16Z
