I tried that but it didn't seem to work. The long faces were copied as surfaces along with the knuckle.
Hi my Friend,
You need for two small faces what will be connected to "hinge's body".
Here is a video about steps:
Thanks everyone. After @JasonTitcomb's response and my return response of confusion I had a "duh" moment and realized I was neglecting to select the face behind. When I did that it worked. But it was at the end of the day yesterday so I couldn't try it until this morning. The method I used didn't require any stitching. I just selected all the connecting faces per Jason's recommendation. But I'm going to practice the stitching method too.
@Imics, I'm going to have to study your method a bit. Pretty involved and there's the language thing. The method I used was very straightforward but your "advanced" techniques might serve for more complicated situations.
Thanks again for all your help.
