Two sketches not fully defined. Where is (are) the problem(s)?

Looks good

@john_mcclary - I run into a problem the moment I click "Assembly."  There is a difference between your video and my document.in the way the instances are listed. I'm going into a lot of detail to try to explain this. I hope you can bear with me. 
 
We start at the same place with Features (except that I have 3 more Features because I had to use two more sketches and one more plane to make the extrusion of the inside plate). Parts are the same. Just for the sake of references I am giving the link. At 33:14 in your video you click assembly, this is the display on the screen at that moment. https://www.youtube.com/watch?v=sNiFlcmAD08&list=PLwCY0cZvkCFGsJ7Wf0wLcutTsDCE559iS&index=15 . On mine - https://cad.onshape.com/documents/0bbf27f22991a4360e0d803c/w/a75143c25ed83c5633f36f2c/e/a54ec3d189de45b50578c29f  

A couple of seconds later at 33:17 you are in Assembly and your cursor is at Instances and on "inside Plate" which is in red and there is an Onshape note  up saying "inside Plate <1> has an error Failed to Resolve Instance"  https://www.youtube.com/watch?v=sNiFlcmAD08&list=PLwCY0cZvkCFGsJ7Wf0wLcutTsDCE559iS&index=15  When I click on Assembly I have the Inside Plate shown as Part 2 - not as Inside Plate. I know it is the same plate but in one case it is from Features and in the other it is taken from Parts List.  .https://cad.onshape.com/documents/0bbf27f22991a4360e0d803c/w/a75143c25ed83c5633f36f2c/e/526b157aa1c1e27af117126c

There may be another difference on the display of the beam. I can't see if the plates are absent or hidden in your video. I know that in my document the plates show on the beam. I know this is significant but explaining it is a little harder so I'll just leave it at that for now. 

Also in Mates you got the Group Feature and I didn't. 

You are able to replace Inside and Outside Plates but I cannot do it because I am asking to replace one part with the same part ie  Part 1 with Part 1 

I've tried to figure this out and haven't been able to do it. I looked and did research and experimented but no go.  I think I'm just a few clicks away from having this exercise all done, but it looks like it wants to give me (and you) a hard time right to the end.

Replace is a handy tool if you know how to use it. But it is not required.  There are only 3 parts, so just delet everything and re-insert to make thing easy

OK, I'll do it after I've given myself a good break ...until tomorrow. Thanks for getting back to me.

@john_mcclary - The Assembly is a success. ....my very first Assembly of my own Parts (except it was not without much needed help  ) It took me about 5 minutes to do it this morning. ....worked on it all day yesterday. The Replace Part thing threw me. ...no regrets.  It's all part of learning.

Cool


Yea, assemblies are not difficult at all. They are for placing parts and connecting them up. That's about it.

Part Studios are where all the modeling happens. Yet so many people are intimidated by assemblies.

Onshape makes the even easier than SW with thier mate connectors and group mate. Takes 1/3 of the effort.

Definatly worth learning.
