component1 vs. component2 adding joint

[Anonymous]

I was following a tutorial off of lynda.com and I got to the point where we were adding joints. I was active on the top level of my project and all my objects were components. When I went to add joints, I was unable to select any of my components as Component1, but they all became available for selection if clicked 'select' for component2...I am very confused as to why there is a difference between component1 and component2...I did not save the file because it was just an exercise and I do not want to clutter up my cloud since I am of the impression that you can only archive, but never delete project files.

" a tutorial off of lynda.com" is not really a description of what you're doing. It would be great if you could export and share your project so that we could check it. Sometimes a screncast might be enough, too. But mostly a look at the design is very useful.

@Anonymous: Thanks for your PM. I think it's so valuable that I like to share it:

 I'm just asking myself if this ignore button is only for PMs. What a wonderful day.

@Anonymous,

There is some difference between Component1 and Component2 in the Joint command.  When you start the command, any components which are grounded are not selectable for Component1.  This is primarily done to prevent you from creating joints which will fail (for instance selecting two grounded components).  Once a non-grounded component is selected, you can then select grounded components for Component2.

Yes, technically, the joint would still succeed if you picked the grounded one first, so this is a bit confusing, I agree.

it is very possible that all my components were grounded!

If CAD was easy we could answer posts such as yours without needing to look at your design.

However CAD is a fairly abstract field and an abstraction is apparently what you are having a problem with.

As such asking for data is a very common thing, not only on this forum.

If you want help then provide data, the design in this case. This is a forum where users help users. Expecting other users that provide help here voluntarily to recreate a model based a tutorial that might not even know is rather rude, inconsiderate and disrespectful.

this is also where autodesk employees respond...seriously, i dont expect anything from anyone on here...i said i didnt provide a file because i didnt want to save the file since it was an exercise...there is not file for me to fix..thats how little i cared about the situation...obviously i made that clear in my original post...so if it is not worth the time to respond, then why respond about how i should have made it easier for anyone to invest their time into something that means so little to me...not everything in this world is worth saving...
