Hi Harry,
I think you might be best off copying the component and then using a Joint to place it. It is much more accurate than
Move/Copy then manually placing an As Built Joint. It also does not clutter up the timeline with moves.
I have just downloaded your model. Why do you have so many linked components? Is this a group effort? I can see
why you might want to split them into assemblies but there is no reason I can ascertain why you need to import
a link pin or a clamp. Especially since they all seem very similar.

There are WAY too many Move and Group components in the timeline. As a guide, if you need to group them together
then use Joints and they almost certainly should be a sub-assembly.
Nobody would EVER put this design on the market. It is so complicated that the assembly alone would cost a fortune
if it was done on an assembly line and if I had a choice between buying this and taking it home to assemble it, and
buying a much simpler one from the hardware store - I am going to the hardware store. The Monitor Mount has
ELEVEN Clamps. I am not sitting down to assemble that lot and I am certainly not going to trust my monitor that
may cost thousands of dollars to something with so many potential failure points.
Ergonomically it is way too complicated and there are so many pinch points that you would never get it past Health &
Safety. Surely this was not the design brief you were given? I found this mobile monitor stand in two minutes with
Google. This is much more feasable.

Some advice. Just because you can do something does not mean you should. If you actually designed all of these
linked components then you probably should have broken all of the links and gone with what you had and made
copies from the original. It would have made what I ended up with in my folder MUCH simpler. If you imported these
things from elsewhere then you should also have broken the links. I am quite happy to import from McMaster-Carr
but I don't need updates on things for what will obviously be a one off design.
You must also be using some super-computer to design this. All of these linked files and the complexity will be
slowing fusion down to snail's pace just re-calculating where you are moving and re-moving all this stuff.
Engineering and design is about making things as cheap and simple as possible to get the job done as safely as
possible. If you have never heard the term Keep it Simple S..... (insert appropriate S word here) then learn it and
start using it.
Another common saying is that if you build a BETTER mousetrap then the world will beat a path to your door. It isn't
a MORE COMPLICATED mousetrap.
Don't think I am being too harsh or picking on you please. I really am trying to help. I would strongly recommend
getting on the AutoDesk YouTube channel and looking at how some of those guys go about designing. I would
also read a few books on design and try to get an idea on different ways of going about it. It is hard to tell but it seems
that you have taken the advice of using off the shelf parts to keep costs down, but there is a point where a well
designed custom part is much cheaper than a collection of off the shelf parts.
Cheers
