- [Narrator] Earlier in this course we used the compare
documents tool to take a look at two different parts
and see what the changes were.
Now, I can use the exact same tool
and look at an assembly and see what has changed.
So, go ahead and click on compare
documents under the evaluate toolbar
and I'm going to go ahead
and open a couple different documents.
Now, I already have this 2.6 document open,
which is just a blank document,
so you can be in any document, it doesn't really matter.
But, what I'm going to go ahead
and compare are a couple of
the exercise files from earlier movies.
So, I'm going to go ahead and look in folder 2.2
and open that assembly
and click on open and I'm going to
compare that against the 2.3 assembly
and there they are.
So, those two assemblies happen
to be pretty much exactly the same.
However, four of the holes moved out a little bit
and one of them which we do correct later on in the design.
But, in this case here, we do have a small change
between the two documents
and if I can go ahead and look at the geometry
and then run the comparison.
It's going to say, "Hey,
"there's a bunch of parts here available
"and do you want to run the whole assembly simulation?"
Yes we would like to.
Go ahead and it might ask you
to start a couple new parts, that's okay.
It doesn't really matter,
it's just using that data to figure out what they are.
So, click on okay.
Alright, and it's saying we can't
do a face comparison only volume, which is fine to me.
And now we're basically seeing what's
being compared between the two parts.
As far as the parameters, you can see here what they are.
We're pretty much exactly the same.
You've got one tiny little kilobyte
or a couple kilobytes bigger, now that's about it.
And then over here, geometry result,
you can see here if I change from a volume comparison.
I can turn things on or off
and under blue, you can see here that
that tiny little sliver is that hole moving out,
that's what happened between those two parts.
I corrected an error in the alignment of that hole,
I think it was a 1.630, we then changed it to 1.625
to correct that and that's the interference we're seeing.
That's what's different between these two assemblies.
Obviously, be extremely hard to figure this out,
especially if you've got a bunch
of components in your assemblies
and you're trying to figure out what tiny little
changes happening between the two parts or two assemblies.
This tool's going to do it for us.
We can also click on some of the other changes here,
as far as what's happening.
Turn these things on, turn 'em off as needed.
Can also do a face comparison here.
Turn things on or off also.
Some of these things are easier to see
and some of them aren't, in this case here,
this one's kind of hard to see any face comparison changes.
But, the volume comparison really
does something pretty handy,
I like to be able to just turn this other stuff off here
and just kind of see what's happening.
That's what you can do in both these parts.
Show what's happening, see what kind of comparisons
you have at the end of the day.
Again, it's just a really great way
for the computer to do most of the work for you
and give you some good head's up information
about any type of changes
between your assemblies or your parts.
