- [Instructor] Now I wanna build a new assembly for you.
So, I'm gonna start off by going into New,
and you'll notice under my Templates
I also have Assembly,
just as a note.
A Model,
and an Assembly,
and a Shape Studio,
all of these have the same
basic file extension, dot PRT.
The only difference between the Model and the Assembly
is there may be some naming difference on layers,
there may be some differences to colors
or specific attributes that your company
has chosen to have as part of the assembly,
but other than that,
the data, the files,
everything, are the same.
There's no appreciable difference.
I know a lot of other CAD systems use
dot extension with an assembly name.
In NX there's none of that.
It's strictly a dot PRT.
So, if you accidentally built,
or used a model I should say,
to build an assembly,
it's not gonna really matter,
except for maybe some naming conventions
internal to the file like the layers.
But that's really about it.
Now,
when I select on Assembly,
again I want to make sure I'm saving
the assembly into the correct folder,
and I need to give it a name.
So, I'll just type in Valve Assembly.
Select Okay.
And once I come in,
you'll see here,
I can begin adding components.
If I have components that are already open
somewhere in the background,
or in memory,
it'll list them here.
If I don't already have them open,
I can go and say Open,
and it'll take me to my Part Name window,
basically my menu to go and look for the parts.
Here, I can just simply grab one component,
you can see there's my housing,
there's my valve cover,
and so on.
I can use my Control key to pick several components,
or if you wanna pick 'em all,
just pick the top one,
hold the Shift key down,
and pick them all and bring them in all at once.
This go 'round,
I'm just gonna simply bring in a housing,
and I'm gonna select Okay.
And as I bring it in,
there's various options here that I need to consider.
How many of these do I want?
Well I only want one of these.
Where is this going to go?
Component Anchor is the Absolute of the file.
Assembly Location,
where is it gonna go in the assembly.
So, this is asking me from the part,
into the assembly.
Where do I want this to go?
I'm just gonna put it in at the Absolute of the part,
and then,
this just allows me to cycle orientation,
so if I want to,
I can reset the Snap Position,
I can rotate the component 90 degrees,
here in the window.
So this just allows you to quickly
snap things into place.
And then for the placement,
you'll notice here I have Move or Constrain.
In this case I'm just gonna place it.
I don't wanna constrain anything.
If I do Constrain it,
I can apply a fix,
but I'll come back and talk about constraints.
And then if I look under Settings,
come down here,
this is a Component Name.
This is what,
as a description in the assembly,
this is gonna be called by default,
the Part File name.
You can give this a different name if you want.
Reference Sets.
There's a Reference Set that is
based off of your layers.
We talked about that in a previous video.
It's important you have your Data Set
organized so the solid's on that Layer One.
And for now I'll just leave it on Entire Part.
And Layer Option,
just leave everything at Original.
And when I hit Okay,
it's gonna ask me a question.
You just added the first component to the assembly.
Do you want to create a Fix constraint?
If I hit Yes,
what it's going to do for me,
let me come up to my Assembly Navigator.
You'll notice that there's my Fix constraint.
It automatically put that in for me.
Basically it's asking you as a courtesy.
Chances are this is the first component.
It's gonna be a Fix component.
You're gonna assemble things to that.
If you don't want that Fix constraint,
you accidentally hit Yes,
you can just delete it from the window here,
or you can go back and delete it,
you can hit No on the insertion
of that component into the assembly.
So in this case I do want it.
Now you'll note that I have
all of this extra data in here,
right,
so I need to clean this data up.
So if I want to clean this data up,
this is a very, very, very important
thing to remember for cleaning the data up.
The layers that we're looking at right now,
they're for the assembly.
If I want to clean the layers up
of this part as we have open,
I need to have that part open all by itself.
So, I go to this part.
I'm just gonna right mouse click on it.
I'm gonna say Open in Window.
It's gonna put it in it's own separate window.
And here,
if I look at my Part Navigator,
here are my sketches and all this other stuff.
Show all that.
So I'm just gonna go through,
quickly organize this up.
Remember,
I'm organizing the data with
the file open in it's own separate window.
So for this,
I'll just go back into View,
I'm gonna say Move to Layer.
I wanna take the solid,
put that on Layer One,
and go to Layer Settings,
make Layer One the Work Layer,
turn off my display for all the other parts.
And then now,
when I go back into my assembly,
and I look at my assembly,
I wanna use what's called Model Reference Set.
So I just go over to the component,
right mouse click,
Replace Reference Set,
and Model.
I did that a few times so you can see
exactly where it's at.
And because I moved everything off of Layer One in the part,
and put just the solid on Layer One in the part,
when I come into the assembly,
now when I look at just the Model Reference Set,
just like that,
everything gets cleaned up.
I won't see all of that extra data.
I don't have to Hide/Show anything.
That Model Reference Set is that viewing tool,
or that filter of what's on Layer One,
in this case,
into that assembly.
And again,
all that's done automatically behind the scenes.
So, at this point,
I'm just gonna go back into my Assemblies tab,
and I'm just gonna Add Additional Components.
I added the first one in.
Now when I go into Add,
I want to bring in these other components,
so I can use these that are already currently open,
like the cover for example.
And then I have the stem as well.
So you can see these are out in position.
If I scroll down to the bottom,
right now our Reference Set is set to Original.
If I turn that to Model,
'cause I already have those files cleaned up,
the visualization cleans up.
I get rid of all of that extraneous data.
The visualization filter of that Model Reference Set
is now what I'm looking at,
strictly here in that assembly.
I'm gonna select Apply.
Just put them there in position.
And I'm just gonna go back now to Open.
So I already have the cover,
and I already have the stem,
so I want that plate,
and I want that arm.
Hold the Control key down,
pick the two of those,
select Okay,
make sure your Reference Set is set correctly.
Again you can go back and modify that.
Now that I have all the components in that I want,
I simply select Okay.
And again, this,
you know the Reference Sets,
very important,
very important.
Again if I switch it over to the entire part,
you can see all the data within.
I can switch it back over again.
Just go back to Model;
it's like a little switch.
Again, if you forget to move that data around,
then it's real easy,
just open up that part in a separate window,
and make the changes.
