- [Instructor] Now I wanna talk about selection intent.
Selection intent is a very powerful tool
and pretty much everything that you do,
you have to consider how you select because the way
NX is set up is it remembers those selections.
So as you're performing a function,
as you're doing something you wanna make sure
that the selection intent is set up correctly.
And I will be reiterating this when I show you
some of the additional tools that we're gonna get into.
But I wanna give you a broad understanding
of what selection intent is up front.
Now when we look at the top, this top toolbar here,
you'll see I have no selection filter, entire assemblies,
several icons and then point selectors.
These are all meant to help you in selecting
the geometry that you want.
So in this case I have basically no filters set up.
So if I come over and hover over the top of something
you'll see it wants to pick a face.
I could potentially get it in edge.
Now you'll notice that if I hover over the top of something
for long I get what's called a quick pick selector.
If I pick you'll see a list of all of the things
contained within the selection ball there.
I can filter this out with features,
I can filter this out with body objects.
You can see I have different objects here,
and just close it out.
So if I wanna be very specific about something
I can come over here and say you know what,
I wanna pick nothing but faces for example,
or maybe I wanna pick nothing but solid bodies or sketches.
So in this case if I say solid bodies
when I pick, you'll see that all I have is one solid body.
It's not picking faces, it's not picking edges.
You'll also note that with solid body set up here,
some of the other selection intent disappear
'cause these are meant to help you pick center points
off of edges, points on an edge or points on face.
So because I have this set to solid body,
these are no longer available.
If I come over here and do a deselect all
or do a reset filter,
you'll notice that everything is deselected,
everything is reset to the original
and you have all of your selection intent
available once again.
If I have this set to let's say solid body again,
you'll notice out in the screen I can only pick the solid,
but if I come over to my model navigator for instance
I can still pick those elements here,
they're not filtered out.
Alright so I'm gonna reset that.
Some of the other selection options that I have,
I'm just gonna escape on the keyboard to deselect everything
couple times, some of the other options that I have
for selection intent are things like trap.
So if I click and drag holding the first mouse button down,
you'll notice I just trapped in all of those faces,
edges and such.
I'm going to deselect all,
so if I change this and say edge and do a trap,
you'll notice now I'm just getting edges,
not the actual faces.
Okay let's reset, deselect.
You have different type of traps, lasso, circle.
Now as far as additional parts of selection intent
that you should be made aware of is they do change,
your selection types change based off of
the feature that you're creating.
So for example, if I come in and create an extrude
you'll notice selection intent changed.
You'll see I have connected curves,
all of the point selection functionality is deactivated
'cause you can't extrude a point.
But you have all of these methods of picking the section
or the shape that you're going to extrude.
Cancel that out.
If I go into let's say edge blend,
well this is technically going to apply to edges.
So you'll notice here again, the point selectors
basically gone and I come in, it's gonna pick tangent curves
and you'll notice that some of the terminology
is similar between the features as well.
So if I use let's say tangent curves
I could come in, you'll notice it's not picking any faces.
If I come over here, go up to tangent curves
and change this to say face edges,
now you'll notice it's not gonna pick an edge,
it's gonna actually pick a face.
So the intent is going to be remembered
inside of your selection intent.
Now if you did pick things, let me come over here,
go back to tangent curves, let's say you're picking things
and you realized as you're picking edges
you've accidentally picked something,
just hold the shift key down to deselect whatever it is
that you've accidentally selected.
Okay so, that allows you to instead of canceling out
or escaping out of whatever it is you've picked,
you can now be very specific about what you're deselecting.
And again that's the shift key on the keyboard.
Also, as far as selection and selection intent
I should mention at the top of all of our menus
we also have a reset, and this just basically resets
the selection for each one of those menus or tools
that you have open at that point.
And it's just for that moment,
just resets what you have selected.
Other parts of selection intent
again, you have filters so you have general filters.
If I click on general filters,
you notice you can do detailed filtering,
you can filter by colors.
You can also do all sorts of really finite,
detailed filtering depending on the type of elements
that you have in the file.
If you have curves, you know you have curve features,
you have datums, edges, whatever you have in that file
so you can get really specific about display attributes
with your selection and selection intent.
Now right now you'll see datums is currently picked.
And if I try to come out here and pick anything
it's not gonna allow me to pick anything
'cause the selection intent.
Often times when you are using your selection intent
and especially when you're new to the system,
you know it feels like often times it's broken,
I can't pick anything, why can't I pick anything?
It's because your selection intent is set
to something that does not allow you to pick those things.
So make sure that if you see the reset filter icon,
this is a big tell.
If you see something in here, this is another big tell.
Just come over here, hit that,
you'll notice no selection filter,
that icon is no longer highlighted
so at this point everything is back to defaults
and you should be able to pick pretty much anything.
As far as the detailed filtering,
as far as some of the other objects,
I don't use that a whole lot.
It's a great tool, kinda rare.
Another thing you should be made aware of,
often times maybe you wanna pick a range of things,
you pick in the part navigator here
and if I wanna pick a range I can hold the shift key
and pick that range.
So you can pick everything between the two elements
that you've selected.
If I wanna pick multiple elements that are not in a range,
I can hold the shift key,
or I apologize the control key down
and pick multiple elements.
It's not common that you use the control key,
but there are instances where do you have to
use the control key in order to multi-select your elements.
So it's fairly rare, it does happen
but that's basically how you do it with the control key.
It's similar to an Excel spreadsheet,
you pick a range, you hit shift key,
you wanna pick onesie, twosie,
then you hold the control key down.
But that's basically it,
that's how you pick things, your selection intent.
Again, just make sure that everything that you do
if you're having a hard time picking,
just check this little bar up at the top,
very, very important.
