- [Instructor] There are various
trimming options that we can use
and just to make sure you understand
what NX means by trim,
technically an area like this
is a trim.
When surfaces extend past
each other but also if
you have a gap.
That is also a trim.
Okay, so when they refer to
trim it means trim back
or trim forward.
There's a tool that I like
to use, it's called trim and extend.
And in this case,
I can use what's called
until selected, so if I have
a condition where I have a
gap like this,
I'm gonna pick the face or edge
and that's the key,
face or edge.
I have an edge that I
want extending out.
So I'm gonna pick that edge
and what do I want it
to go to?
This surface,
so I just pick that surface
and you'll notice that it
trims or in this case,
extend that surface up to
what I told it to go to.
So it forms a nice, tight
boundary edge along that surface.
So if I,
I actually want to form
a corner,
I can change this and
say make a corner.
Now you'll notice
I get these arrows and the one
that is extending out beyond
is trimmed back to actually
form a corner,
whereas the other one
was just a boundary edge
up along that surface.
So that trim and extend will
do just that,
it'll trim and extend,
you can either just simply
extend up to something
or if I say make corner,
in this case make a corner.
Now, this is again the arrows, right?
Arrows are very important,
you pay attention to them.
This is arrow side retain,
so this is telling you
what side you want to retain.
And if I say delete,
it's deleting the other side.
So I can switch that,
retain, delete.
Or I can just switch the arrow.
Whichever is easiest.
In some cases it's easier to
pick what you wanna get
rid of.
In some cases it's easier to
pick what you want
to keep.
Settings, this is how
the surface does an extension up.
So this is just showing you
it's a natural curvature extension.
There's several options here
depending upon the shape
that you're looking for,
if it's a large gap you need
bridged you may wanna play
around with, how it does
that extension up.
And then body output.
This is just telling you
it's gonna maintain the type
of surface based off of
the original.
And here I can say combine targeted tool.
With that turned on,
I select okay,
I have one feature
for my trim and extend.
The next tool I wanna
talk about is a tool called combine.
Now with combine,
it's similar to trim and extend
in that it's going to
trim a bunch of things to
each other,
but unlike trim and extend,
we go under more,
go to combine,
I can pick a bunch of
things to combine together.
Trim and extend is limited
to just the targeted tool.
Here, I can say alright
I wanna pick,
in this case I'm gonna pick this.
Right, this is that
previous trim and extend that
we used.
And then I'm just gonna come
in here and just pick
the rest of these elements
and you'll notice that
it basically is combining
all things, okay
There's also an option
for, I'm gonna go ahead and cancel
and I'm gonna undo the
trim and extend,
I'm gonna do an offset,
just to show you
a couple of really nice
options that it has.
Offset this down a bit.
There we go,
select okay.
Now with that,
I'll just go ahead
and do my trim and extend again.
Make my corner.
Again, make sure you pick
the edge, I could pick
the surface if they extend
beyond one another
but in this case I picked the edge.
And I wanna go up to here,
retain it, select okay.
Alright, so I have that edge
filled in.
I go back into combine.
Now, I pick this,
pick this,
and this and this,
and I'm basically picking everything
and you'll notice that
it does all of this
combining stuff based off of
the side that I pick on.
Well, if I come over here
and hit find volume,
it will automatically
switch sides for all the
bits that need to switch sides
in order to find a complete
closed off volume,
so with that,
I select okay
and there's my combined.
And in this case,
cause it is a totally
closed off volume,
it makes a solid so
takes all those surfaces,
combines them into one,
and in this case the volume is there,
it makes a solid.
