- [Instructor] So while you're creating surfaces,
or sheet bodies,
there are a lot of different settings
that you have to consider there.
And typically once you get those settings all set up,
you don't really have to worry about them.
But, I wanna make sure you understand
what those settings are, and where they're at,
because there is a couple of different areas
you can go to for those settings.
Now, the first one is located under File,
Utilities, Customer Defaults.
Customer defaults basically are
almost all of the overarching defaults
for anything that you going to do in NX.
And here, we have freeform modeling,
and you'll also see freeform parameters.
The term freeform basically refers to
the various modules or tools in NX for surfacing.
So anytime you see the word freeform, think surface.
So, under freeform modeling you'll see a curve fit method,
you have cubic, quintic, advanced.
This is basically what you're doing with curves,
the defaults for the amount of math the curve has.
Construction results, if it can be planar, it'll be a plane,
versus it being a B-surface,
you'll end up with very different results.
Preferentially we use plane,
because it's a much simpler type surface.
And so just scroll down a little bit,
you can see we have other options as far as style,
you have linear, logarithmic.
This is just, again, an overarching setting
for some of the analysis tools and how things are viewed,
as well as default actions when you
double-click on a spline,
or default actions when you extend out surfaces.
And you'll also notice we have
an associative freeform editing.
So, you wanna make sure you have these things set correctly.
For me, I use the studio spline tool
instead of the X form tool
for default actions on splines.
There's a little difference in how they act
and interact and such.
If I go over to color and font,
this is just, when you're doing an analysis,
you'll see the pole color,
you'll see the polyline colors, those things,
and you can get all that set up.
You may want something different than the defaults.
As you can see, sometimes if you have a lot of blues
it may be a little difficult to see your analysis,
your display lines, or your grid lines.
So you can come in here and change those,
make them a bit more obvious.
If I go over to the freeform feature parameters,
you'll see there isn't much here,
and the default is cubic, and that's
for a tool called Swoop.
So you really don't have much to worry about
in this general setting area,
so just leave this alone.
Just wanted to point out that it was there.
The next place that we have some settings are under menu.
And I'm gonna go down to preferences, under modeling.
Now, some of these are going to be
redundant from the utilities.
If I look under general, here you can see
I have some curve optimization.
If I have freeform set here, you notice I have
cubic, quintic, advanced once again
for the curve fit method.
And this is going to be basically for
the existing part file that you're working on,
so you may wanna change something.
Maybe you're doing something that has a lot more math,
and you need a lot more additional, I guess, math,
or higher polynomial curves.
That'll default as they're being built,
then you can go and change the settings here.
Same thing, the plane, the B-surface.
Associated freeform editing is turned on.
And again, you can see how I have my actions
for splines and extension methods set up.
Another place, just to make sure
that you have it set correctly, is under edit.
So, when you come under edit, you wanna make sure
you have edit with rollback, edit with rollback.
The edit for the sketch action, task environment.
For surfacing I, again, highly recommend
that you use that task environment.
So, that's basically most of the settings
that you're gonna have to deal with
when it comes to surfacing.
If I look under update as well,
you'll see some dynamic mode updates,
and incremental level updates, and how deep updates go,
and this is for when you are doing
some serious freeform modeling, and NURBS manipulation.
I just wanna mention it here,
just give you an idea of really
what the dynamic update is for.
But you'll see as I go through the course,
when I start manipulating curves and things of that nature,
the nature of how dynamic the curves are.
So, you have some control over that as well.
And it's not obvious that it's located under update,
but that's where those settings are
for those types of updates.
