- [Instructor] I want to discuss the operations toolbar.
Operations are functions done to existing curves.
The first operation is what's called Corner.
You'll notice that, under the Corner,
I have Tangent Arc as well as Corner.
For this, I'm just going to simply select Corner.
And there's several ways you can go about making the Corner.
You'll notice under the sketch tools toolbar
that I have what's called Trim All Elements,
Trim First, No Trim to Any Elements,
Standard Lines Trim, etc.
I'm going to select my first curve.
Select my second curve.
And you'll notice that the arc is now active.
I'm just dragging along.
I'm not holding my mouse button down or anything.
This is just letting me know that I have an arc.
Where do I want to place the arc?
I can come in here.
I can enter in radius.
I can simply just select out in space
and create the arc that I want.
Now that I have my first arc, I'm going to go back
into my Corner function, create another arc
by using one of these other options.
Here, I'm going to create what's called a Standard Lines Trim.
First.
Second.
And done.
And you'll notice that it keeps the Corner,
but it trims those elements back to the Corner point,
giving you the arc.
I'm going to create another Corner.
Pick my two curves.
And this time, I'm going to go with a tool
that's called Construction Lines Trim.
Do exactly as you did before.
Select my location for my arc.
And you'll notice that I get these construction elements.
Construction element is simply a curve
that's, basically, a help line.
This allows me to keep my theoretical for that corner.
And you'll notice that this is
just a coincident line that's converted.
When I exit out of the sketcher,
this converted construction element will not be seen.
So, this is just something to help you create, build
within the context of the sketch.
All right.
I'm going to just trap all of these.
I'm going to delete.
And I'm going to throw a rectangle up there.
With my Corner function, when I select it,
I have, as you can see, various options.
I'm just going to go back to my Trim All Elements.
And for this, if I wanted to apply a Corner
to all four of these, all I have to do is
do a trap around those four points.
And you'll notice that, as I draw this,
you'll have four corners.
Basically, every Corner point that was selected in the trap
will have a Fillet or a Corner applied.
So, that's a nice, quick way to apply Fillets
if they're, all, going to be the same size.
We'll just go ahead and undo that.
Next, I want to talk a little bit about Chamfer.
Works basically the same except for, it puts in a flap
rather than a arc.
I can pick two curves, draw in my Chamfer.
And you'll notice that here,
I get an angle and a hypotenuse line.
I click on my Corner once again,
and I have several options here.
First Element Trim, so on and so forth.
I can go to Construction Line Trim.
I'm going to pick first line,
pick my second line.
You'll notice, as soon as I pick my second line,
I get some more additional options.
And you can see, by default, I have hypotenuse lines.
I can also change this to,
say, two lines versus second lines.
Or I can say length and angle.
It depends upon your needs, say two lines.
And you can see here, I have my construction lines
and my two lines coming off of my vertex.
Let me undo this.
I'm just using Control-Z on the keyboard.
I'm going to go all the way back.
Next, I want to talk a little bit about
some of the relimitations.
As you can see, these curves are, all, drawn out longer
than they need to be.
And I need to trim them back.
Now, this little function called Trim,
for a lot of people, it's a little tricky at first.
It's one of those operators that,
logically, when you think of trim, you're picking
what you want to trim away.
The way this works is this allows you
to pick two elements, curve, arc,
whatever those two elements are,
to trim them to each other.
In this case, you need to pick or select
on the curve, on the side that you want to keep.
If I want to trim away these two little ends,
I need to select on the other side
of that end for the trim.
So, if I pick here, you'll notice
that the curve is now extending based off
of where I selected up to the next element.
When I pick on this next element,
I need to pick on the side that I want
to keep or maintain or retain.
If I select on the other side, you'll see.
It trims away the other material.
This Trim function, like I said, can be a little tricky
because you're selecting on the side of the curve
that you want to keep.
I'll do that again on this other side over here.
Decide to keep.
Next I have, let me just go ahead and undo that...
Next I have Break.
Pretty straightforward.
It's like the element you want to break.
Where do you want to break it at?
I want to break it at this curve.
And what happens is you end up with two separate curves
that are coincident.
Here is Quick Trim.
I actually use this one quite a bit.
I'm going to pick on it.
And select the side of the curve that I want to get rid of.
This is probably something
that's a bit more familiar to most people.
So, with the Quick Trim function,
you're actually erasing away what you want to get rid of.
Now again, I've talked about this a few videos back,
but if you need to use this operator over and over again,
remember you can always double-click on it.
But double-clicking on it,
it keeps it active, any of the functions.
And now, I can just quickly select what I want to get rid of.
Just like that.
Next, for my relimitations, you'll see I have
what's called Closed Arc and compliment.
With Compliment, it gives you the opposite side of the arc.
With Closed, it takes an arc and makes it a full circle.
Pretty straightforward.
Those are our relimitations.
Next off of my operations, you'll see
several transformation functions.
The two that I want to talk about here
are Mirror and Symmetry.
And the reason I want to mention these right now is
because, with the mirror, when I pick these curves,
I'm just going to trap them.
And say, Mirror, you pick your (mumbles).
You'll notice that, not only does it mirror the geometry,
it makes a copy of the geometry.
I want to do a symmetry, symmetry across my plain.
You'll notice that it actually moves the curves
across your plain.
You want to be careful when you're dealing
with the Mirror or Symmetry.
If you want to move everything, it's symmetry.
And if you want to mirror everything,
basically, make a copy of it.
Again, it's Mirror.
It's a fairly consistent function inside of the sketcher
and on features outside of the sketcher,
as far as the naming goes.
So, if you see Mirror, it's going
to be a copy of the original data.
Symmetry's going to move the original data.
