- [Instructor] Here you've see me bounce
in and out of the sketcher
quite a few times.
So this time I'm going to go ahead and turn to the sketch
and I want to talk about some of the options
that you have here,
and one of the most important toolbars
and is called sketch tools.
This is your basic interface
to within the sketcher upon how all of the other operators
that you're going to use, interact.
So, using the sketch tools toolbar
becomes very important
to anybody that really wants to be efficient and proficient
at sketching within CATIA v5.
So, what's the big deal about this toolbar?
When I come in and select any sort of function,
in this case rectangle.
What I want you to notice is that the toolbar changes.
It morphs.
It's asking me,
where does my first point go for the rectangle?
I can enter those coordinates in, hit enter,
or I can simply pick out in space.
By picking out in space,
you'll notice that once again,
the sketch tools toolbar has changed.
Following the cursor along,
and once I select,
it closes out
and it returns to its original icons
within the toolbar.
These original icons,
again are gateway
to how the sketch is going to interact
when you are creating.
You've seen me just create a rectangle.
Now you'll notice that there are some constraints
on that rectangle.
These horizontal and vertical constraints.
The reason why they appeared is
because I have a toggle turned on
and anything that's orange means that it's turned on
to reflect the creation of those constraints.
If I turn that geometrical constraint off,
and draw a rectangle,
you'll notice that there are no constraints.
So these lines are no longer considered constraint.
Whereas these lines are fixed to horizontal and vertical.
And that's why the sketch tools toolbar is important.
As you're drawing,
you want to make sure that
the options that you have set here reflect what you want.
So, once again,
if I turn on my geometric constraints,
create a rectangle,
you'll notice those constraints now come back on.
And this is important because as you draw something,
you may accidentally constrain to something next to it.
In this case you can see
I have a blue help line indicating
that it's going to constrain to that horizontal line
which is highlighted in orange.
So if I click and select there,
you'll notice that I get an extra constraint.
If I pick on that,
it's highlighted.
It's showing you that
it's constrained to an additional line.
If I had that turned off,
that wouldn't have happened,
but I'd also lose
the horizontal and vertical constraints of the rectangle.
So, as I'm drawing,
if I see these blue help lines
and highlighting orange line
from the previous set of curves,
and I don't want that constraint,
I can hold the shift key down,
and then now when I draw,
it's not going to constrain to anything externally,
but it will keep
the internal constraints to that sketched element.
So that shift key becomes important.
It works in conjunction with the sketch tools toolbar.
So that way you do get the internal constraints,
but not the external constraints
by selecting the shift key down.
And the same thing for dimensional constraints.
So if I come in here and draw another rectangle,
I know lots of rectangles.
I'm going to pick and if I come over here
and I say a width of 100,
and a height,
I just use the tab key over,
of 50, and hit enter,
you'll notice that as soon as I hit enter,
it puts those dimensional constraints in.
If I did not have that turned on,
then those constraints would not have been applied.
So, sketch tools,
very important that you understand
what's going on with them.
Again, if I pick another operator,
we'll say corner,
you'll see here
additional tools for the corner,
or if I pick once again chamfer.
Different tool,
different set of operators.
And the same is true for all of the other tools
that I can select draw with.
So pay attention.
Very important.
Critical you know what's going on
with the sketch tools toolbar.
