- [Instructor] In this chapter, I'm gonna talk about
sketch options and settings.
So, in order for us to get into the sketch,
to work with the sketch, we need to create that sketch,
and the first step is to select
my Sketch in Task Environment icon.
Once I select the icon, my Create Sketch menu pops up.
You'll notice at the top, I have various types of sketches:
On Plane or On Path.
Now, they both basically do something similar.
They create a sketch that is gonna reside on a plane,
you still have to specify the same inputs
with where the sketch is, how it's oriented, and its origin.
The difference is that when you create one that's on a path,
it recognizes the path, so if you're doing
some future functions, sweeping that shape
along a guide string, it'll help recognize that path,
specifically for that sketch.
So, in this case, we're gonna use simply On Plane.
The first thing that the system asks for
is what plane is the sketch going to reside on.
Think of that plane as your sheet of paper.
So you're gonna tell the system where you're going to draw.
What's that sheet of paper?
Here, I'm just simply gonna select my x-y plane.
You'll notice that as I come over,
hover over the x-y plane on the screen,
the system tells me, "Hey, you're picking something.
"Is this what you want?"
So, once I pick, with my first mouse button,
it sets up my initial plane.
The next requirement for my sketch is my sketch orientation,
which is a vector.
This is going to determine, in this case,
what horizontal looks like on that plane,
so it's like your piece of paper.
Are you looking at it landscape mode?
Are you looking at it in portfolio mode?
Are you looking at it in portrait mode?
So, this is how you're orienting that sketch.
You may have a tooling direction that you need to orient to,
or you may have a specific orientation based off of the part
that it has to point in in order to align
the sketch correctly to the part.
Now, in this case, I'm just gonna simply
specify the x-axis of my coordinate system.
You'll notice as soon as I specify my x-axis,
I get my x-y-z coordinate system.
Remember I spoke about the work coordinate system
in a previous video?
Well, when I define my sketch,
I'm defining where that work coordinate system is going.
So, once I pick my horizontal axis,
my x of my sketch follows along.
My vertical is perpendicular on that plane,
and z is basically the direction of view.
You're looking down the z at that sketch plane.
The last option is sketch origin.
Basically, what is zero, zero, zero of that sketch?
If I look, I can specify a different origin,
or I can use my work part origin.
In this case, my work part origin is set
to absolute zero, zero, zero of the world
for the CAD system, and I'm just having the system
automatically use that.
If I have a point out in space that I want to use,
I can use that point out in space by specifying a point.
And this is very useful if you're designing something large
like an airplane or car, and you're using a data point
at the aft end, or the rear end, of the vehicle
that you're designing on, so you wanna basically
move your sketch to the location that you're working in.
So this is where this is very handy.
But for us, everything is just going to the default origin.
Once I specify the origin, I have all of the requirements
for my sketch; all I need to do is simply select OK.
As soon as I hit OK, I am now entered in
to my sketch application.
I know I'm in my sketch application,
because if I again look at the top,
it tells me what application I'm in.
I'm inside Sketch.
If I look at the tools that are available to me
and in my ribbon, I can see I have
my curve tools for sketch, I have my constraints,
it tells you right over here: Sketch inside of the sketcher,
as well as, you'll notice the ribbon changes.
I have a lot less tabs up there.
I don't have as much up there.
It's not necessary 'cause I'm in the sketch.
Once I'm in, by default, the first thing the system does
is it takes you to the profile tool,
and it asks you to draw something,
and this isn't necessary to use this tool to draw something.
If you want to, you can come in
and use one of the other tools.
In this case, I'm just gonna again draw a rectangle,
just for a quick reference.
So, you can go to Rectangle, draw the shape that you want,
and that is my sketch.
That's how I come in and position my sketch,
tell it where it's gonna be, and how it's oriented.
If I made a mistake on the orientation, I can always go back
and correct it by using the Reattach.
If I do select the Reattach button, you'll notice
it takes me right back to the original menu.
So, if I have to move the sketch,
change it to a different location, whatever that may be,
I hit the Reattach icon, and now I'm able to move it,
place it where I need that sketch moved to.
