create and edit a sketch.
00:06
After completing this video, you'll be able to create a sketch,
00:09
apply sketch dimension and constraint.
00:11
Use a center point rectangle and use trim
00:16
infusion 3 60 we want to get started with a new untitled document.
00:20
The first thing that I want to do is make sure that I
00:22
check my units under document settings by default it's going to be millimeters.
00:27
So I'm going to select this icon to the right and
00:29
I'm going to change my units two inch we'll say okay.
00:32
And now we're working with the inch unit system in the design work space
00:36
from here. We want to start by creating a sketch.
00:39
A sketch is going to be the foundation to most designs.
00:43
So in order to do that,
00:44
we can either select a plane that we want to sketch on
00:47
or we can select the create sketch icon inside of our toolbar.
00:51
Once we select create sketch,
00:53
it will automatically display any created planes for us in the origin
00:57
folder and we can select a plane that we want to use,
01:00
notice that the grid changes orientation when we hover over a different plane
01:05
For this example,
01:06
I'm going to select the xy plane and you notice
01:09
that we automatically go to a normal view from here.
01:13
We want to begin learning how to sketch and for that we
01:16
need to use the create menu under the sketch tools from here.
01:20
There are many different sketch elements and we'll be
01:22
covering them in various forms and different videos.
01:25
But for now let's focus on first creating a
01:27
circle and a rectangle first under the circle.
01:31
You'll notice that we have a lot of different options
01:34
if we simply just select circle,
01:36
all of our options are going to be displayed
01:38
in the sketch palette over to the right hand
01:40
side where we can make changes to which type
01:42
of circle we want to create for this example.
01:44
We'll be using center diameter circle,
01:47
we're going to snap to the origin by just
01:49
simply moving the cursor and then left clicking.
01:52
Then we're going to drag this out.
01:54
Notice that by default you can see a dimension is highlighted in the dimension box.
01:59
If we were to manually enter a value here such as five inches and hit enter.
02:03
We've now created a fully defined circle with a five inch diameter.
02:08
We can reposition this dimension if we need
02:10
to but the dimension itself is already applied
02:14
from here.
02:15
Let's go ahead and retry that center diameter circle at the origin
02:20
and this time I'm going to left click without placing the dimension.
02:22
Notice that I'm still on the circle tool
02:25
and the circle is actually a different color.
02:27
This means that it's under defined
02:29
from here.
02:30
What I wanna do is I want to add a dimension
02:32
manually and I can do this by using sketch dimension,
02:35
I'm going to select it and I can either apply another diameter value or I
02:39
can select the outside circle and put a distance between in this case .5".
02:46
Now we've created an inside and an outside circle.
02:49
I'm going to hit escape to get off the dimension tool.
02:52
What this allows us to do is create multiple profiles in a single sketch.
02:56
These profiles can be used for various commands such as extrude.
02:60
What I want to do is I want to create a few more elements.
03:03
But first let's finish this sketch
03:05
and let's just take a look at the result.
03:07
Once again we have two different profiles.
03:10
Both profiles can be used for various solid or surface features.
03:15
So from here we could select extrude,
03:18
select a profile of interest and begin pulling it up in three d.
03:21
In this case I'm going to manually enter a value of .25 and hit enter
03:26
as soon as we do that.
03:28
The sketch is now hidden and you can see at the very
03:31
bottom we have a sketch and a feature in our timeline.
03:34
But what if you wanted to make changes to that sketch?
03:37
Well we can simply double click on it in the timeline or we can right click and select
03:42
edit sketch in the timeline or we can right
03:44
click on it in the browser and select edit sketch
03:48
from here. I'm going to add additional sketch elements.
03:51
I'm going to select a two point rectangle
03:53
when I select a two point rectangle. Notice that we do have other options.
03:57
We've got a three point rectangle and a center rectangle.
04:00
Each of these options will allow us to decide how we want to
04:04
create our geometry for this example we use the center point rectangle.
04:08
I'm going to move the cursor until it snaps to the outside
04:11
edge and then I'm going to begin creating my rectangle from here.
04:16
I want to add some constraints because this isn't fully defined quite yet.
04:20
I'm going to use the equal constraint to make one
04:22
of the widths and one of the heights the same.
04:25
In this case we're creating a perfect square.
04:27
Next I'm going to use horizontal vertical.
04:30
I'll select its center point and the origin to
04:33
make sure that both of those are in line.
04:35
Next we're going to use sketch dimension and dimension the width.
04:40
In this case I'll use half inch so .5.
04:44
Now we can finish the sketch,
04:46
notice that the sketch is still hidden because it was consumed or hidden.
04:49
After the first extra was created.
04:51
We can use the eye icon next to the sketch to simply show it.
04:55
Now,
04:56
if we want to reuse this sketch we can simply
04:58
create another feature and reference it in this case extrude.
05:02
And you'll notice that we're having trouble selecting inside of our solid body.
05:06
We can hold down the left mouse button
05:08
and select the profile from our selection menu.
05:11
If we want to add additional selections,
05:13
we can hold down control and now we have all these elements selected.
05:17
Let's go ahead and rotate this around and begin
05:19
pulling this arrow so we can see what happens
05:22
as we drag this up in a way it's going to automatically treat it as an extrude cut.
05:27
If I were to drag it down, it's going to treat it as a join.
05:31
The boolean operators are automatically define whether the solid
05:34
bodies are overlapping or if they're simply touching.
05:37
If this solid body was completely separate, it would create a new body by default.
05:42
We can decide what the operation is by simply using
05:45
the drop down and deciding if we want to join.
05:48
Cut only maintain the intersection between the two.
05:52
We can create a new body or a new component.
05:55
In this case I want to use the cut option,
05:58
we're going to say okay, and now we can manually hide that sketch
06:02
While it isn't required that all of your
06:04
different profiles be contained in one single sketch.
06:07
Oftentimes it's helpful because you can reference the same geometry.
06:10
So let's edit sketch 1. 1 more time.
06:14
This time I'm going to use the line tool
06:15
and over on the right hand side, I'm going to begin drawing some line elements
06:20
and then I'm going to use the checkmark to say, okay,
06:23
now, once we've created a line,
06:25
we can hit escape to get off the line tool and we can take
06:27
the endpoints of this line and we can snap them to the outside circle.
06:31
But we also have other modified tools such as trim or extend that can be used.
06:36
If I select trim for example,
06:37
I can simply trim away the excess of that line
06:40
and I can trim away a portion of that circle.
06:43
You will note in some instances constraints or
06:46
dimensions will be removed during certain operations.
06:49
For example, this is no longer a complete circle.
06:52
So any constraints that we may have used or were applied to certain areas
06:56
could now be invalid
06:57
for this reason I'm going to use control Z to undo or we can use
07:02
the undo trim option up here because we
07:04
have the ability to select multiple profiles.
07:07
There isn't really a need for us to trim this unless we absolutely have to.
07:11
So I'm gonna go ahead and leave that profile.
07:14
It is important that we do add more dimensions to fully define our geometry and
07:18
for that we might want to use
07:20
something like construction geometry for this example.
07:23
What I'm going to do is select my line tool.
07:26
I'm going to go from the origin and I'm
07:28
gonna move around until I see that triangle icon.
07:32
The triangle icon means that we've reached the midpoint of this vertical line.
07:36
I'm going to hit escape,
07:38
select this horizontal line and place a horizontal constraint on it
07:43
from here.
07:43
I'm going to hit escape to get off my constraint tool,
07:46
select the line one more time and convert it to construction,
07:50
converting it to construction means that it's not going to be used to create
07:53
a profile but we can still have it in our sketch as a reference.
07:56
We can then use dimensions to fully define this.
08:00
For example, the length of this line 2.125,
08:05
The height of this line
08:10
And the angle of each of these lines
08:15
Another thing that we can do once we place the dimension is we can reference it.
08:19
For example,
08:20
in this case I'm going to select the 105 degree dimension and hit enter.
08:24
Now if I modify this 105 to let's say 1 10,
08:28
both of those are going to move this symmetric
08:31
relationship is created by linking the dimensions together.
08:35
There are other ways that we can do this such as creating mirrors of sketch entities.
08:38
But for right now let's just focus on some basic examples from here.
08:42
I'm going to finish the sketch.
08:44
Once again show sketch one,
08:46
create one more extrude and hold down the left mouse button to select that profile
08:52
in the extent type I'm going to select through all,
08:54
it's going to automatically create a cut and I'll say okay
08:58
then I can hide my sketch
08:59
and I can take a look at the results.
09:02
So this is a fairly simple example but this is the basis or foundation for modeling,
09:07
just about anything in fusion 360,
09:09
so make sure that you do practice and play
09:11
around with creating sketches and creating features from them.
09:15
We'll continue to explore these topics and once you're comfortable,
09:18
make sure that you do save your practice and then you can move on to the next step.
