How to create and edit a basic sketch.
00:05
After completing this video,
00:06
you'll be able to
00:08
create a sketch,
00:09
edit a sketch,
00:10
create a sketch line,
00:11
circle,
00:12
and rectangle.
00:15
In Fusion,
00:15
we're going to begin with a new untitled document.
00:18
Inside of our untitled document,
00:20
we want to begin by creating a new sketch.
00:23
Let's quickly take a look at the origin folder and make
00:26
sure that it's visible by clicking on the eye icon.
00:29
By default infusion,
00:31
we automatically have an XZ plane,
00:33
a YZ plane,
00:34
as well as an XY plane.
00:36
These default planes,
00:38
as well as the origin location and axes are all the
00:41
central focus of where we need to start our design.
00:44
It's always a good idea to start your new designs at one of these planes.
00:49
There are a couple ways that we can start a new sketch.
00:51
We can pick a plane from the origin folder,
00:54
right click,
00:55
and select Create a new sketch.
00:57
We can select a plane on the screen,
00:58
right click,
00:59
and create a new sketch.
01:01
We can also select Create sketch,
01:04
which will allow us to select a plane.
01:06
And if the origin folder is not visible and we select create sketch,
01:10
it'll automatically make it visible temporarily so we can make our selection.
01:15
There are a few other ways that we can start a sketch,
01:18
for example,
01:19
using the shortcut key to start a line.
01:21
L on the keyboard.
01:23
This will automatically invoke the create sketch command,
01:25
and as soon as we select a plane,
01:27
we'll be using the line tool automatically.
01:30
For the most part,
01:31
we generally start a sketch by clicking create sketch and then we pick our plane.
01:36
This case we'll pick the XY plane.
01:39
Now we're looking at our sketch in an orthographic view with a normal orientation.
01:44
We can reset the normal orientation by using look
01:47
at if we happen to rotate our view around.
01:50
Simply select look at inside of our sketch palette
01:53
or click the Lookout button at the bottom center of your screen.
01:56
The sketch palette contains general information that we can use during sketching.
02:01
When we invoke a sketch tool such as rectangle,
02:04
more information will be presented at the top
02:06
if there are options for that specific tool.
02:08
For example,
02:09
using a center point rectangle can be clicked on here in the sketch palette.
02:14
We can also find it by expanding our Create menu
02:16
and navigating over to the rectangle
02:18
section and selecting Create center rectangle.
02:21
From here,
02:22
creating a new sketch entity is simply about clicking
02:26
and then clicking again.
02:27
In some cases,
02:28
you'll find that your sketch entities will
02:30
have dimensions highlighted on the screen.
02:33
If we want to apply those dimensions at the time of creation,
02:36
we can,
02:37
but we'll be talking about that a little bit later.
02:39
So for our purposes,
02:40
simply left click to accept the creation.
02:43
We can continue to use this tool as denoted by
02:46
the icon at the bottom right of our cursor,
02:48
or we can hit escape or right click and select cancel or OK to get off the tool.
02:54
Once the tool is inactive,
02:56
it's important that we note a few things.
02:58
On the screen,
02:59
we are able to move around this rectangle because it's underdefined.
03:03
Underdefined means fusion doesn't have enough information
03:06
to positively define its size and location.
03:10
The center point of this rectangle is defined at the origin.
03:13
It has a couple of these dashed orange construction lines,
03:16
but the rest of the sketch entities are blue.
03:18
This means they're underdefined.
03:21
Once we're done with the creation of our sketch,
03:23
and we click finish sketch,
03:26
we'll exit the sketch environment and the sketch will
03:28
be listed in the timeline at the bottom,
03:30
as well as in a sketches folder.
03:32
The small pencil icon in the bottom right tells us that our sketch is underdefined.
03:37
We are able to grab it and move it on the screen and make adjustments,
03:41
and this is one reason why we always want to have fully defined sketches.
03:45
We want to use our dimensions and constraints to
03:47
make sure that our sketches are fully defined.
03:50
We're going to get into that in a future video,
03:52
but for now,
03:53
let's double click on our sketch icon in the timeline
03:55
to go back into edit mode.
03:57
From here,
03:58
let's take a look at using a couple of other sketch tools.
04:01
We also have the line tool.
04:03
As we start the line tool,
04:05
we can continue to make additional lines by simply left clicking at each point.
04:10
If we go back to the last endpoint and hold down the left mouse button,
04:13
we'll transition this into a tangent arc.
04:16
Once we let go,
04:17
the arc will be created and we can continue on with the line tool.
04:21
Once we're done,
04:21
we can use the green check mark,
04:23
which will leave the line tool active,
04:25
or we can hit escape or again right click and use OK or cancel.
04:30
We have other sketch entities that we can create,
04:32
things like circles.
04:34
Once again,
04:35
there are multiple options.
04:36
With the circle tool,
04:37
we generally will create a center diameter circle,
04:40
but we can also define circles by 2 or 3 points
04:43
or by things like making tangent curves.
04:45
Let's explore a couple of these options.
04:48
First,
04:49
if we create a center diameter circle,
04:50
we simply need to click to place the first point
04:53
and then click to place the radius or diameter.
04:56
Then if we go to our circle tool and say use a 3 tangent circle option,
05:01
we need to select 3 references
05:03
and a circle will be created that's tangent to those 3 references.
05:07
Let's go ahead and hit escape to get off of our circle tool.
05:10
As we change the size of our sketch,
05:13
we can see that the circle itself is going to update and change
05:16
because it's using the constraint system to drive some of its values.
05:20
Creating sketches can be a complex process,
05:23
but it's important that we learn the fundamentals at this stage.
05:27
Let's go ahead and hide sketch one and let's practice just a little bit more.
05:32
We're gonna create a new sketch,
05:33
this time we're gonna select the front plane.
05:36
We're gonna start using a center diameter circle.
05:39
And with the blue value highlighted,
05:41
we're gonna manually enter 100 and hit enter.
05:44
This is now a fully defined sketch.
05:47
It has all the information it needs to define its position and its size.
05:51
The 100 millimeter diameter
05:53
turned the rest of that sketch circle to a black line.
05:57
Once we finish our sketch,
05:58
we can also see inside of our sketches folder that we have a red lock icon,
06:02
which represents a fully defined sketch.
06:05
The small pencil icon tells us that sketch one is underdefined.
06:10
Let's go ahead and hide this and try one more time.
06:14
Once again,
06:15
we'll create a sketch on the front plane.
06:17
We're going to expand our sketch tools
06:19
and note that some of them do have shortcut keys.
06:22
L for line,
06:24
R for rectangle,
06:25
and C for circle.
06:28
We can also explore other tools like arc tools,
06:30
polygons,
06:31
or ellipses.
06:33
For this example,
06:33
let's go into the slot tool.
06:36
We're going to use the center point slot tool,
06:38
which allows us to select the center point,
06:40
in this case the origin,
06:42
drag out a specified distance,
06:44
and then drag out the radius or diameter value of the slot.
06:48
You'll note automatically constraints are added for
06:50
tangency around the outside of our slot.
06:53
This means that the arcs on the edges are tangent to the lines at the top and bottom.
06:58
If we had escaped to get off of our slot tool,
07:01
because we didn't add any dimensions,
07:03
this is still underdefined and allows us to move it around.
07:06
It has a center construction line that is driving the overall width of our slot.
07:11
This can be modified,
07:12
a dimension can be added,
07:14
or this slot can be removed and changed.
07:17
The center line has a constraint that keeps it horizontal.
07:21
This means that the rest of the slot will
07:22
always remain horizontal unless this constraint is removed.
07:26
Make sure that you do explore the creation of new sketches
07:30
and understand some of the sketch entities that you have available.
07:33
Make sure that you focus your time on learning
07:35
the basics of creating each of these items,
07:37
such as lines,
07:38
circles,
07:39
and rectangles,
07:40
as they'll be the foundation for most of your designs.
07:43
Once you're done,
07:44
feel free to save this document,
07:45
but we won't be using it again,
07:47
so we can just finish up and move on to the next step.
