sketch splints and slots.
00:06
After completing this video, you'll be able to create a sketch slot,
00:10
a spline and iconic
00:13
Infusion 3 60, let's get started with a new untitled document.
00:17
We want to begin by creating a new sketch and you can pick any sketch plane.
00:22
We want to take a look at some of the additional
00:24
sketch entities that can be created in fusion 3 60.
00:27
We've already taken a look at using the line, the rectangle as well as the circle.
00:31
But there are many more that we want to make sure we're familiar with.
00:34
First let's take a look at slots.
00:36
There are five different types of slots which
00:39
essentially give two different types of slot geometry.
00:42
We've got horizontal vertical slots and then we've got our slots.
00:46
We're going to be using the center point slot, which is the third option in the list.
00:52
From here.
00:53
We want to select the origin and then begin dragging out the center line of our slot.
00:58
This can be at any angle you wish, for example,
01:00
we can put this at a 45° angle once we pick the
01:04
end point will then begin creating the radius of the slot.
01:09
If we don't enter any dimension values,
01:11
you can see that it's under to find if I had escaped to get off my slot tool,
01:16
I can begin moving this around and resizing it as needed.
01:19
I'm going to select the construction center line and place a horizontal constraint
01:23
and then I'm going to use my dimensions to dimension the radius value.
01:28
In this case we're going to use 25 mm and the overall length. Center to center of 150.
01:35
So we have a fully defined slot.
01:38
If we go back up to create slot and we take a look at our center point arc slot,
01:43
we first need to select the center point,
01:45
the start point and the endpoint of our slot
01:48
and then we can determine the radius value.
01:51
Once again, if we don't enter any dimensions, this is going to be under defined.
01:55
I'm gonna hit escape and note that we can still move this around.
01:59
We can use constraints and dimensions to fully define it.
02:02
For example,
02:03
control selecting the two endpoints and making
02:05
sure that they're horizontal with each other
02:07
Using dimensions to give it a radius value. In this case 150.
02:12
And we can give it a radius value of 15
02:17
and then we can determine how to dimension the ark itself.
02:20
And in most cases you'll want to use construction line geometry.
02:24
In this case we're going to go from the center point to here and I'll hit escape.
02:29
We'll turn this into a construction line using our line type option.
02:33
And then we'll use dimension to go from that
02:36
line to our horizontal and give it an angle
02:40
because we said the endpoints were horizontal. This will fully define our slot.
02:45
A slot geometry is very helpful for mechanical designs,
02:49
but often times we need to use more advanced
02:51
sketch entities if we're creating more organic type shapes.
02:54
So let's finish this sketch.
02:57
Go to our sketches folder and hide it
02:60
and let's start a new sketch on the top plane
03:03
next. When we take a look at create, we have splints,
03:07
connick curves and ellipses first. Let's take a look at splints.
03:11
There are two main types of splints that we can create.
03:14
A fit point spline and a control point. Spline.
03:17
The fifth point spline is used to create
03:20
spline with control points located on our spline.
03:23
Let's go ahead and just create a spline using
03:26
three clicks and then click the green check mark,
03:29
hit escape to get off your spline tool.
03:32
Once you see the spline on the screen,
03:34
you'll notice that each point we clicked has a green handle associated with it.
03:39
This is going to control the tangent C direction as
03:42
well as the weight or influence of that tangent.
03:45
C points can be added or removed by selecting them and deleting them to remove it.
03:50
Or by selecting the spline, right clicking and using insert spline foot point,
03:57
we'll escape to get off the insert tool and we can manipulate the spline points.
04:02
It's important to note that once you activate the handle,
04:05
it's going to cause an influence in the spline itself.
04:09
When you select the spline,
04:10
you can toggle on curvature comb analysis to get a good idea as
04:14
to what the spline is doing in terms of its change in radius.
04:19
You can see here that we have an inflection point that goes from concave to convex.
04:24
I'm gonna hit cancel. So I'm not showing the spline curvature combs.
04:28
Next I want to go to create spline and use the control point spline once again,
04:34
let's go ahead and select three points and then hit the green checkmark.
04:39
It escaped to get off our spline tool and notice
04:41
that this is defined in a much different fashion.
04:44
This type of splint is controlled by an external cage.
04:48
The cage is going to define the direction of tangent C.
04:52
As well as the influence or weight that it has.
04:55
Typically these control point type of splints are going
04:58
to be much easier to control smooth geometry,
05:02
fit points.
05:02
Prinz take a little bit more finesse but they often times allow you to get closer to
05:07
a shape you're trying to match if you're using a canvas or an image in the background.
05:13
It is important to note that spline curvature is going to have
05:17
a direct influence on any features that are used after the fact.
05:21
So you need to make sure that your spline or curve geometry is nice
05:25
and clean and you don't notice issues like changes in the direction of curvature.
05:30
If we leave the curvature comes on and we begin to manipulate the spline.
05:34
It's going to cause issues in the curvature because of this internal handle.
05:40
So it's always my recommendation to create splints with the fewest number of
05:45
spline control points as possible and that's true for a fit point spline.
05:49
However,
05:50
when we have a control point spline having additional control points
05:54
on here often times gives us a much nicer transition,
05:59
we're going to hit escape to get off my insert
06:00
tool and you can see by manipulating these points,
06:04
we can get a nice smooth result
06:06
once again we can display the curvature combs and
06:09
we have a nice smooth transition in curvature.
06:13
So it's very important that you play around
06:15
with splints and understand their implications in terms of
06:18
how they are created and what the end result in the geometry is going to be.
06:22
Let's go ahead and hide that sketch and let's create one more.
06:26
Again, there are many different sketch elements, things like polygons,
06:29
but we want to focus on ellipses and connick curves.
06:33
Now,
06:33
iconic curves are an interesting type of curve where
06:37
we're looking at a plane slicing through a circular cone
06:41
to create iconic curve. We want to define three points
06:45
and then we have a row value as the row value is closer to one.
06:50
We're creating much closer to a cone shape as the
06:54
cone or the row value is closer to zero.
06:57
What we're doing is we're slicing through the bottom
06:60
of the cone as this value goes up,
07:03
we're increasing the angle that we're going through a cone.
07:07
The cone radius value is determined by the distance of the end points
07:11
and the row value is determined by moving this area
07:14
up and down or manually entering the value here.
07:17
It is important to note that you can only go up 2.99 and down 2.01.
07:23
You cannot go to one or zero. In terms of the extent of the row value.
07:29
We're gonna go ahead and right click and select OK to
07:31
accept the comic curve and if I double click on it,
07:34
the row value is shown and we can make manipulations once more.
07:40
Next let's go to create and take a look at the ellipse.
07:43
The ellipse is relatively simple to create and can offer a very nice curve result.
07:49
We're going to select a center point horizontal point
07:52
and a vertical point to define our ellipse.
07:55
We're gonna escape to get off the ellipse tool and note that we can
07:58
still manipulate this and we can use our dimension values to drive it shape.
08:03
For example, 100 millimeters tall
08:06
And 275 mm wide.
08:09
We do have a horizontal constraint automatically applied on
08:13
one of the reference lines and then I can escape
08:16
to get off my dimension tool and I can move it to my origin to fully define it.
08:20
So these are a couple of different types of curves
08:23
and geometry that you can create infusion 360 and it is
08:27
important to play around with them to make sure that
08:29
you are at least comfortable and accessing and using them.
08:32
We will be using the Spline for a few more examples,
08:36
but we will not be coming back to the iconic curve or the ellipse
08:40
at this point. Let's go ahead and finish the sketch.
08:43
And I strongly urge you to continue to
08:44
play around with exploring those sketch elements.
08:47
But for right now, if you want to save this,
08:49
you can go ahead and select save and save it into your sketching folder.
08:53
I'm going to call this Spline practice.
08:57
Once you're done playing around with sketch entities,
08:59
make sure that you do save your design one more time and then move on to the next step.

00:36
There are five different types of slots which

00:42
We've got horizontal vertical slots and then we've got our slots.
00:46

00:52
From here.
00:53
We want to select the origin and then begin dragging out the center line of our slot.
00:58
This can be at any angle you wish, for example,
01:00
we can put this at a 45° angle once we pick the
01:04
end point will then begin creating the radius of the slot.
01:09
If we don't enter any dimension values,
01:11
you can see that it's under to find if I had escaped to get off my slot tool,
01:16
I can begin moving this around and resizing it as needed.
01:19
I'm going to select the construction center line and place a horizontal constraint
01:23
and then I'm going to use my dimensions to dimension the radius value.
01:28
In this case we're going to use 25 mm and the overall length. Center to center of 150.
01:35
So we have a fully defined slot.
01:38
If we go back up to create slot and we take a look at our center point arc slot,
01:43
we first need to select the center point,
01:45
the start point and the endpoint of our slot
01:48
and then we can determine the radius value.
01:51
Once again, if we don't enter any dimensions, this is going to be under defined.
01:55
I'm gonna hit escape and note that we can still move this around.
01:59
We can use constraints and dimensions to fully define it.
02:02
For example,
02:03
control selecting the two endpoints and making
02:05
sure that they're horizontal with each other
02:07
Using dimensions to give it a radius value. In this case 150.
02:12
And we can give it a radius value of 15
02:17
and then we can determine how to dimension the ark itself.
02:20
And in most cases you'll want to use construction line geometry.
02:24
In this case we're going to go from the center point to here and I'll hit escape.
02:29
We'll turn this into a construction line using our line type option.
02:33
And then we'll use dimension to go from that
02:36
line to our horizontal and give it an angle
02:40
because we said the endpoints were horizontal. This will fully define our slot.
02:45
A slot geometry is very helpful for mechanical designs,
02:49
but often times we need to use more advanced
02:51
sketch entities if we're creating more organic type shapes.
02:54
So let's finish this sketch.
02:57
Go to our sketches folder and hide it

03:03

03:32
Once you see the spline on the screen,
03:34
you'll notice that each point we clicked has a green handle associated with it.
03:39
This is going to control the tangent C direction as
03:42
well as the weight or influence of that tangent.
03:45
C points can be added or removed by selecting them and deleting them to remove it.
03:50
Or by selecting the spline, right clicking and using insert spline foot point,
03:57
we'll escape to get off the insert tool and we can manipulate the spline points.
04:02
It's important to note that once you activate the handle,
04:05
it's going to cause an influence in the spline itself.

Again, there are many different sketch elements, things like polygons,
06:29
but we want to focus on ellipses and connick curves.
06:33
Now,
06:33
iconic curves are an interesting type of curve where
06:37
we're looking at a plane slicing through a circular cone
06:41
to create iconic curve. We want to define three points
06:45
and then we have a row value as the row value is closer to one.
06:50
We're creating much closer to a cone shape as the

06:60

07:03
we're increasing the angle that we're going through a cone.
07:07
The cone radius value is determined by the distance of the end points
07:11
and the row value is determined by moving this area
07:14
up and down or manually entering the value here.
07:17
It is important to note that you can only go up 2.99 and down 2.01.

You cannot go to one or zero. In terms of the extent of the row value.
07:29
We're gonna go ahead and right click and select OK to

accept the comic curve and if I double click on it,
07:34
the row value is shown and we can make manipulations once more.
07:40
Next let's go to create and take a look at the ellipse.
07:43
The ellipse is relatively simple to create and can offer a very nice curve result.
07:49
We're going to select a center point horizontal point
07:52
and a vertical point to define our ellipse.
07:55
We're gonna escape to get off the ellipse tool and note that we can
