create parameter based sketches.
00:06
After completing this video, you'll be able to create a user parameter,
00:09
create a construction plane.
00:11
Use circle and rectangle and link sketch dimensions and parameters
00:17
Infusion 3 60. We're gonna get started with a new untitled document.
00:22
We want to expand our document settings and note that
00:24
we are going to be using the metric unit system.
00:28
When we're talking about creating sketches and designs in fusion 3 60.
00:32
Oftentimes the dimensions are added directly in the
00:35
sketch or during creation of a feature.
00:37
But when pre planning out models,
00:40
creating what are called user parameters can be a helpful addition to
00:44
figure out a way to control your designs in one place.
00:47
So for this example we're going to start by going to modify and change parameters.
00:54
The parameters dialog will contain all the parameters used
00:57
in sketches and features but it also allows us
00:60
to create user parameters ahead of time or after
01:03
the fact and link them to the various values.
01:05
So we're gonna hit the plus icon to get started
01:08
and we're going to create a new user parameter.
01:10
It's important to note that there are
01:12
syntax constraints when naming user parameters.
01:15
For example, I want to create a plane offset and I'm not able to use the space.
01:21
I either have to use underscore
01:23
or I can simply put a capital O for the next letter.
01:28
Then we can enter a value or an expression that's going to be used in this case.
01:32
The units are still mm and the expression is going to be 500.
01:37
This is going to evaluate to 500. And we can say, Okay,
01:41
I'm gonna select OK. And then I want to create a new offset construction plane.
01:46
I'm going to select this plane here which is Y. Z. Or my right plane.
01:51
And once the dimension or distance dialog boxes active,
01:55
I'm going to begin typing in P for plain and you
01:58
can see that my user parameter plane offset is listed here.
02:03
I can hit enter to accept that double click the mouse
02:06
wheel and you can see that if I show my origin,
02:08
double click the mouse wheel again that I now
02:11
have my origin and my 500 millimeter offset.
02:15
What I want to do from here is create some
02:17
additional parameters and link them to values such as sketches.
02:20
So from modify change parameter.
02:23
I want to create some length, width and diameter parameters.
02:27
So we'll start by typing in length,
02:31
This is going to be 200.
02:35
I'm going to repeat the process for width.
02:40
This is going to be 200
02:42
as well and we're gonna create one for whole _ DIA for diameter.
02:48
And this is going to be 50.
02:53
Now I want to create a new sketch and I'm going to select my Y Z plane,
02:57
right click and select create sketch
03:01
from here. I want to create a center point rectangle.
03:04
So we'll select centerpoint,
03:06
place it at the origin and as the dimensions are displayed,
03:09
I'm gonna go ahead and type L.
03:11
For length and I'm going to hit enter to accept length tab to go to the next dialog box,
03:18
W for width, enter and then I can enter to accept that
03:22
I'm going to use the center diameter circle right at the origin.
03:27
And I'm going to hit H for hole and again enter to accept and enter one more time.
03:34
I'm gonna finish the sketch
03:35
and then I want to use extrude.
03:38
We'll select this profile and for the extra distance I'm
03:41
going to select to object and select our plane.
03:45
Note that we could also use the dimension
03:48
directly inside of the extent dialogue for example,
03:52
for distance instead of using 500
03:55
or using our plane as an object.
03:57
We can simply type in p for plane offset and it'll have the same effect.
04:02
So depending on whether or not you're extruding up to a plane or
04:06
another reference or you want to simply enter the value directly in here.
04:10
Both options will provide the same result.
04:14
Now we have our design but what can we do with it?
04:17
Well,
04:17
we can go back to modify change parameters and let's go ahead and minimize
04:22
this a little bit and pull it out of the way so we can see
04:25
If I decide to decrease the plane offset value to say 200.
04:30
The entire design is going to shorten.
04:33
If I decide to make the length a bit longer. At 500, you can see the design updates.
04:38
If we make the hole diameter larger. Again the design updates.
04:42
If we make the user parameter for with a bit taller, everything updates.
04:47
So making sure that we take the time to reference our sketches
04:51
properly to the origin and any other sketch entities and make sure
04:55
that we understand how we can use these user parameters to our
04:58
advantage will help us build robust models that can be updated easily.
05:03
It does take a little bit of pre planning and thought.
05:06
But even if we create a sketch for example on the top face here
05:11
And we use another circle this time I'm going to go ahead and
05:15
place it roughly in the center and I'm gonna add a dimension.
05:19
This can be done with D on the keyboard
05:22
and select the circle and let's say 150
05:25
and I'm gonna go ahead and place this a distance of half of the overall thickness.
05:32
So remember that value was our plane offset. And I'm gonna use divided by two.
05:37
So this will place it exactly in the middle of that plane offset.
05:40
However,
05:41
we also need a horizontal vertical constraint to make sure that it is fully defined.
05:47
So now we can use extrude
05:49
and we can add this boss to the top.
05:52
But what if we decided that we wanted a user parameter to
05:55
define that if we go back to modify and change parameters,
05:59
we can expand our model,
06:01
we can expand our sketches and features and we can find the
06:05
values that were used for example 100 and 50 or 75.
06:10
We can use our favorites to place those at the very top.
06:14
Or we can use new user parameters in this case whole underscore dia to
06:21
Value of 75 and then we can re associate this. So type in H for a hole diameter.
06:29
Or we can select hole diameter too and make that reference here.
06:34
So we can rename this whole too and we can
06:38
reset the expression value to be our hole diameter to.
06:43
That allows us to re link those values or expressions.
06:47
It just takes a little bit of extra time.
06:49
This can also be done back at the sketch level.
06:52
If we were to double click on the original sketch
06:54
we can double click on the diameter value or the
06:57
radius value and we can simply link it here whole
07:01
diet to enter and you can see the value there.
07:05
Once we finish the sketch we can update everything from the
07:08
user parameters And now the design again is parametric in nature,
07:11
making it easier for us to update.
07:14
It is important to note that not all designs will
07:17
make use of creating user parameters ahead of time.
07:20
There are some cases where you simply must create your
07:23
dimensions on the fly but in a lot of cases
07:26
you can do a little planning create parameters ahead of
07:28
time and have an easy way to drive your design.
07:31
Let's go ahead and save this. And in this case I want to create a new sub folder.
07:36
So we've got our intro here and I'm going to
07:39
select new folder and I'm going to simply call it sketching
07:43
when a double click on that.
07:44
And then we're going to create this as user parameter practice.
07:51
So now we've saved our new design in a new folder in our data panel.
07:55
And we have a basic understanding of how we can use user parameters to our advantage.
08:00
Once again,
08:01
it's important to play around with these and figure
08:03
out how they can be used in your designs.
08:06
Once you're done with that,
08:07
make sure that you have saved your design and you can move on to the next step.
00:02
create parameter based sketches.
00:06
After completing this video, you'll be able to create a user parameter,
00:09
create a construction plane.
00:11
Use circle and rectangle and link sketch dimensions and parameters
