00:03
In Fusion, you can use parameters to drive and edit multiple dimensions from a single named parameter.
00:10
Once you create a predefined parameter with a specified value,
00:14
you can assign that parameter to multiple dimensions, instead of setting values individually.
00:20
Editing this parameter value will then propagate the changes across all dimensions with the same parameter reference.
00:27
To access the Parameters dialog, on the Design workspace toolbar, click Solid > Create Sketch, if you are not already in Sketch mode.
00:37
Then, click Sketch > Modify > Change Parameters.
00:42
Favorites are commonly used parameters that you want to access quickly.
00:47
For a more complex design, these can be particularly useful.
00:52
User Parameters are created by you, and if you already have some known dimensions,
00:57
you can start populating these even before creating a sketch.
01:01
Model Parameters are automatically generated when you create any 2D or 3D geometry.
01:07
If you expand this category, you see expression values that match the geometry created in your design.
01:14
Press Esc or click OK to close the Parameters dialog.
01:19
To edit a dimension placed on the sketch, double-click the dimension,
01:23
type a new value, and press Enter.
01:27
If you have dimensions that are specific to certain geometry, then simply entering values is a reasonable workflow.
01:34
However, if you have multiple geometries that share a common value
01:38
—even across multiple sketches—
01:40
setting up named parameters may be more efficient.
01:43
To open the Parameters dialog again, type “S” to open the Toolbox,
01:49
type “Parameters”,
01:51
and then select Change Parameters in the search results.
01:56
In the Parameters dialog, click + User Parameter to open the Add User Parameter dialog.
02:03
In the Name box, type “Radius”.
02:06
Set the Unit to mm, and in the Expression box, enter a value of 20.
02:13
You can also add a Comment to clarify the purpose of the parameter.
02:17
Click OK to complete the setup.
02:20
You can see the parameter now populated under User Parameters, and you can start using it in your design.
02:27
You can also create a parameter while creating a sketch feature.
02:31
Instead of entering a dimension, type a parameter name followed by the equals symbol and the value, and then press Enter.
02:39
In this case, enter “L1=20”.
02:43
Open the Parameters dialog, and you can see that this parameter is automatically added under Favorites.
02:50
This is useful if you want to quickly set and name parameters while modeling.
02:55
Close the Parameters dialog.
02:57
To use the parameter that you set up earlier, double-click the radius value on the lower arc,
03:03
and then start typing the parameter name—in this case, “Radius”.
03:08
In the filtered list of suggestions, select the Radius parameter to reference it.
03:13
The name appears in the box and turns black to indicate that it is a valid parameter.
03:19
Press Enter to confirm.
03:22
The dimension updates to match this parameter value.
03:26
You can confirm that you are using a parameter if you see fx preceding the value,
03:31
and if double-clicking the parameter shows the parameter name.
03:35
To edit the parameter, open the Parameters dialog, double-click the Radius value, and enter a new value of 30.
03:44
Click OK.
03:46
The geometry updates without entering the dimensions on the canvas.
03:51
To see how parameters can save you time, first delete a constraint on the canvas.
03:56
The sketch turns blue, indicating that it is not fully constrained.
04:01
On the toolbar, click the Dimension tool, then select the arc.
04:07
Start typing “Radius”, select the Radius parameter, and press Enter.
04:14
The Radius parameter is now referenced in two places in your sketch.
04:19
Open the Parameters dialog and change the value to 25.
04:24
Note that you only need to edit one value, and any dimensions with that parameter reference updates accordingly.
04:31
Setting up and using named parameters is particularly useful with more complex assemblies,
04:36
but it can save you time on nearly any design.
