In Fusion, you can use contact sets to push or limit components by linking joints in an assembly.
00:10
Once contact sets are defined,
00:12
from the Browser, you can remove or apply contact sets to all bodies in the design, and suppress individual sets.
00:20
In this example, the drill press shown has no motion limits on the assembly, so it can have components that pass through one another.
00:28
One method of establishing a range of motion for the assembly is to use contact sets.
00:34
On the Design workspace toolbar, Assemble tab, expand Assemble and select Enable Contact Sets.
00:42
Contact sets enable the assembly to move freely until selected components come in contact with one another.
00:49
Then, the motion is limited by their interface.
00:53
You can also Enable All Contact, but unless it is a very small assembly, this can be prohibitive and slow performance dramatically.
01:01
In the Browser, right-click the Contact sets folder and select New Contact Set.
01:07
This opens a new dialog, where you select each member of the contact set.
01:12
First, create a contact set to establish how far down the drill chuck can go.
01:18
Select the top component, which is the Shaft carrier, and then the top of the Carriage, which is the sheet metal component.
01:25
Click OK to create the contact set.
01:28
In the Browser, under the Contact sets folder, you now see a ContactSet.
01:34
In the model, move the handle down, and it stops at the top of the carriage.
01:39
However, move the handle up, and the chuck extends through the carriage.
01:44
Right-click and create another New Contact Set.
01:48
This time, select the drill chuck and the lower bearing.
01:54
Click OK.
01:56
Contact sets can be renamed as needed; which is helpful in a large assembly.
02:01
Move the handle up and down again.
02:04
Now, it stops at full depth and at full retraction.
02:09
If you create a contact set and move the part too fast or continue to push through, in certain cases, parts may pass through each other.
02:18
If that happens, just pull the model back up to its original position quickly,
02:22
then move the part more slowly to help ensure that the contact is made.
02:27
Revert the position.
02:30
When you place the pointer over the Contact sets folder in the Browser, you see two icons:
02:37
Disable All Contact turns off contact analysis for all components
02:41
and Enable All Contact activates contact analysis for all components in the design.
02:47
For individual contact sets, you can use the Suppress icon to suppress the contact set.
02:53
Note that these options are also available in the context menu of each contact set.
02:59
For example, if you right-click and Suppress the first set, you can move the handle all the way down and the contact is ignored.
03:07
Revert the position and Unsuppress the contact set.
03:12
Contact sets can be used in several different ways to actuate mechanisms or to limit mechanisms.
03:19
The use of contact sets is intended to replicate what will happen in the real world within your digital design.
