Changing Drive State
You can change an end fitting's state from driven to driving, if you need to add mates to it. The drive state applies to end fittings such as flanges, tees, reducers, in-line valves. Elbows can be treated as fittings if you use drag/drop to add them to a route.
To change the drive state of an end fitting:
- Edit the route assembly but not in Edit Route mode. Exit the route, if in Edit Route mode.
- Right-click the end fitting and select Constrain sketch to fitting.
The state changes from driven to driving. You can use Assembly commands with this component or add mates to it.
If the
Constrain sketch to fitting or
Constrain fitting to sketch commands are not available, you cannot change the drive state for the following reasons:
- The fitting already has mates.
- The fitting does not allow the drive state to be changed.
- Typically, you can only change the drive state of flanges that start or end a pipeline.
Where you need to constrain the pipe but cannot change the state or use mates, you can add sketch constraints to the pipe sketch geometry. For example, adding collinear constraint to the pipeline can achieve the same result as adding a collinear mate to a tee.
