# Adding and Removing Paths

Adding and removing paths can only take place on product or sum constraints. Other constraints have a set number of paths and thus can't be changed. Addition and removal of paths will only be saved if the change still makes a valid constraint.

## Adding a Path to a Constraint

To add a path to a constraint, right click on the constraint in the information tree and select Add Path to Constraint. This will bring up the path selection interface that can be used in the same way as during the initial path selection.

## Removing a Path from a Constraint

To remove a path from a constraint, right click on the path to be deleted in the information tree and select Remove Path from Constraint.
