After a default node that specifies either a BOM or a route has been inserted, you can add new BOM lines to the BOM or new route operations to the route. You can do this by adding the new BOM nodes or route nodes under the default node. The complete BOM or route in the product model then consists of the BOM or route that was specified in the default node, plus any extra nodes that were added separately to the modeling tree.

Default routes work in a different way. The selected default route functions as a template for route nodes that are subsequently added to the modeling tree. Therefore, the specification of a default route does not in itself add a route to the product model. Instead, the default route has a supporting function for the subsequent creation of route nodes.

When a route node is created in connection with a default route, the Route numberfield should be filled in with the route number of the default route. After this is done, you should select an operation. If the selected operation is a part of the default route, the default route's next operation number is automatically shown on the operation line. Operations can be freely picked from all the operations that make up the default route. Specific operations can be left out, and operations that are not part of the default route can be added before the default route's first operation, or after its last operation.

The ordering of operations in the default route cannot be changed, and new operations cannot be inserted between the operations that make up the default route.
