If you made a coaster you really like and want to keep for later, you can save its design as your very own custom blueprint.

You can do so in two ways:

- After testing your coaster in the park editor, tap on the Save button.

- From the Assign Blueprint menu, accessed by selecting a placed coaster. Tap on the crane button, then on the Blueprint button.  The first items on the list is the button to save your design. This will create a card in the list of Blueprints that you can drag to re-assign when you want.

Note that you can only save one design by coaster type. If there is already a blueprint saved, it will ask for a confirmation to replace the already-placed design.
