A Pattern is an item that is used in autocrafting. It stores the recipe that should be autocrafted.

Hold SHIFT to see the output of the Pattern displayed on the item texture.

Oredict mode

The Pattern can be configured to be a oredict pattern. Instead of extracting the exact item, it'll try to extract equivalent items according to the oredict as well.

Blocking mode

When configured as a blocking mode pattern, this pattern will only allow to run autocrafting one-at-a-time.

Clearing a Pattern

Use SHIFT + right click in your inventory while holding the Pattern to clear it.

Modifying the Pattern

If the Pattern is a regular crafting pattern, one can modify it by re-inserting it into the output slot of the Pattern Grid.
