The Shape Card (Clearing Silk Quarry) is an item added by RFTools. It is used to instruct the Builder to operate in Quarry mode, replacing mined blocks with air blocks. Resources are mined with the effect of Silk Touch.
The Shape Card (Clearing Silk Quarry) inherits the properties of a Shape Card, providing the player with a range of different shapes and the ability to specify distances and offsets. Additionally, the Shape Card (Clearing Silk Quarry) can be configured to automatically void a number of common blocks such as Dirt and Cobblestone.
