Composer

The Composer is a machine added by RFTools. It combines multiple Shape Cards into a single Shape Card. Shape Cards are combined in order from top to bottom. There are three modes for each shape card added. Addition(+), Substraction(-), Intersect(^). Intersect only leaves parts that collide. First card is always the base shape (Only addition mode). The bottom-most slot is the output slot and requires a Shape Card to be entered. Switching the Shape Card in the bottom-most slot makes another card of the current setup; make sure the dimensions of the Card are correct.
