The /sch command has five primary options:
/sch list <search> – displays a list of schematics in the schematics folder that contain the characters in the <search> parameter. The display shows the width, length and height of the schematic (WLH).
/sch show <schematic name> – shows where the schematic will be placed in your world before you actually load the schematic. The direction the player is facing establishes the direction in which the schematic outline will be shown. Arrow keys allow you to move the location where the load will take place.
/sch load <schematic name> – loads the schematic. The direction the player is facing establishes the direction in which the schematic will be placed. If you used /sch show to place the schematic, remember to face in the same direction as when you entered the command. Note that you have to have at least one GOLD INGOT in your inventory to pay for the schematic.
/sch undo – removes the schematic from your world and restores the space to its original content. You don’t get your GOLD INGOT back.
/sch save – saves the set of blocks captured by the Schematic Stick.
