Merlin’s Forge commands allow you to save and load schematics. They are stored in the .minecraft/schematix folder. 

/str list <search criteria> lists the schematics with those criteria as well as a short description, length/width/height and price.

/str load <schematic name> loads the schematic to the left of a required Redstone Block that sets the position for the load.

/str save <schematic name> saves the space defined using Merlin’s Block Marker to the schematix folder.
