Buildcraft

Build Wand – Select two points and fill the area with any block in your offhand. 


Copy Wand – Copy a region of blocks and save it as a Blueprint item.


Paste Wand – Paste your Blueprint anywhere, with 90° rotation support and a live preview. Block orientations (stairs, doors, torches, etc.) are preserved correctly.


Circle Wand – Draw a perfect circle or hollow sphere with any block.


All tools consume blocks from your inventory in Survival mode and will warn you if materials are insufficient. Creative mode bypasses consumption.
