FAWE has brush tools that allow you to build and draw from far away. When you enable a brush, it gets bound to your currently held item. You can have different tools bound to different items and up to two brushes bound to a single item.

Bind to any click: /br <brush>
Equip it to right click: /br primary <brush>
Equip in to left click: /br secondary <brush>

• /mat <pattern> - Patterns decide what is placed
• /mask <mask> - A destination mask decides if a block should be changed
• /smask <mask> - A source mask changes if a block can be placed
• /targetmask <mask> - What blocks are targeted by the brush. The default mask is !air
• /transform <transform> - A transform changes where the blocks are placed
• /range <range> - The distance you can use the brush at
• /size <size> - The size of the brush (e.g. radius 10 sphere)
• /none - Unbind tool
  Use the -h flag to change the settings for your offhand brush.

You can change the target mode to assist building in different areas (air, walls, ground etc.) Changing the //brush range can also be useful.
/br target <0-3>

• 0 = Target block
• 1 = Target point directly ahead, distance depends on pitch
• 2 = Target point, distance depends on height from ground
• 3 = Target block face

Use the mouse wheel to change brush behavior

• /br scroll clipboard <file|folder|asset url>
• /br scroll mask <mask1> <mask2...>
• /br scroll pattern <mat1> <mat2...>
• /br scroll range
• /br scroll size
• /br scroll target

Crouch (shift) and click to reset a brush.
This will for example, clear the clipboard of the copypaste brush, and reset the points in the spline brush.

With FAWE you can visualize how the brush will change blocks: /br vis <0-2>

• 0 = No visualization
• 1 = Single point
• 2 = All block changes are visualized
