# Brush Flags

A brush can have several flags which change the behavior of the brush and the placement of the schematics. All flags have a short form.

#### Placement

A schematic can be placed in several method. Before a schematic is placed, we modify the origin of the schematic. The origin position is equal to the block you pointed at with the block. The origin is always at the x and z center of your schematic, but we allow you to change the y value which is most important.

**Middle**: The origin will be in the y center of the schematic **Bottom**: The origin will be on the lowest point of you schematic **Drop**: The origin will be at the lowest non air block in your schematic. This is the default value. **Top**: The origin will be on the highest point of you schematic **Raise**: The origin will be at the highest non air block in your schematic

`-placement:type` `-place:type` `-p:type`

Hint you can also use only the first letter of the type. This means that: `-p:d` is equal to `-placement:drop`

**YOffset**

The y offset is applied after the placement changes. You can raise or lower a schematic before pasting. This is useful for trees if you want be sure, that they will not be placed on top of gras.

`-yoffset:number` `-yoff:number` `-y:number`

#### Replaceall

On default the schematic brush only replaces air. We don't want to destroy existing structures. This will change the behavior. So we can replace blocks, which are solid.

`-replaceall` `-repla` `-r`

#### Placeair

On default we don't place air block. If you want to change this use this flag.

`-includeair` `-incair` `-a`
