选择工具

This section covers selection tools and their options. An option that is generic to all selection tools a concept known as boolean operations. The default option is ‘add’

Boolean Operation	Description
Add	Adds the selected area to the current selection
Subtract	Subtracts the selected area from the current selection
Replace	Replaces the current selection with the selected area
Intersect	Selects only the area that overlaps with the current selection

Note: At very large scales non-cuboid selections become less performant due to the complexity in keeping track of the entire region. If you need to perform an operation on a very large area it is recommended to use a cuboid selection and encompass the entire build.
