Voxel Deletion
Delete voxels using the remove shape tool.
With the delete tool enabled, when you press the left mouse button on a voxel, it will be deleted.
Dragging the mouse after clicking on a voxel can be used to delete other voxels on the same plane as the clicked face.
Voxel Creation
Create voxels using any of the shape tools.
With a shape tool enabled, when you press the left mouse button on a voxel, it will be added to the structure.
Dragging the mouse after clicking on a voxel will create other voxel on the same plane as the clicked face.
Holding down space will cause the preview voxel to remain immobile so you can easily select a face to click.

Click on an edge to rotate the shape.
Click on a face to flip the shape.
