Additional Auxiliary Tools
Minimum requirement: Qubicle Basic Edition
The additional Auxiliary Tools offer more selection options and allow you to resize a Bounding Box.
Paint Selection freely paints a selection of voxels. Shift adds to the selection and Ctrl subtracts from it.
Box Select selects voxels in a 3D area. Drag a selection, use the transform handles to resize it and hit Enter to finalize the selection. The same operation can be completed with Shift to add and Ctrl to subtract from the selection.
Resize changes the size of the Matrix Bounding Box by adjusting the transform handles. Please note that once you release a transform handle the changes are applied automatically. To undo a resize operation use Edit > Undo.
