A single or multiple Blank components may be used to perform complex rotations or transformations within your model. A single Blank may be used to perform a combination of X, Y, and Z axis rotations in a single component. However, you should note that the Blank will apply these rotations in the order X first, then Y, then Z. This is done intentionally so that you can always alter the angles without losing track of how you got there. If you want to perform multiple rotations about different axes in intermediate frames, then using multiple Blanks is the way to go.
