I can’t work out how to snap a tool back to the center… so my symmetry is shot. How do I do this? I’ve looked on line but to no avail.
Hold Shift while you’re rotating the model. It will automatically snap to the nearest axis.
And symmetry is always relative to the model’s coordinate structure rather than to the canvas. So if you have symmetry turned on it will always work right no matter what direction the model is rotated on the canvas.
