 So, you don't know how to spin. Not a problem. Spin controls are very similar to the scale controls. The origin of the spin is determined over here, and how it spins is controlled over here. No alignment means the rotation is smooth, 15 degrees means it will snap every 15 degrees, and if you want a custom amount of snap, like 45 degrees, you can set that right here. Aligned to axis means the position of the pivot will depend on the world position and not the mesh. Mesh center puts spin origin on the middle of the object, polygon center puts the spin origin in the middle of whatever face you click, axis center puts the spin origin in the middle of the world position, clicked center puts the origin where the mouse was when you left clicked, local symmetry puts the origin in the middle of your target. So, if your target is set to polygroup island, the origin is going to be in the middle of the group of faces that are all the same color as the one you clicked. And clicked polygon corner is like clicked polygon, except it rotates around the corner of the polygon you clicked. Hope that helps, and as always, hope you have a fantastic day, and I'll see you around.
