Seriously though once the gyro is mastered it makes life a lot easier. I spent months using the gyro without fully understanding it. Most of the time it would do what I wanted but a lot of the time it wouldn’t.
So I just spent an hour one day resolving to understand how it works. It’s really worth it because once you’ve got it you never have to think about it again. It saves a lot of time in the long run.
The first thing to be aware of is that in the three modes: Move Size Rotate not all the coloured bits work.
Basically you have three axes, and three planes. The axes are Cyan Magenta and Yellow Which correspond to the X Y Z axes. And the planes are Red Green Blue which correspond to the X Y Z planes.
If you understand colour theory you will notice that RGB is the opposite of CMY. This makes it easy to keep in mind which plane or axis is which. Just think RGB XYZ CMY XYZ.
Now you have that sorted. The next thing is to realise that when an object moves further away from you it does not change size. This can make it very confusing, because if an object moves up it is not possible to tell which plane it is moving on by looking at the object.
But if you move it using the coloured rings you can be sure of which way it is moving no matter what it looks like.
The move mode is the most confusing. That is the one nearest to the cross, towards the left.
When you are in this mode if you click and drag on one of the CMY axes the object will only move on that single axis even if your cursor wanders. However if you miss the cross and touch one of the RGB planes then the object will move on the two axes that are on either end of the RGB segment. This is perhaps the most confusing aspect of the Gyro and it has baffled many very experienced users. It had me going nuts one day until I resolved to understand it. Instead of dragging on a plane, (RGB) many users prefer to drag on the two axes separately. You really have to play around with this to fully understand it.
The thing to watch out for in the Move mode is that you always only ever touch a cloured bit, because if you touch inside the Gyro it will immediately orient itself to the surface normal of any object it touches or it will orient itself to the background. Then you will have to go back to rotate mode to put it back to where it was. This gets very frustrating until you get used to it. The grey ring is alway parallel to the background, which is the same as the blue ring when the object is first drawn.
The mode on the far right is the Rotate mode and you can Rotate around the three planes RGB by clicking and dragging on a plane. If you click on an axis CMY nothing will happen at all, you won’t be able to move it.
If you click and drag inside the gyro in the Rotate mode AND you are NOT touching a coloured bit then you can free rotate in any axis or combination you choose. But the thing to remember with the rotate mode is that when the object is first drawn or if it reorients itself to the background, so the blue plane (Z) is parallel to the screen, you can’t rotate it on a single plane UNTIL you first ‘free rotate’ it a bit. If you don’t realise this you can wonder why it is not working.
In the Resize Mode (that’s the one between the Move, and Rotate) You can click and drag outside the gyro to Resize. If you click and drag on an axis (CMY), it will resize only in that axis. Good for stretching an object. You can also click a plane (RGB) and it will resize along two axes. You must keep an eye on the coloured bits because if you click near a plane (RGB) the plane will highlight and then the object will only resize in two directions instead of all three at once.
That’s about it.
