Reference axis and direction of rotation

[[Me...]]

Hello everyone,
I have a question, does anyone have a graphical representation of the angles W1 and W2 for planes.
As an example, the angle specification W1 (Z / X). Projected angle 1. In this case, the projection takes place in the X / Z plane, the reference axis is X. The direction of rotation is counter-clockwise. So far OK.
Angle specifications W1 (X / -Y) in the explanation cause problems. Note the "-" in front of the reference axis Y.
Can someone help ?

Hello,
I might be totally wrong, but as I understand it in your case of X/-Y you just read
the X angle clockwise instead of counter-clockwise.
If that was even the question... 🤣

The easiest way I've found to remember this is convention is that for a positive value the end of the second axis in the label is tilted towards the end of the first axis.
So for example:
For a positive angle, W1 (Z/X) the positive end of X will be tilted towards +Z
For a positive angle W1 (X/-Y) the negative end of Y will be tilted towards +X
