[Me...] Posted June 9, 2021 Share Posted June 9, 2021 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 ?

[Ma...] Posted June 9, 2021 Share Posted June 9, 2021 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... 🤣 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
