30° locked rotation

[saro]

Hello.
Is there anyone who knows how to explain why in a file I have the rotation of objects locked at 30 °? It's just in a file.
I make an example:
If I have a vertical line, I try to rotate it with the ortho inserted, the first rotation is at 30 ° the second then it does at 90° regarding the first (so at 120°), normally instead of defalut should be at 90-180-270-360 right?

united command -> direction -> where there is "other" you will find the value 30 -> reset a base angle.

Is the bird global?

Okay planner... it was just that, inadvertently someone had set instead of on east on other and there was 60° set.
Thank you.
