Hello, People I am trying to get model angle degree from 0 to 360 is there any way to do that,  
I am using Transform Controls and when I rotate model I want to get angle from 0 to 360  
I am struggling because of Euler gives me only range from 0 to 180 and -179 to 0 and I can’t detect model is on 0 degree or 360 degrees.  
Advanced Thank You

I think this should help? TransformControls rotation is done using quaternions, so it’s not that straightforward to read them.

I coped the code and this is what I have but still it is not woriking any Idea what am I doing wrong ?

if (mode === “rotate”) {  
const euler = new THREE.Euler();  
const rotation = euler.setFromQuaternion(this.picked\_asset.quaternion);  
console.log(rotation);  
const radians = rotation.x \> 0 ? rotation.x : 2 \* Math.PI + rotation.x;  
const degrees = THREE.Math.radToDeg(radians);

(1) But wait - you are trying to _read_ the model rotation in transform controls, or _write_ it to the model properties as an angle between 0 and 2π ? It looks like you are modifying control’s code - so just in case, second option is not possible (or not practical, at least.)

(2) `Euler gives me only range from 0 to 180 and -179 to 0` - without copying the code, just apply it to what you’ve got there. If angle is between 0° and 180°, use that value as the rotation. If value is between -179° and 0°, add 360° (2π) to it - it will result in a properly adjusted angle (-90° will equal 270° etc.)

(3) Also:

0° is always equal 360° 🤔

Would you tell us?

So the rotation is represented as @mjurczyk described you need to covert that. To recive it from 0-360
