Reply To: Unable to figure out the rotation of lid (wood & metal) back to exact closed position part of vid-approx 6:32 of blocking metal pieces chap.

Thanks for posting your file! As I’d hoped, you’ve left it in the perfect state to be fixed:

Essentially you just want to negate the X rotational value:

1. With both top pieces selected (rim as active), hover over the X rotation value and hit CTRL + C to copy.
2. Make sure you’re using the 3D cursor as the pivot.
3. Hit R to begin rotation and then CTRL + V to paste the value into the rotation operator. Note that you can press the “-” key to negate the value if it rotates in the opposite direction as desired.
4. Hit ENTER and you can see that the operator has inherited the pasted value.
