CFraming by exactly 90 degrees causes issues like this. If you rotate the X axis 90 degrees it aligns with the Y axis and changes done to either of those may affect the other. It’s called gimbal lock and causes weird numbers like this.
There are plenty of topics on the forums about gimbal lock.
Is the item placed at 90 degrees in the workspace, or is it actually placed at strange angles?
What I meant is that with the Orientation of -63.38, -161.383, -179.998 how does the item look in the workspace? Does it seem to be ‘square’ to the workspace? I’ve noticed CFrames with numbers like yours that mostly appear to be very close to the 0, 90, -90, and 180 angles in the workspace.
All I did was search ‘gimbal lock’ in the forums before, or just google it to learn what it is.
