OnDrawGizmos Debug.DrawLine position is pinching when rotated.
I have no idea how to explain this question so this title is a mess. I am making a clamp, and I am trying to get the debug to show the max angle a object can rotate.

public bool yActive = true;
public Vector2 yRotation = new Vector2(0, 0);
public bool zActive = true;
public Vector2 zRotation = new Vector2(0, 0);
[Header("Debug")]
public bool debugActive = true;
public float distance = 1;

{
if (!targetObject)
{
targetObject = this.gameObject;

parentObject = targetObject.transform.parent.gameObject;
}
}

When the X is rotated the Z debugs clamp together. See picts
How its supposed to look
This is what happens when I rotate the parent. I want the debugs to stay pointing above the parent object no matter what rotation its at.
