Boxcast/Raycast Orientation

I started with the API Scripting reference's Physics.BoxCast example code: [https://docs.unity3d.com/ScriptReference/Physics.BoxCast.html] ...and it works great... until the game object rotates, see:

I know I've been something crazy for other people to try to look at, but here are some snippits of one ray/boxcast:

         public float w = 9f;
         public float h = 34.5f;
         public float d = 24;
         bool m_HitDetectFORE;
         RaycastHit m_HitFORE;
         float meausure_MaxDistance = 144f;
     
     void FixedUpdate() {
             
             m_HitDetectFORE = Physics.BoxCast((transform.position + new Vector3(w / 2, h / 2, -d)), new Vector3(w / 2, h / 2, 1f), -transform.forward, out m_HitFORE, transform.rotation, meausure_MaxDistance);
             if (m_HitDetectFORE) { Debug.Log("FORE Hit : " + m_HitFORE.collider.name); }
     }
     
     void OnDrawGizmos() {
             Gizmos.color = Color.cyan;
     if (m_HitDetectFORE) {
                      Gizmos.DrawRay((transform.position + new Vector3(w / 2, h / 2, -d)), -transform.forward * m_HitFORE.distance);
                 Gizmos.DrawWireCube((transform.position + new Vector3(w / 2, h / 2, -d)) + -transform.forward * m_HitFORE.distance, new Vector3(w, h, 1f));
             } else {
                      Gizmos.DrawRay((transform.position + new Vector3(w / 2, h / 2, -d)), -transform.forward * meausure_MaxDistance);
                 Gizmos.DrawWireCube((transform.position + new Vector3(w / 2, h / 2, -d)) + -transform.forward * meausure_MaxDistance, new Vector3(w, h, 1f));
             }

I have benefited enormously from reading the wealth of existing answers on this forum, but I can't piece together what's going on with this contraption. Thanks!
