I have a building mechanic in my game and when you press the build button the prefab follows your mouse and when you click it places there. The problem is it rotates according to what the mouse is on, for example if my mouse is on a tree side the object will rotate so its not clipping inside and it will rotate to match the tree

I've tried using a rigid body to lock to rotation and I've also tried using a rotation constraint but that didn't do anything.

using UnityEngine;
using UnityEngine.AI;

public class GroundPlacementController : MonoBehaviour

 [SerializeField]
 private GameObject placeableObjectPrefab;
 public NavMeshObstacle nav;




 [SerializeField]
 private KeyCode newObjectHotkey = KeyCode.A;

 private GameObject currentPlaceableObject;


 private float mouseWheelRotation;






 private void Update()
 
 HandleNewObjectHotkey();
 nav = GetComponent<NavMeshObstacle>();
 if (currentPlaceableObject != null)
 
 MoveCurrentObjectToMouse();
 RotateFromMouseWheel();
 ReleaseIfClicked();



 
 

 private void HandleNewObjectHotkey()
 
 if (Input.GetKeyDown(newObjectHotkey))
 
 if (currentPlaceableObject != null)
 
 Destroy(currentPlaceableObject);

 
 else
 
 currentPlaceableObject = Instantiate(placeableObjectPrefab);




 
 

 


 private void MoveCurrentObjectToMouse()
 
 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);


 RaycastHit hitInfo;
 if (Physics.Raycast(ray, out hitInfo))
 
 currentPlaceableObject.transform.position = hitInfo.point;

 currentPlaceableObject.transform.rotation = Quaternion.FromToRotation(Vector3.up, hitInfo.normal);
 var yourGridSize = 2.2f;

 var currentPosition = currentPlaceableObject.transform.position;
 currentPlaceableObject.transform.position = new Vector3(((currentPosition.x - (currentPosition.x % yourGridSize)) / yourGridSize) * yourGridSize,
 ((currentPosition.y - (currentPosition.y % yourGridSize)) / yourGridSize) * yourGridSize,
 ((currentPosition.z - (currentPosition.z % yourGridSize)) / yourGridSize) * yourGridSize);

 currentPlaceableObject.GetComponent<NavMeshObstacle>().enabled = false;
 if (currentPlaceableObject.name == "roof_pyramid")
 
 print("hi");
 




 
 

 private void RotateFromMouseWheel()
 
 Debug.Log(Input.mouseScrollDelta);
 mouseWheelRotation += Input.mouseScrollDelta.y;
 currentPlaceableObject.transform.Rotate(Vector3.up, mouseWheelRotation * 90f);
 print(mouseWheelRotation * 90f + "rotation");

 

 private void ReleaseIfClicked()
 
 if (Input.GetMouseButtonDown(0))
 

 currentPlaceableObject.GetComponent<NavMeshObstacle>().enabled = true;
 currentPlaceableObject.transform.Rotate(0, mouseWheelRotation, 0);
 print("disabled");
 currentPlaceableObject = null;
 print("removed prefab");
