Mouse Drag 3d Objects in Unity, Tutorial at Devsplorer at https://youtu.be/bK5kYjpqco0

Move3D.cs

using System;
using UnityEngine;

[RequireComponent(typeof(Collider))]
public class Move3D : MonoBehaviour
{
    private Camera mainCamera;
    private float CameraZDistance;

    void Start()
    {
        mainCamera = Camera.main;
        CameraZDistance =
            mainCamera.WorldToScreenPoint(transform.position).z; //z axis of the game object for screen view
    }

    private float counter = 0;

    void OnMouseDrag()
    {
        Vector3 ScreenPosition =
            new Vector3(Input.mousePosition.x, Input.mousePosition.y, CameraZDistance); //z axis added to screen point 
        Vector3 NewWorldPosition =
            mainCamera.ScreenToWorldPoint(ScreenPosition); //Screen point converted to world point

        transform.position = NewWorldPosition;
    }
    

}

Is there any way to add it some sort of delay to the movement, so it feels more natural??

hey it's 2 years late and you probably don't care but I would imagine you would want to update the position of the object to the position defined in OnMouseDrag() through an update method using a percent of the difference between the two transform.position values
