How can I save a user chosen 3D shape of the object and load it back in via button presses?

Questions & Answers

I’ve managed to figure out how to save the user’s chosen position and load it back in, but I’m having some trouble understanding how to do something similar with PlayerPrefs for saving the 3D shape (since I believe PlayerPrefs only saves ints, floats, and strings). Any help is appreciated!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class cubeControls : MonoBehaviour
{    
    // Start is called before the first frame update
    void Start()
    {
    }

    // Update is called once per frame
    void Update()
    {
        /* Changing the position of the object
         * 
         */    
        // Moving the object right
        if (Input.GetKey(KeyCode.D))
        {
            transform.Translate(Vector3.right * moveSpeed * Time.deltaTime);
        }

        // Moving the object left
        if (Input.GetKey(KeyCode.A))
        {
            transform.Translate(Vector3.left * moveSpeed * Time.deltaTime);
        }
    }

    // To add button elements to the visual interface
    void OnGUI()
    {
        /* Changing the shape of the object
         * 
         */

        // Reset shape to cube
        if (GUI.Button(new Rect(50, 30, 100, 40), "Cube"))
        {
            GameObject newCube = GameObject.CreatePrimitive(PrimitiveType.Cube);
            newCube.AddComponent<cubeControls>();
            Destroy(gameObject);
        }

        // Changing to cylinder
        if (GUI.Button(new Rect(50, 90, 100, 40), "Cylinder"))
        {
            GameObject newCylinder = GameObject.CreatePrimitive(PrimitiveType.Cylinder);
            newCylinder.AddComponent<cubeControls>();
            Destroy(gameObject);
        }

        // Changing to sphere
        if (GUI.Button(new Rect(50, 150, 100, 40), "Sphere"))
        {
            GameObject newSphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
            newSphere.AddComponent<cubeControls>();
            Destroy(gameObject);
        }

        // Saving
        if (GUI.Button(new Rect(700, 330, 50, 30), "Save"))
        {
            // Saving the object's position 
            PlayerPrefs.SetFloat("xCoord", transform.position.x);
            PlayerPrefs.SetFloat("yCoord", transform.position.y);
            PlayerPrefs.SetFloat("zCoord", transform.position.z);

            // Saving the object's shape

        }

        // Loading
        if (GUI.Button(new Rect(770, 330, 50, 30), "Load"))
        {
            transform.position = new Vector3(PlayerPrefs.GetFloat("xCoord"), PlayerPrefs.GetFloat("yCoord"), PlayerPrefs.GetFloat("zCoord"));
        }
    }
}

I would Switch gameobject tag when changing the primitive and later depending current tag save tag in playerprefs, later just when you want to load the gameobject again just compare playerprefs shape

 //assign tag
 newCube.tag = cube;
 //set tag in player pref
 PlayerPrefs.SetString("shape",gameObject.tag)

 //load depending tag
 switch(PlayerPrefs.GetString("shape"))
 {
     case "cube":
     //CREATE PRIMITVE AND MOVE IT TO X Y Z SAVED
     break;
  }
