How to add roblox tools in game?

Hey. I was just wondering how games manage to add Roblox tools into their game, here’s the picture so you get what I mean.

Help is appreciated! Thanks.

You can use InsertService load asset.

game:GetService("InsertService"):LoadAsset(ID goes here).Parent = workspace

This will insert the item in workspace in a Model named “Model”.

I meant that rotate tool. How would I add that?

I guess you could add Kohl’s admin into your game and type F3X into the command bar; that will allow you to edit blocks

You will need to use Handles and ArcHandles.

What are they, Can you explain or send a link where I can read about them?
