How can I make a dragging part script where it moves a part onto the surface of another part?

[Prettyovalheart (PrettyHeart)]

I’m trying to create a dragging tool, similar to the old hopperbin gametool. I just can not figure out how to make sure a part is not clipping inside of another part, and make sure it can easily snap onto the surface of a part. Here is an example of what I’m trying to accomplish.

One way is to use the default Dragger which mimics the old game tools which you seem to want like below:

Create on Roblox

Classic Build Tools - Roblox

But otherwise for the specific question for clipping into the part this should help:

Preventing parts from embedding into other things with a custom dragger

What you want is called a safe move. After rotating or when moving a part to the mouse’s hit CFrame, use :MoveTo(). This may mean making a temporary model to contain the selected part. Another option would be to use the Dragger service.

Thanks for the help! I’ll look into it.
