How does Handle dragging work? (mouse movement to 3D coordinates)
Asked by

I'm working on a part placement tool, like many building games have. Moving the object through X and Z axis is fine, as long as there is some baseplate to be detected by mouse.Hit.
When it comes to Y axis, I wanted to make a system that locks the object position in X and Z, so I can control its height (like RCT building controls, if anyone remembers those).
The problem is that I don't know how to transform mouse movement into precise 3D coordinates. The closest thing that works like that is the dragging system of Handles, but I don't want to use them.
Instead, I'd like to know how do they work, so I can make my own.
Does anyone know how they work? Is it built-in or it uses regular Roblox API?
