Item Snapping

## 1. Item Snapping

Introduce intuitive snapping behaviors. These behaviors should be:

- Visually hinted (outline / highlight)
- Predictable
- Temporarily disabled with a modifier key

### **Elevation Snapping**

- Items can snap vertically to colliders of other items, aligning over the top surface of the bounding box
- Useful for stacking props or placing objects on tables, platforms, etc.

Roblox uses the bounding box of each model for this. This approach assumes that the bounding box maps to the object’s true dimensions. It needs to be easy to toggle on or off for cases when the bounding box is not accurate.

For example, a car’s bounding box is a large rectangle as high as the car’s roof. If I want to place something sitting over the trunk of the car, I will have to ignore that bounding box.
