As a builder who primarily builds in-house using Studio, I find it annoying to have to slightly move my mouse to align two parts together, if the increments were not .125 or .25, it is often difficult to get a precise alignment without having to redo an entire build.
In Blender they give you the ability to instantly place your object on the edge or vertex of another object when in close proximity.
The Request: The ability to snap parts together via their edges regardless of the increments used to scale the parts.
