then you need to go to the top left of your Unity window and where it says, "Center" click it and change to "Pivot". You may also need to delete a model you duplicated and re-transform it if you had already attempted moving it while it was incorrectly snapping. (Also, the global button switches between global and local transform space, just like Blender).
