The error in question is observable mainly while using the Transform tool within studio, but all other tools have this error (It’s more prominent in the Transform tool. I’m unsure as to why).
As you get further away from the origin, parts will begin to show inconsistent values for their position, rotation, and size. For instance, a part’s position may have a value of 7.999 instead of 8 on an axis, likewise with orientation and more rarely size. This is observable on all part types.
To reproduce, build a simple structure like a house out of a block floor, four walls, and two wedges for the roof. Use a 1 stud grid for this design. Drag the parts along each eachother to build, similarly to how you would if you were using the very old building toolset where you played the game to build. Near the origin it should be difficult to cause errors. Repeat this process >= 2048 studs away from the origin (if not further out), and the errors will increase in frequency proportionally to your distance from the origin.
I linked to this thread from the CSG failures thread for this reason, but I believe this relates directly to why unions fail more often when constructed away from the origin.
