Is there a limit to the dimensions of a part's visible mesh?

[gabyalufix]

So that awesome slalom racetrack mod got me thinking: is there an upper limit to the size of parts? Could we, for example, have a part that planted a flag on the far side of kerbin? (for example, for a targeted reentry challenge), or a part that hovered over the terrain of Kerbin and marked the nations like a map, or even an orbital slolom racetrack that extended all across the planet? Or even placed a (no-clip) city somewhere far away?

I suspect there is a limit somewhere--that something somewhere along the pipeline will prevent such ridiculous parts. But I can\'t think of where . . .

For example:

Is there a distance limit beyond which parts will simply not be rendered at all? If so, is this limit linked to the 'origin' point of the part, or what? Or will the mip-mapping algorithms pixelate it to oblivion? or what?

While making that slalom course, I found that all the parts have to fit inside a 2,000 m cube with the centre at the origin. The game automatically scales down any parts larger.

So, basically a part can go 1 kilometer in any direction?

I found this out the hard way when trying to make my to-scale models of the kerbol system...

Deja Vu, This is just what I spent an hour or two doing today and found the same results. 2km sphere.
