Turntable 3916 in Avery-Drexel by default is screwed up.

[JonMyrlennBailey]

This is installed in the yard at Avery in TANE Deluxe.

You have to be careful when editing near this object. If you click on your mouse near or right on this turntable in Surveyor, you may cause it to unintentionally sink deep into the ground. UNDO will NOT correct this. The turntable will not respond correctly to the Adjust Height tool either it will just keep going up in to the sky no matter what direction you drag your mouse. There seems no way to lower it.

I had this happen to me twice already. I screwed the turntable up by trying to add, move, delete, rotate and/or raise/lower objects right next to it I had to shut down Surveyor without saving and then open up the Auto-save version of what I was just working on to "fix the busted turntable" by "rolling back in time" to some extent on my edit work. Auto-save or the habit of retaining at least one earlier version of your modified route can get you out of deep trouble if things were to ever get totally botched in Surveyor. I have learned by now it is prudent to have Auto-save on its minimum interval of 15 minutes. Worst case scenario, I could lose 15 minutes worth of new edit work.

Incidentally, this same turntable seems to operate OK in Driver as long as it was not messed up by a bad edit.

A turntable is only height adjustable in surveyor/terrain/ground height up/down ... by moving the ground up, or down.

You can type that height in 0.000 increments, setting the scale, and sensitivity, and to minimum, and viewing the grid in wireframe mode, touching only the 4 inside corners of the grid square, that controls the turntable height, at the dighole.

If it ain't broke ... don't try to fix it !
