I posted this question before, a week ago, in another subsection. No useful response, so I try my luck here for this simple question: https://www.anyrail.com/forum_en/index.php/topic,4055.0.html

Where in AnyRail do I find a turntable diameter 45cm?

Any brand.

There's none. Perhaps you can use the 130' turntable from Walthers? It's in the Object Libraries, Walthers structures.

That should do it.
Although a correct size would be even better.

The scale 120' (45cm) turntable is based on a real design (Diamond Scale). Is it hard to make one oneself? Or maybe have it on the AnyRail wishlist?
