Circle radius

[Hoiiip]

I'm trying to draw a 90' turntable in HO scale. like Walthers 933-2860.  I can add a circle but I don't know what radius to enter for a 90' turntable.  I tried 45 but it was huge.

Well, you will have to divide the 90' by 2 to get the radius,but also by the scale : 1:87.
That will result in about 6.2", or 15.75cm.

You'll find some of the Walthers turntables in Track libraries/H0/Walthers/Turntable
