Measurements for an O-22 switch

[Anonymous]

where does atlas measure for their radius?  I know Lionel measures from outside edge to outside edge, does atlas measure from the center rail?

thanks, for some reason those measurements aren't working out right.  I'll keep tinkering with it.

Straight is the same as a section of O-31 straight, turnout is the same as a section of O-31 curved.

Hello, I'm trying to put together a track layout with the Atlas freebie software and I've had to create the O-31 turns that I'm using with the flex track, but I don't know the measurements for the O-22 switch, length of turn, degree of turn, and length of the straight portion.  Can anyone help?

Thanx in advance.
