This is my attempt at curving some OO-SF B7 turnout kits.
First off I produced the start of my track plan in Templot.
Gauge > OO-SF
I started a short bit of straight plain track saved it to background, then added a left hand B7 turnout. Then curved this using normal flexure to 3400mm.
Then clicked on the [crossover] button and adjusted the track centres to 47mm (having previously in another separate session used the dummy vehicles option to work out a safe separation). This generated another left hand turnout but with contra-flexure to give me the desired croccover.
I then repeated the process but this time with right hand B7 turnouts. I added some odd bits of track on the end, then used the Transition curve link option to join the left hand and right hand turnouts.
By luck this gave me interlaced turnouts, and then I just shoved some timbers to give me the attached box file.
On the basis that the 6 foot way is a minimum and that OO-SF is already a compromise I am happy with the resultant plan.
Please feel to criticise etc
Next I will print this out, and apply some matt lacquer before gluing to some 2mm thick greyboard.
