Is this any good? You didn't say how far round the curve you wanted to go on the right, so this is just my guess: 2_191229_460000000.png 2_191229_470000001.png Box file below. Manually create a transition having the required radii change over a suitable length. Add a slew that starts and ends just outside the transition zone. Peg it onto the outer curve on the right. Adjust the slew amount (CTRL+ F7) until it is nicely over the bottom template at the end of the slewing zone. Put the peg on the end of the slewing zone position. Make split at peg to leave a short bit of plain curve. Cancel the slew in it. Recreate the ...
