... likely to have been re-drawn using the "standard crossing angles" method (with equal K-crossings), so I set the angles to C-9 CLM V 1:8 CLM K 1:6 CLM K 1:6 CLM V 1:5 CLM and the result matches the original 1927 map quite well. cheers, Martin. posted: 16 Sep 2020 18:29 from: Martin Wynne Hi Derek, Your question has prompted me to add an additional option to the new find intersection function: 2_161318_480000000.png This will not only find an intersection, but adjust the curving radius in the control template until the intersect is at a specified angle. This will be useful for tracks crossing the interval where the V-crossing angles are known. It will be a help when making ladders across transition curves and suchlike. In the past I have adjusted the curve by eye zoomed-in, which works fine, but an actual calculation is more elegant. It is likely to be very slow sometimes, so don't tick that box by ...
