Dear Brisket,
You are correct when you set the sep file to reflect parabolic, but you also need to account for it when you ues the calculate super tool. You'll select the sep file, but also set the Transition ID to one of the parabolic options as illustrated below.
If the SEP file is set to parabolic, then the following options are supported:
Parabolic reverse curve – This symmetrical option utilizes the parabolic transition with no tangent and the length of each parabola is one-half the transition length.
Parabolic Reverse Nonsymmetrical Curve 1 - Lengths of the two parabolas are specified: Sag parabolic Length (L1) =45 and Crest Parabolic Length (L2) = 55. The Tangent Length = Transition Length - (L1+L2) as depicted below.
Parabolic Reverse Nonsymmetrical Curve 2 - Lengths of the two parabolas are specified: Sag parabolic Length (L1) =30 and Crest Parabolic Length (L2) = 40. The Tangent Length = Transition Length - (L1+L2) as depicted above.
The values of the parabolic lengths are set by configuration variables by default (but are not displayed in the configuration dialog). To change the values, add the configuration variable and the desired values:
CIVIL_SUPER_REVERSE_PARABOLIC_NONSYMMETRICAL_1_SAG = 45
CIVIL_SUPER_REVERSE_PARABOLIC_NONSYMMETRICAL_1_CREST = 55
CIVIL_SUPER_REVERSE_PARABOLIC_NONSYMMETRICAL_2_SAG = 30
CIVIL_SUPER_REVERSE_PARABOLIC_NONSYMMETRICAL_2_CREST = 40
