ElevationAt method along asym vc

[Anonymous]

The ElevationAt method for aeccprofiles seems to be giving incorrect
elevations along an aysmmetric vertical curve.

Thanks,

Drew,

Hoping for more detail... what is the configuration of the curve (sag,
crest, grade in/out and lengths 1 & 2) ? Also, what formulas/calculations
are you using to verify the elevations?

thanks in advance,
Mike

Michael:

The configuration doesn't really matter. I got inaccurate elevations for the
following 3 configurations:
crest, 75', 100', 1.76%, -1.55%
sag, 150', 125', -1.55%, 0.61%
crest, 200', 100', 0.61%, -0.84%

I compared the ElevationAt values with the low point and high point
elevations listed in Profiles => Edit Profile... => Select PVI. They don't
match. So either one or both is/are wrong. My guess is that the listed
elevation under Select PVI is correct. The HighPointElevation and
LowPointElevation property for the asym vc also seems to list the correct
value.

Unrelated, the begin and end station properties for the asym vc are also
listing incorrectly.

I can send you a drawing and code if you like.

Sincerely,

Drew,
Much thanks - seems simple to check from your reply, I'll verify and write
to you directly if I have any questions.
