Curve Length (NA)

[Anonymous]

Hello! 

How can I enter "curve length (NA) value"?

Hi,

The easy way would be this.

Just create a profile with PVI stations at 0+00, 8+00 etc. You can roughly enter stations and make them exact using the parameter editors later.

Then add curves with length specified stations using free vertical parabola.

Once the profile is created you will realize what you have misunderstood. 🙂

Thanks

I did as you said. But I do not understand, what "curve length=(NA) value" means.

It says NA (not applicable) because there is no curve at the beginning station and the ending station.

The curves are related to the second PVI and the one before land PVI. First and last PVI have no curve information. They are part of the curves in the second PVI and the one before last PVI.

You have 3 tangents with 2 curves, I rest my case.

So what do you think NA stands for?

NOT APPLICABLE

No. The first curve is a part of the first tangent. NA really not suited here. first and last items are entities not PVIs.

What does " 250' "  value mean?  Does it mean 250 meters or 250 feet?

You have 2 things that are normally associated with feet.

The stations in feet have a + followed by 2 digits. (1+00), metric normally is follow by 3 digits 1+000.

The 250' has an apostrophe ('), normally means feet.
