ExtractContour Fail

[jpkycek]

I have a net app that extracts contours from a surface

in civil3d 2011.

The 'extract contour.method' seems to MISS OR SKIP

the  top contour of a surface when ordered.

Anybody else experience that?

I have had to write a vector workawrownd, 

Anybody else experience that?

Hi Jk,

Are you using the IAeccSurface:: ExtractContour() ? And What's the value you are passing in for the following ?

[in] double dMinElevation,
[in] double dMaxElevation,

Try giving dMaxElevation little higher than the top contour.

Thanks,
