Manually Editing Contours in Civil 3D (2007)

[rachel.harris]

I've been editing my TIN surface and it keeps giving me incorrect looking contours. Is there any way to manually draw the contours in as polylines and integrate them into the surface?

If it's giving you incorrect-looking contours, then that's because there is some problem with the underlying data used to create the surface.

You could always draw polylines in where you want contours and add them to the surface, but that might just compound the underlying problem.

If the contours do not look correct there could be something wrong with the surface data. In this case you need to fix the data.

If you are referring to contours that are not smooth but are generally in the correct location I would use Sinc's suggestion of drawing polylines at elevation in those areas and adding them to the surface.

I agree with Sinc and Jeff. When you do that, however, make sure that you don't cross any data that is already in the surface with your "digitized" contour.
