Generate Contour from Grid

[Gene]

Hi all,

After a 3D Stratigraphy Model has been generated, I want to form a contour map of a certain strata (e.g. a rockhead contour).

I used Stratigraphy/Structural Elevations/2D and selected the top layer of the strata.

A contour map was formed, however, the result does not take the ground surface in consideration.

Strata does not truncate above the ground surface.

How can I fix the problem?

Thanks

Hi Tom B

Thanks for answering.

But seems you misunderstood my question.

I have chosen "Constrain Model Based On Ground Surface" when I generate the Stratigraphy Model.

After that, I want to generate a rockhead contour base on the generated model. (using Stratigraphy/Structural Elevations/2D )

However, the contour generated shows the rockhead above ground level, which is not true.

Seems the contour does not "Constrain Model Based On Ground Surface"

How to tackle this problem in this case?

Thanks
