Please see attached file: is there anyway i can 'cut out' some of the upper layer of my lithology model so that it correlates with the elevation map? For example, so that it looks similar to a stratigraphic model (as i cannot create a stratigraphic model as this dataset is full of lenses rather than stratigraphic units.

Yes, you can do this by using the Upper Surface Grid Filter during the creation of the Lithology model. Choose the manual option, and select the GRD model displayed in the image.

A couple of things to keep in mind:

1. Because a lithology model is a block model, the surface of the clipped model will appear somewhat blocky. Decreasing the z spacing of the solid model through the Project Dimensions will help with this some.

2. The extents and spacing of the solid model needs to match that of the grid. If your grid is extremely high resolution, you can resample it to have the same spacing and extents as those specified in the Project Dimensions through the Grid --> Math --> Resampling tool in the Utilities.

Please let us know if you have additional questions.

Best Regards,
