Convert the SBM into a wireframe

On the Stratigraphic tab, in the Seam Block Model group : Click Generate Horizons/Solids to generate roof and/or floor surfaces, and wireframe solid, from a layer of blocks (typically a seam).

This function "converts" a layer of blocks in the SBM into a wireframe.
