The borehole status determines a relationship between original "" and "Borehole". It is not necessary to know the borehole status for generation of the geological model, but it is good to know it for better understanding of the performed modifications of the model.
The boreholes can be of three types:
Original - the "borehole" is generated from the "test profile" and it corresponds to its geological profile (which means the same soil at the same depth). The layers bellow the overall length of the test profile do not influence the borehole type. The borehole can have an arbitrary amount of soil layers with zero thickness - the type is still original.
Changed - the borehole is created from the test profile, but its geological profile was changed - by change of soil or layer thickness.
New – this borehole was created separately, it has no relationship to the tests or test profiles. This borehole can be deleted from the model.
