Modeling of Lenses
If we want to add points of soil lens into an interface, it is necessary to divide it into two lines - the upper and bottom part of lenses. The line type must be defined as "auxiliary" because this type is not displayed in the geological section drawing. Also, it is necessary to uncheck the "Creating border of areas" option because we do not want to change the shape of the generated areas - as shown in the following picture.

It is also recommended to model the lens interface behind the lens. This can be created as an "auxiliary" line, which is not displayed in the final drawing of the geological section. This line helps to clearly define the model.
