 \section{Combining a 2D subsoil profile with a surface line geometry}
 To create a calculation profile, another option is by combining a 2D subsoil profile with a surface line geometry.
 
-If the surface line geometry lies entirely below the 2D subsoil profile, no combination can be made. 
-A calculation cannot be made for this situation, and an error message will follow. 
+If the surface line geometry lies entirely to the left or to the right of the 2D subsoil profile, a combination cannot be made. 
+If the surface line geometry lies even partially below the 2D subsoil profile, no combination can be made. 
+In both cases, a calculation cannot be made for this situation, and an error message will follow. 
 This error message will not interrupt the entire DAM process; the message will be recorded in the log file.
 
 For merging a surface line geometry with a 2D subsoil profile, the surface line geometry is leading. 
 This determines the left boundary (X-coordinate of the first point in the surface line geometry) of the 2D calculation profile to be created. 
 It also determines its right boundary (X-coordinate of the last point in the surface line geometry).
 
+The process consists of: 
+\begin{itemize} 
+	\item Check that the 2D subsoil profile is not null
+	\item Check that the filling material and the surface line geometry are defined properly.
+	\item Check that the surface line geometry lies completely above the bottom of the 2D subsoil geometry.
+	\item Make a complete copy (clone) of both the 2D subsoil profile and the surface line geometry to prevent the original data from being changed. 
+	\item Then perform all subsequent steps on the copies. 
+	\item Round all coordinates from both the 2D subsoil profile as well as from the surface line geometry.
+	\item If necessary, adapt all X-coordinates from the 2D subsoil profile with the specified shift. 
+	\item As the original profile may hev been shifted, create an extra clone (clone2) of the cloned profile to be used later to reset/retrieve surface information. 
+	\item Create a new 2D profile as place holder for the resulting calculation profile.
+	 
+	\item Add the 2D geometry to the 2D profile. 
+	\item Finally, add all 2D layers (surfaces with info) to the 2D profile. 
+\end{itemize}
