b) Points associated with higher objects, i.e., lines, openings or surfaces, are listed as part of
this object. Similarly, lines associated with higher objects, i.e., openings or surfaces, are
listed as part of this object. Only points that are not part of any higher object should thus
be listed under the object POINTS, and only lines that are not part of any higher object
(e.g., that do not form boundaries of surfaces) should thus be listed under the object
LINES.
c) Lines with a semicolon at the beginning are ignored as „Comments".
d) It is possible that exported Geometry once imported back into HYDRUS can have
different numbering, i.e., the project may not be identical.
e) Below is a list (KEY_WORD) of all possible objects. "POLYLINE" is a single line
defined by multiple nodes, while "LINES" is a series of lines (multiple objects). Surfaces
or Openings must be defined by a single closed curve, the type of which is given in the
name of the object (e.g. SURFACE_CIRCLE). When this rule is not fulfilled (e.g., for a
surface with complex boundary), this complex boundary will be saved as a series of lines,
i.e., SURFACE_LINES.
f) The THICKNESS_ARR3Z_NLAYERS command allows importing multiple Thickness
Vectors to define variable thickness of a Solid. On each Thickness Vector one can define
multiple z-coordinates that are used to divide a Solid automatically into Sublayers with
variable thicknesses. The number of Sublayers is arbitrary (min=1, max=100) and their
number is given by the number of columns in the file.
