                  I'm so sorry for all time you spent with my problem,
                  but now I see: We talk at cross. It's my fault, I
                  didn't explained correctly what I need.<br>
                  I want to receive a *filled* volume mesh.<br>
                  I created 2 files (steffen.stl and steffen2.stl) with
                  my python script.<br>
                  With steffen.stl I successfully could create such a
                  filled volume mesh as seen in steffen.msh.<br>
                  When I try exactly the same with steffen2.stl then I
                  get the error message in the subject (and the surface
                  mesh doesn't get filled).<br>
                  So that's why the .iges file you sent me isn't what I
                  need.<br>
                  <br>
                  Sorry for all this confusion,<br>

                    I did a volume based on your surface mesh - see
                    attached IGES (compressed with 7-zip).<br>
                    After reading it into GMSH, you can create the 1D,
                    then 2D and finally 3D mesh with no errors.<br>
                    <br>
                    You can do the same using GMSH volume definition (as
                    already wrote)-> it will work, as the fundamental
                    faces are plane triangles.<br>

                                <br>
                                No it is more clear. If you are working
                                with cloud of point, then you may use
                                Meshlab for surface regeneration. There
                                are many software that are able to
                                handle in a resonable way the cloud of
                                points (like rhino3D + resurf, other).
                                But these are rather commercial.<br>
                                <br>
                                From the other side - try to do the
                                simplest thing:<br>
                                <br>
                                Adjust your python script for surface
                                creation in order to save not as PLY but
                                as GMSH "geo" file using points and
                                lines<br>
                                <br>
                                Point(1)={0,0,0} ;<br>
                                Point(2)={0,1,0} ;<br>
                                ...<br>
                                <br>
                                Line(1) = {1,2};<br>
                                ..<br>
                                and.. Line Loop & Surface ->
                                Volume ..<br>
                                <br>
                                Then you will get a volume defined by
                                geometric entities. In this case is
                                shoul be easier to create a better mesh
                                on surface and then on whole volume.<br>

                                  I also checked my surface mesh for
                                  double vertexes but I didn't find any.
                                  What do you mean with "double egdes"?
                                  Isn't there always a "double edge",
                                  because two neighbour facets always
                                  have one same edge?!<br>
