Comment(by khermann):

 The dxfout of an 3d-polyline from AutoCAD has also the groups 10,20,30
 (xyz basepoint) in the header of the polyline element and in the vertex
 element the group 70 is set to 32 (denotes that the vertex element is a
 vertex of a 3d-curve). If the value of the 3d-flag (group 70) in the
 header of the polyline element is set to 8 or 9 (9 denotes that the 3d-
 curve is closed) indicates that the polyline element is a 3d-curve which
 is solely composed by linesegments.
