Shapes of service Shape3DLatheObject can be created from polygons. In case this
polygon does contain duplicate points they are removed at the moment. This is
wrong as duplicate points should have an effect on the normals which are used
for shading.
Relevant code are the calls of removeDoublePoints() in 
E3dLatheObj::E3dLatheObj
E3dLatheObj::SetPolyPoly2D
and
SdrLathePrimitive3D::impCreateSlices.
A problem might be the resulting different vertical edge count. As the vertical
edge count needs to be set when using the API those cases have to be checked
carefully. Especially all the sub types of the bar and column charts (cone,
cylinder, pyramid) are affected.
