Saving in the UI creates the Thumbnails folder with the preview. But 
when I use "save" (that from SdModelTestBase), the resulting file has no 
Thumbnails folder at all.

compareWithShapesDump(xDocShRef, "myFirstShapesDump", true /*bCreate*/);
verifies, that the shape is indeed contained in the loaded file. And I 
see, that the shape properties "Coordinates" and "Segments" are correct.

The error is not in the model, but in rendering.

Further observations:
I can get a
SdrObjCustomShape* pCustomShapeObj

But
basegfx::B2DPolyPolygon aLineGeometry = 
pCustomShapeObj->GetLineGeometry(true /*bBezierAllowed*/);
does not work.

The shape members mXRenderedCustomShape and  mxCustomShapeEngine are 
empty. I have tried to generate them by calling 
GetSdrObjectFromCustomShape(). It sets 
"com.sun.star.drawing.EnhancedCustomShapeEngine" as engine. But in the 
given context the servicemanager has it neither in data_.services nor in 
data_.namedImplementations.


I will now try to work in svx/qa. I can get an xShape from the file and 
now try to get a B2DPolyPolygon via CreateLineGeometry().

Kind regards
Regina
