Problem identifying invalid geometries

I'm using FME 2013 SP1, although this problem has existing in previous versions as far back as I can remember.  This problem comes up whenever I try to translate from GeoMedia SQL Server data to any other format I've tried (AutoDesk MapGuide 6.5, ESRI Shape, ESRI file geodatabase, etc.): when reading in polygon features from several of my GeoMedia feature classes, I get the following errors:

 

 

2013-07-02 11:24:29| 99.6| 0.0|WARN |Invalid 'Polygon' geometry detected. Start and end point not identical. Forced closing the Polygon

2013-07-02 11:24:29| 99.6| 0.0|WARN |... Last line repeated 7 times ...

 

Since FME is force closing the polygons *as they are read*, I have no way of identifying them in my source data so that I can fix them.  Following the reader feature type with a GeometryValidator transformer doesn't help because the geometery issue is already fixed before it hits the transformer.

 

 

How can I go about finding these invalid polygons?

Hi,

 

 

It seems to me that you have to do it outside of FME, so in the native system.

 

Beside that it does sound like an issue of tolerance to me but since I dont know or have experience with geomedia, I could be totally wrong....

Itay,

 

 

Unforunately, the "Validate Geometry" tool in GeoMedia doesn't seem to find these polygons.  And I can't find any tolerance settings to adjust either.

Hi Carl,

 

 

And if you write these features back into geomedia via FME and reread them does the error pressist?
