[fdo-users] OGR provider 3.4, AutoCAD Map 2010 and ESRI personal geodatabase

[Traian Stanev]

Hi,

It means that there is likely a feature with a null geometry value in the table or with a geometry that is not supported by the OGR/PGDB provider (3D, arcs, etc). In such cases the OGR provider throws an FDO exception with the message "Geometry is null.". It seems like Map cancels caching of the remainder of the layer once it encounters that.

The way to check if indeed there is such null geometry would be to bring up the data table for the SHP layer and see if there are really 6 features or there are more with some null geometry.

Greetings,

We have been experimenting with the OGR provider for AutoCAD Map 2010 and have found something we can't explain.  From ESRI ArcMap we export the same feature set as a shapefile, as a cad file and as a personal geodatabase.  Then in AutoCAD, we open the cad file, use the SHP provider to attach the shapefile and the OGR provider (v 3.4) to attach the personal geodatabase.  Theoretically, we should see 3 instances of each feature in one form or another  . . . right? 

No.  When we attach to the personal geodatabase and add our feature to the map we get  get the message "failed to cache features" and "geometry is null".  In this particular test set, are 6 features which should have appeared but only 4 did.  The table data does include records for all 6.   

The shapefile and cad file show the features as they should. 

Any ideas what causes the two error messages and two features to be missing? 

Thanks,
