GDI Imort creates wrong type of a parcel with an inner parcels


Hi,

we have a serious problem with the GDI Export and Import. We use the Import tool, to fill in the DGN from an Oracle Database. It seems that parcels with holes are imported not in the right way. Unfortunately these cases appear frequently in our cadastre project. I can reproduce this behaviour interactively with Bentley Map:

When I create a parcel with an inner parcel interactively, I get a grouped hole. When the import process creates exactly the same parcel, I get a parcel of type Polygon Collection.

This happens in a cadastre wizard created project, all options answered by default.

Here is the description, what I'm doing in the video. If it is too small use strg + scroll the mouse:

- I'm using the latest version of Microstation and Bentley Map actually available from Bentley download.
- I've created a parcel with an inner parcel interactively.
- I turn on labelling in the map manager for the parcel (Area).
- The area label is shown in the right way for the outer and the inner parcels.
- The parcel I created is of type grouped hole.
- I export the parcels in a GML file.
- For the following import process, I delete the Parcels. I delete them, deleting the three boundaries. While I delete them, the parcels are deleted by the syncronizer.
- Now I import the deleted Parcels back from the GML file, expecting to get the same data set as before.
- Unfortunately labelling is not ok. anymore: The holes now show two labels, their own area and additionally the area of the outer parcel on top of it.
- Looking at the element type: It now has changed from a grouped hole to a Polygon Collection.
- When I try to delete the data set, it is possible to delete the three boundaries, but the syncronizer can't delete the associated parcels. They still stay in the DGN.

Looking at the created GML file attached to this post, I can't see a problem. The outer parcel has three boundaries, one exterior and two interior linear rings. (I had to attach .txt extension to the file because *.gml is not allowed for upload)

Please help!

Tom
