Hi Astrid,
For the Autodesk support network, you can find links from www.autodesk.com . This page,
http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1073074, has specific technical support links.
Are you using the latest version of Map? If you need a solution soon, you might have to go with the suggested alternative.
Thanks,
Orest.

Subject: Re: [fdo-users] FDO PostGIS Provider - edit existing MULTIPOLYGON or MULTILINESTING geometries
Hello list,
are there any news concerning the possibility to edit existing
MULTIPOLYGON or MULTILINESTING geometries?
Are there any activities going on in the Autodesk support network?
It would be nice to get some information from the AutoCAD support network
or from the developer side about the possibilitiy to use MULTI-objects.
If they are not supported currently and will not be supported in the near
future we have to think about an alternative solution, i. e. implement
trigger like Mike descibed (thanks for the help) or change the type of the
geometries. But this would be quite a lot of work. It would be better if
editing on existing MULTIPOLYGON or MULTILINESTING geometries would be
possible.
Thanks for you answer.
Best regards Astrid
