Problem with automatic creation/deletion of interfaces

In ATENA 3.3.1 and older, interfaces were sometimes deleted or not created when a macroelement was added/copied or deleted in Atena 3D, or not deleted when a macroelement was moved.
This is fixed in version 3.3.2, please upgrade. Users of version 3.3.0 and newer with a valid maintenance agreement can download the upgrade online in the downloads section.
With old data, application of the corrected contact checking agorithm has to be triggered by adding and deleting a macroelement.
