The "Unable to post the new entity to the database" error will prevent exported drawings from saving if the drawing contains penetration components. For example, consider the following scenario:
1. The user has started the "Export to DWG" command in a model drawing that contains penetration components.
2. The user has specified the location where to save the exported drawing and export settings.
After the user clicks "Ok," the export process will start; however, before the operation properly finishes, the "Unable to post the new entity to the database" error will appear. The export process will be interrupted in a stage where a temporary file is opened in AutoCAD. All of the geometry in the temporary file will be properly copied from the original file and exploded, but the file won't be saved. Basically, the "Export to DWG" command will stop one step before the correct termination.
