An M4 PLANT 3D project, in which a plant or a company need to be planned, is managed in a database that is created by the software itself. The 3D representation is based on a database in which M4 PLANT retrieves the data of position, the type of components and the associated information and parameters from the project database in real time. Thus, plants and companies of any size can be planned and visualised in M4 PLANT . The database-supported approach also allows working in project teams with associated rights management and prevents conflicts due to simultaneous editing of a file by different users. User and rights management can be used for large projects. In addition, the database allows extremely flexible data evaluation, version management and extensive collaboration scenarios. The database structure also ensures a continuous backup of the latest planning data.
