Conversion from IFC to DGN is not supported yet :(

IFC

IFC or Industrial Foundation Classes is a 3D file format, used in the Architecture Engineering Construction (AEC) segment. It’s supported in the major software packages like Revit and AutoCAD by Autodesk, Tekla Structures by Tekla or SmartPlant3D by Intergraph.

The main value of the IFC is accordance to the Building Information Modeling requirements. BIM is a concept of design, construction and exploitation of the buildings prescribing creation of the large volume of the digital data around architectural objects.

This data may include not only 3D geometry, but tons of information pieces like authors, milestones and deadlines, supplier information and so on. Prior to beginning of the construction, the data base is created. It will include all the information, related to the building. Once the process kicks off the project team members will populate the data base with all the aspects of the future building.

DGN

A DGN file is a 2D/3D drawing created by MicroStation or Intergraph Interactive Graphics Design System. Such files are typically used to save designs for construction projects for highways, bridges, and buildings.
