IFC can be used in several DWG based software solutions to transfer data. It will only contain data 3D for modelspace use. Paperspace information like annotations and dimensions are best transferred as additional DWG's sperately from Revit, ArchiCAD, Tekla to name a few.

IFC can be used in several [[Drawing_(DWG)|DWG]] based software products to transfer design data. It will contain only data for 3D modelspace use. Paperspace information like annotations and dimensions are best transferred additionally as separate DWGs. Development of DWG-based IFC is mostly based on the work of the Open Design Alliance (ODA). This is a non-profit technology consortium that provides software solutions as platform for engineering applications. Which is main domain for DWG use.

The results of importing IFC may vary per ifc file and per software. 3d objects become either Solids, Meshes or 'software specific entities'. For use in practice the speed of the conversion is a very important aspect to have workable solutions. Preferably this is done in the background. Like updating models of other disciplines as underlay for design in progress.

These days a couple of software vendors are working hard to improve their capabilities for handling IFC2x3 and IFC4. BricsCAD, Ares commander and GstarCAD are upcoming names in the DWG ecosystem. Of course, the Autodesk AutoCAD verticals have an import function as well.

The results of importing IFC after the conversion may vary per ifc file and per software. The 3d objects become either Solids, Meshes or 'software specific entities'. For use in pratice a very important aspect is the speed in which the specific software handles the conversion to workable DWG entities. Preferably this is done in the background. Not to bother work in progress. Updates of other disciplines as underlay.

Both BricsCAD and Ares commander are working hard on imptovements of BIM and IFC capabilities. AutoCAD verticals with an older 'IFC processor' have a hard time working with IFC and take a huge amount of time and computer processor resource to convert just the most simple IFC files, to the point that this made one come to the conclusion that this is just unworkable. But in theory it works.

BricsCAD BIM supports IFC2x3 and IFC4 for import and export. It is certified for IFC 2X3 coordination view 2.0. The IFC standard includes both parametric and non-parametric shapes, material definitions, metadata in the BIM file, and property sets (PSets).

The BIM Navigator palette enables you to import and view one or multiple BIM files. Supported formats include IFC (versions 2X3, 4 and 4×2), as well as RVT ([[Revit]] versions 2011 through 2020). You can further use the filters to show/hide only the objects you need, combining criteria such as the discipline, category, floor, class, or other BIM properties.

GstarCAD 2019 which supports IFC format that provides interoperability between different software applications. Through the support of data import and export, big and complex BIM models can be imported and handled in GstarCAD 2019 and GstarCAD Architecture 2019 now
−
GstarCAD 2020 should be able to handle IFC2x3 and IFC4

Results may differ, conversion is fast.

- IFC2x3, from version 2020 it should be able to handle IFC4 support (No increase in speed ?!)

- Hierarchy comes in over several DWG files XREFs, a clumsy way
