IFC can be used in several DWG based software products to transfer design data. It will contain only data for 3D for modelspace use. Paperspace information like annotations and dimensions are best transferred additional as sperately DWG's. 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 a workable solutions. Preferably this is done in the background. Like updating models of other disciplines as underlay for design in progres.

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 DWG. Of course, the Autodesk AutoCAD verticals have an import function as well.


BricsCAD BIM

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).

Fast and reliable import and Export

IFC will be turned into mainly Solids (ACIS) with a variety of metadata

IMPORT OPTIONS

EXPORT OPTIONS

EXPORT BASE QUANTITIES

IMPORT PARAMETRIC COMPONENTS ETC

Example BIM import BricsCAD.jpg



Ares Commander


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.

Fast and reliable import and Export

IFC will become "BIM entities" in the software

BIMDEBUG options: RVT support

-BIMMOVE,

-IMPORT OPTIONS

-NO IFC EXPORT

-FILTERS etc.

Gstar CAD

IFC module is still in heavily in Beta mode. GstarCAD 2019 should be able to support IFC2x3 and IFC 4 REsults may differ, at least it gives results fast! 3D perspective seem not to work (?)

Example BIM import GstarCAD

Example BIM import GstarCAD.jpg


AutoCAD Architecure & AutoCAD Civil3D

- Have the same API or 'engine'

- A Very very hard and slow import and export!

IFC2x3, from 2020 IFC4 is support (?!)

IFC hierarchy comes in over several DWG files XREFs


Import proces is slow coding to AutoCAD
