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.

Delopments of IFC is mostly based on the work of the Open Design Alliance. ODA 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 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.


[ UNDER CONSTRUCTION ]



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.

Example BIM import ARES commander.jpg


Gstar CAD

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

IFC module is in Beta release. Separate addon


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
