IFC import in DWG

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 plarform for engineering applications.

The results of importing IFC data after the conversion may vary per session and per software. The 3d objects become either Solids, Meshes or 'software specific entities'. For use in pratice a very important aspect of the conversion is the speed in which the specific software handles the conversion to workable DWG entities. Preferably this is done in the background. E.g. updates of other disciplines as underlay.

Both BricsCAD and Ares commander are working hard on IFC improvements. AutoCAD verticals with an older IFC processor have a hard time working with IFC files and take a huge amount of time on engineering and computer processor to convert just very simple IFC files, to the point that this made one come to the conclusion that this is just unworkable.


[ UNDER CONSTRUCTION ]



- BricsCAD BIM

Support of IFC2x3 and IFC4 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

Support of IFC2x3 and IFC4

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



- 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
