ifc to RMEP 2012

Postby SIVC » 06 Jul 2011, 16:03

Having a terrible time trying to import an ArchiCAD IFC into RMEP 2102. Gets to a certain point then lists a heap of errors which it will not resolve and I'm left having to cancel out of the dialogue to proceed and the filecloses out. (I've checked the IFC integrity using Tekla and it looks fine.)
Any ideas? IFC mapping files available?

IFCs do not translate anywhere near as well as claimed. Most problems stem from poor modelling with in the IFC file eg, walls overlapping, extrusion with voids instead of floor slabs and beams, site topography (should not be exported), to much model detail.

You'll need to keep selecting unjoin, a dozen times or so.

Archicad have a Revit API to clean up the IFCs and get the grids to show, does anyone know if Tekla has something similar.

Best thing to do is convince them to start using Revit.

There is also a plugin designed by Graphisoft to make this IFC interoperability better.

We are using this plugin on a project where the Architect is using ArchiCAD and all other disciplines are using Revit and it definitely brings the IFC model accross a lot better than the standard Revit. Note that I said "better" and not great or fantastic. There are still some unjoining errors and walls that get projected through roofs and windows and doors that seem to fall off their wall hosts??? That said, the plugin result and the standard Revit result were vastly different and the plugin result was a lot more workable.

You can download the plugin from here: http://www.graphisoft.com/support/archi ... erability/

Hope this helps...
