Hi there, i am witnessing what seems like a stand still of certain DWG based software when it comes to speed on processing ifc. The conversion process to have data available takes forever. What specific demands are being formulated for the certification of new ifc4. @jwouellette can you guide me wit…

Ouch! That is a serious weakness in the certification. How fast is fast enough? Well, that is a question that needs be addressed by Buildingsmart and the user base. At least NOT 2 hours for just a very simple building. You know what the say about time, right? It IS money. Even with a new IFC4 certif…

I have to agree with you @Hans_Lammerts , that the processing of IFC Data in different Software is a crucial task. I think we all have this experience of… time is money :slight_smile: But isn‘t that what makes competition in the market grow? Some software process data faster and others slower. That…

Hi @agron , Firms BUY! (for quite some money…) software and the certification suppose to say something for the ability to use it in a reasonable matter. A minimum is needed. The argument that the laws of the free market will regulate or somehow correct this flaw is, in my opinion, not valid. It needs…

As i see it, the only other alternative to get around is is to skip all sofware vendors and go for open source. Build your own car. why not? this is also an option that the market does not prohibit. In my experience, there are some already good open source solutions that can handle better the IF…

There are a number of issues with certifying performance. Certification tests are generally small. Performance on them wouldn’t say much about larger projects. Performance may vary wildly on type of data instead of size of file. For example, a small file with 10000 BReps may perform much worse t…

Fidelity… based on a design coordination workflow for IFC2x3 (thus the “Coordination View” MVD), as well as design coordination and other workflows that might benefit from a “Reference View” for IFC4. Speed means nothing if the results aren’t reliable across the board. Fidelity was, and still is, a…

Acceptance = fidelity × speed . The value of all this metadata means nothing if it takes 10 minutes to get the most simple geometric shape across. This formula can be used over 3D CAD versus ‘BIM’ in general.

One file from the GEOBIM 2019 benchmark is very interesting to use and benchmark speed on import: Uptown.ifc filesize : 240 mB More information about the backgrounds of this file : UpTown IFC model " Note: The use of semantic entities is not perfect. For Example, many IfcBuildingElementProxy desc…

This raises some more concerns at my end. [image001(1)]

May i ask what official goals certification has? And i mean that seriously, without any undertone intended.
