Hi all, IfcOwnerHistory defines all history and identification related information. In order to provide fast access it is directly attached to all independent objects, relationships and properties. IfcOwnerHistory is used to identify the creating and owning application and user for the associated…

I like what I see in “Advanced (Level 3)” and for sure the industry is following this when bSI is thinking to develop OpenCDE which is API-based However, I think bSI is improving IFC to be suitable for ISO 19650 which CDE is an important part of it But till now I haven’t seen any evidence about If…

Could you please explain what you mean with "… haven’t seen any deviance about IfcOwnerHistory improvement … " ?

Thanks, I mean evidence In IDM Tookit project I saw a lot of good improvements which I think are good for the start and during the time bSI can improve it But I don’t know is it an open source project or not? It would be part of IfcDoc or OpenCDE or not?

First, as an owner a change log is definitely of interest. But from my perspective, it is the responsibility of the building owner to keep his own change log. For this purpose, the last change coming with an IFC file is sufficient to log into the owners system. That way, the owner can easily maintai…

I have something in mind that needs all change logs But yes, we can implement these change logs out of IFC and just share the start and the last log Imagine you design and after a while you realize that you did wrong and your client wanted you did it in another way. What you do? You have to start …

“Imagine you design and after a while you realize that you did wrong and your client wanted you did it in another way.” It is fairly common, facing the outcome of formal written demands and finally seeing the result as 3d model. The visual model or even drawing is a form of communication. ‘Seeing i…

For the design proces a change log would not be be part of the ifc. It will make 3d modelling unnecessary complex. And personally i find it not logical to put it in any form of 3d model. Not during operation phase either. Theory versus pratice. (?)

I think 2-3 people know what am I want and what am I going to build which is not as same as what’s happening in the projects today If I spend my time in something, I want it be more advanced than what’s “general” in the industry I tried give a simple example to show a small part of a “Design Syste…

I would consider change log for administration purposes. Like putting up the bill of manhours or gibr management an overvoew. BUT NOT for making the design better or definite. @Hans_Lammerts You mentioned change log for administration purposes, so let’s accept this which is true. So, do you thin…
