We are still having a couple of problems since Bentley changed the ifc exporter. On the plus side, the file sizes have gone down by about 50%.
The attached screenshot shows the same model, the left side exported by SS3, the right side by SS5. As you can see, both the file structure is different, bot also the colours of the objects.
Let's focus on the colour on this thread. The one green wall on the top of the building is selected, that explains the green colour in both models. But if you have a look at the other objects, almost everything is white in SS5, regardless of if it is a wall or a slab.
Why that - and how can I change that?
Other questions: Why does it show different disciplines - SS3 shows Structural (correct), SS5 shows Architectural (wrong)?
Andreas,
Try creating another IFC without the optimizer selected. The file size will be bigger, but it may solve the issue with the color. In early testing we saw a similar thing happen with mechanical components. I did file an SR about the issue, but I do not know if it was resolved prior to the ss5 release.
Same result regarding colours without the optimizer selected.
File size is a bit bigger, but still around 40% smaller than SS3.
Problem is related to if objects exported are within a reference or not. Objects within the original file have correct colours, objects within references have wrong colours.
SR 7000148263 filed.
The reason why you see 'Structural' in the Solibri Model Viewer for files exported with Ss3 is because they specified TriForma in the header as the 'originating system', and in the Solibri 'Discipline Mapping *TriForma* is mapped to 'Structural', which is then applied to every element in the IFC file?!? In Ss5-exported files, the originating system is 'AECOsim Building Designer' and because there is no mapping for it, Solibri defaults it to 'Architectural'; hence you see 'Architectural' as the discipline of every element?!?
I have tried to convince Solibri to leave discipline 'blank' for 'AECOsim Building Designer' (or non-mapped applications), because it is a multi-discipline application; therefore, elements in the model could be 'owned' by different applications (hence we include an ObjectDiscipline property in our schema). Thus far, I have not been able to convince Solibri to change this.
Even if Solibri added AECOsim Building Designer to their mapping table the assumption that every element in the IFC model are from a single discipline is wrong.
If you agree, please contact Solibri.
We'll look into the color issue.

Great answer, Volker - though to a different thread...

This one's about colours.
