IFCEntity, IFCType, Component mapping

Ilona C.T.

i am looking for a list indicating the mapping between IFCEntity and Solibri IFC component types.

For instance:
IfcDoor -> Door
IfcFurnishingElement -> Furniture

Is there such a list available?

Thank you in advance,
Have a great day!

Hi. I explained some of the exceptions to the usual component mapping here: https://society.solibri.com/topic/668/component-recognition/8
There is no official list available, but most can be “guessed” directly from the names.

Hi @lasse-lindqvist ,

Thank you for the quick reply!

It’s helpful to see the exceptions. I aim to summarize which IfcEntity needed for a check using certain Solibri Components in the filter.

What I don’t really understand, is how the predefined type gets defined. For example, if a Solibri Ceiling Component (IfcCovering) doesn’t have an available CEILING Predefined type (IfcCoveringTypeEnum - I guess it is based on certain collected data of the entity?), then it is actually mapped as a Solibri Covering?
So is it possible that Solibri maps a ceiling (IfcCovering) to a Solibri Covering if certain parameters are not available?

Thank you!

Dear Ilona,

do you think of something like the following? (sorry its in German):

With the following link I share the excel sheet with you. It should at least fit to the Solibri labels (Link).

Dear Stephan!

Yes, I need a list like that, including all the possible IfcEntity and Component mapping. Thank you very much for sharing it!

I am going to share the English version as soon as I get there.

Predefined type does come directly from IFC. IfcCovering has PredefinedType which is optional. In this specific case, if it is empty, IfcCovering becomes Covering in Solibri.
