Missing Type Enumeration in Solibri 9.12

agroni

Hi,
am I missing something here or did the Type Enumeration of IFC Entities just disappear?

In this IFC File I have an IfcSlab Type FLOOR. The Type is not displayed anymore, respectively cannot be defined in the RuleSet.
Is it not anymore supported?

Oh Boy!!!
The Predifined Type was always there:

Hi. The Predefined Type (Vordefinierter Typ) here seems to show FLOOR in this example.

Generally Predefined type for components comes from the corresponding IFC Type enum. For Slabs specifically it is the IfcSlabTypeEnum.
And it is good to remember that, in case IfcSlabTypeEnum happens to be ROOF, the component is actually imported as Roof in Solibri, not Slab. This weirdness has been implemented to support modeling workflows that have been modeling roofs as slabs with this type set.

IfcType field usually comes from the related IfcTypeObject instance, which in this case is IfcSlabType.

9.10.6 had some changes to the IFC type showing: https://www.solibri.com/news/solibri-9-10-6-release-notes

Hi, I would like to ask how to determine the value of the predefined type for IfcSlabTypeEnum, as it is specified in the IFC file.

getIfcEntityType() returns SLAB instead of FLOOR, similar to the example above.

Unfortunately there is not the same possibility for slab as there is for covering:

if (component instanceof Covering) 
{
   Covering covering = (Covering) component;
   Covering.Type type = covering.getType();
   CompIfcType_String = type.toString(); 
}

Best regards, Reinhard

This should be just added to the API, but hasn’t been done as of yet.

It might be available via

slab.getRelated(Relation.of(Relation.Type.DEFINES_BY_TYPE, Relation.Direction.FORWARD)

or

slab.getRelated(Relation.of(Relation.Type.DEFINES_BY_TYPE, Relation.Direction.BACKWARD)

and study the Type object it finds (untested code),
but the intention is to add the simple getter methods.

Thanks for your answer, but this way I only get UNKNOWN as Type of the Related, but the Slab is definitely FLOOR in Solibri interface and SLAB in API -> component.getComponentType()

May you have one more hint for me, thanx a lot so far

Reinhard

Collection<Component> CT = component.getRelated(Relation.of(Relation.Type.DEFINES_BY_TYPE, Relation.Direction.BACKWARD));
	
if (CT.iterator().hasNext()==true)
{	 
	String CTYPE = CT.iterator().next().getComponentType().toString();
}
