Read EXPRESS

Developers

Hi everyone,
I’m trying to parse Express file using C#.
Have you ever heard of some libraries or methods to read the information from .exp file?

I will really appreciate your concerns.
Thank You!

Best regard.

XBIM is a free to use C# library which will parse the STEP .ifc file and structure access to read and write entities.

Hi.
Yeah, xBIM is a good library to parse .ifc file.
Emmm, I want to find a method to read the information of .exp file. :thinking:

Like,

ENTITY IfcBuildingElementPart
 SUBTYPE OF (IfcElementComponent);
	PredefinedType : OPTIONAL IfcBuildingElementPartTypeEnum;
 WHERE
	CorrectPredefinedType : NOT(EXISTS(PredefinedType)) OR
(PredefinedType <> IfcBuildingElementPartTypeEnum.USERDEFINED) OR
((PredefinedType = IfcBuildingElementPartTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType));
	CorrectTypeAssigned : (SIZEOF(IsTypedBy) = 0) OR
('IFC4X3_RC3.IFCBUILDINGELEMENTPARTTYPE' IN TYPEOF(SELF\IfcObject.IsTypedBy[1].RelatingType));
END_ENTITY;

Thank You!

Best regard.

Try Peter Bonsma’s RDF IfcEngine. It can be configured by external .exp files.
