Exporting Connection Code to IFC
Not version-specific
Tekla Structures
Question: I am having trouble exporting the Connection Code information to IFC file. The Connection code is not exporting to IFC even we defined it in components.
Answer: This is a common behavior because Tekla Structures do not export connections/components as separate, dedicated IFC objects (like IFCColumn, IFCBeam etc.). Therefore, connection-specific properties like CONNECTION_CODE cannot be directly attached to an independent connection object in the IFC file.
Instead, use the attribute "CONNECTION.CONNECTION_CODE". The attribute "CONNECTION.CONNECTION_CODE" writes the code into the actual object (part) that the component created. This means the connection data is transferred through the derived object and into the IFC file.
The crucial step is defining the correct IFC Entity (e.g., IfcBeam, IfcColumn, IfcPlate) in your property set definition. This selection must match the type of object the component generates:
• If the component primarily creates a column object, the include IfcColumn. For example Clip Angle (141) component creates the clip angle as a column.
• If the component creates a beam object, include IfcBeam.
• If the component creates a contour plate (like a shear plate), include IfcPlate.
Refer to the below snapshot of the IFC property set definition window for your reference.
