IFC insert

You can insert IFCfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

models as reference models to Tekla Structures , and optionally convert the inserted IFC objects into native Tekla Structures objects directly by using the direct conversion, or selected IFC reference objects using conversion change management. You can use inserted IFC reference models, for example, in clash checking, reporting and scheduling.

Insert a reference modelmodel which the designer can use as an aid when building another model

A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.

  1. Open a Tekla Structures model where you want to insert the IFC reference model.

  2. Open the Reference Models list by clicking the Reference Models button in the side pane.

  3. Click the following link and follow the instructions for inserting the reference model: Insert a reference model.

Supported IFC schemas and IFC applications

  • Tekla Structures supports the following IFC schemas:

    • IFC2X3 (recommended)

    • IFC4

  • For a list of applications/utilities that are purported, by their developers, to provide IFC insert and/or export functionality, see List of all IFC applications.


  • The IFC insert IFC2X3 functionality has the IFC certification granted by buildingSMART international. For a list of IFC-certified applications, see Certified Software.

Supported entities

The IFC reference model insert in Tekla Structures supports all the sub-objects of the IfcBuildingElement classpart property that groups parts according to identifiers given by the user

The identifiers of classes are usually numbers. Classes can be used for defining the color of parts in the model, for example. Class does not influence the numbering of model objects.

and sub-objects of the IfcProduct class including:

  • Architectural entities

  • Structural entities

  • Building services entities

Supported formats

  • IFC ( .ifc ) and ifcXML ( .ifcXML ) formats are supported.

  • You can use compressed ( .ifcZIP ) or uncompressed insert files.

  • IFC4 does not support ifcXML.
