Example: Convert IFC objects into Tekla Structures objects in one go

In this example, you use an 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.

model as a basis for your structural modelmodel that represents a structure to be constructed

. You will convert the beams and columns into native Tekla Structures objects.

  1. Hide irrelevant IFC layers:
    1. Click the Reference Models button.
    2. In the Reference Models list, double-click the 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.

      to open the details.
    3. Open the Layers list by clicking the down arrow on the right.
    4. Hide the unnecessary layers by clicking the eye button next to the layer.

  2. Select all visible IFC objects.
  3. On the Manage tab, click Convert IFC objects.

    Tekla Structures converts the reference objects.

  4. Check the profiles and materials of the IFC objects and map missing material:
    1. On the File menu, click Settings > IFC object conversion settings.
    2. Click Check.

      Tekla Structures lists the missing profiles and materials.

    3. View the Missing Profiles and Missing Materials tabs.

      Tekla Structures lists a missing reference part material Concrete Block.

    4. Select CONCRETE_UNDEFINED from the list.

    5. Click Update Mapping Catalogs and Close.
    6. Select the Create report after conversion check box.
    7. Click OK in the IFC object conversion dialog box.
  5. On the Manage tab, click Convert IFC objects again.

    Tekla Structures converts the objects.

    The Class for all the converted objects is 992. That means that the profile of the converted object may be incorrectly rotated because there is no parametrized profile data in the IFC model.

  6. Check the conversion changes list:
    • Select objects in the changes list to highlight them in the model: Use the buttons Select objects in model view and Zoom to selected.

    • Compare the converted objects with the IFC objects.

    • Use the Inquire objects button on the ribbon to view detailed information on objects.

Below is an image of converted beams and columns.
