Examine reference model hierarchy and modify reference model objects

You can view 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.

hierarchy and check the hierarchy level of different objects. You can also add user-defined attributes to the reference model objects. The added attributes can be used for filtering, for example. Additionally, you can view the native reference object attributes and properties.

  1. Ensure that the Select assemblies selection switchswitch used for controlling which object types can be selected

    (for assemblies) or Select objects in assemblies selection switch (for parts) is active.
  2. Point the reference model, hold down Shift and scroll using the middle mouse button to the hierarchy level were the reference object is. Notice that if the cursor is too close to a gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces

    The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

    It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

    It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.

    , the hierarchy is not scrolled.
  3. Do any of the following:
    • To inquire the native reference object propertiesproperties associated with an object type

      Usually a single object property includes a default value that the user can modify.

      and attributes, right-click the object and select Inquire.
    • To view or modify the user-defined attributes of a reference object, double-click the object to open the reference model objectmodel object that is an individual part of an imported reference model

      The user can define user-defined attributes for a reference model object.

      The reference model objects can be moved to a model that is currently being worked on.

      Information included in a reference model object can be saved in the model database.

Tip: There are many more commands available for the selected reference model objects. Check rest of the commands on the pop-up menu.

Below is an example of a reference model representing a sanitary system. When you want to scroll the hierarchy, the selection switch Select assemblies or Select objects in assemblies must be on. The 0 level IfcProject in the example is the upmost level.

Below you can see one of the reference objects on the 3 level, IfcBuildingStorey, of the same reference model.

The last level, level 4, shows the individual parts.

In the example below, one of the reference objects on the lowest level has been inquired.
