Reference models can be shown in general arrangement, assembly and cast unit drawings. For example, you may want to use 3D plant models or architectural drawings as reference models. You can select whether to show a reference model, and change the reference model appearance in the drawing view properties in an open drawing. You can select whether to show the reference model as outlines or as wireframe, set the hidden lines and own hidden lines options, and define the line color and type. Reinforcement in reference models is also shown.

1. In an open drawing, double-click the drawing view frame to open the drawing view properties.

   In GA drawings, you can also adjust the visibility settings on drawing level by double-clicking the drawing background.

2. Click Reference object in the options tree.

   The Content tab lists all the reference models included in the model.

   Note that only those reference models that have objects located the view area are shown in the list.

3. To show a reference model in the drawing, click the row of the reference model, and in the Visibility column, select Visible.
4. Go to the Appearance tab and select the representation for the reference model:

   Wireframe: Shows the reference model as a wireframe. To open drawings quickly, use the wireframe.

   Outline: The reference model is drawn in the same way as Tekla Structures native parts. It shows the reference model outline. With this option, you have the Hidden lines and Own hidden lines options available.

   Hidden lines: Shows hidden lines in of the reference model that are hidden by other reference models or parts.

   Own hidden lines: Shows the hidden lines in the reference model that are hidden by the reference model itself.

5. Modify the color and the type of Visible lines and Hidden lines.
6. Click Modify to modify the reference model in the selected view with the new settings.
