Change the color and transparency of model objects by using object representation

Change the color and transparency of model objects by using object representation

Use object representationrepresentation of a model object or an object group in a model view that is based on the color and transparency settings applied to the model object or the object group

to set the color and transparency of model objects in model views and to create customized presentations of the model by using defined object groups.

With object representationthe way that the information included in a model is represented visually

settings and object groups you can define that, for example, only some model objects are visible or that some model objects are of certain color.

To open the object representation settings, on the View tab, click Representation. The Object Representation dialog box opens.

Note that changing the settings in the Object Representation box affects all model views.

The following images show the same model with different transparency settings:

  1. Standard color and transparency settings

  2. Only parts whose profile name starts with IPE* or HEA* are visible

  3. Parts whose user-defined attributeobject property created by the user in order to widen the range of predefined object properties

    User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

    Planned erection date is set to a certain date are displayed in blue, while all other parts are 90% transparent

Use the Class property to change the color of parts and reinforcement

Use the object representation settings Color by class and Visible to enable the changing of the color of parts and reinforcement in the part and reinforcement properties.

  1. To open the object representation settings, on the View tab, click Representation. The Object Representation dialog box opens.
  2. In the dialog box, ensure that
    • Object group is set to All

    • Color is set to Color by class

    • Transparency is set to Visible

    With these settings, all parts and reinforcement are colored according to their Class property in the part and reinforcement properties.

    The possible 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.

    numbers range between 0 and 14, and result in different colors as follows:

    Class numbers above 14 produce the same colors as 1...14. For example, class numbers 2, 16, 30, 44, and so on, all result in red.

  3. To change the part or reinforcement color in the part or reinforcement properties:
    1. In the property panecontrol element in Tekla Structures user interface in the form of a side pane window

      The property pane can be used to show and modify the properties of model objects.

      The property pane can be customized by using the property pane editor.

      , in the Class box, select a new class.
    2. Click Modify.

    Alternatively, you can change the Class property on the contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

    The user can customize the contextual toolbar.

    .

Note:

You can also use class numbers to define the default color of pour objects and pour breaks.

Define color and transparency settings for object groups

  1. On the View tab, click Representation to open the Object Representation dialog box.

    The settings Color by class and Visible are on by default.

  2. To define the color and visibility of a selected object groupmodel objects whose settings match the settings that the user has defined for a certain purpose

    In Tekla Structures, an object group is defined by rules and conditions, for example, to control the transparency and coloring of model objects in the views. Object groups can also be used in filtering tools, for example in selection filter, to select all objects that match certain properties.

    , click Add row.
  3. Select an object group from the Object group list.
  4. Use the Color list to define the color for the objects in the object group.
  5. Use the Transparency list to define the transparency for the objects in the object group.
  6. Repeat steps 3–5 for each row you add.
  7. Use the Move up and Move down buttons to change the order of the rows.

    The reading order of the rows is from bottom to upwards. If an object belongs to several groups, the upmost row defines the color and transparency setting defined for the objects.

  8. Enter a unique name in the box next to the Save as button.
  9. Click Save as to save the settings.
Note:

If your setting does not contain the group All, Tekla Structures adds that row to the bottom of the list when you click Modify, Apply or OK.

Color settings in object representation

Option Description

As is

The current color is used.

If the object belongs to one of the object groups defined in the following rows, its color is defined by the settings that the object group in question has on that row.

Colors

Select color from the list.

Color by class

All parts are colored according to their Class property.

Color by lot

Parts belonging to different lots or phases get different colors according to the lot or phase number:

Color by phase

Color by analysis type

Displays parts according to the member analysis class.

Color by analysis utility check

Displays parts according to the utilization ratio in analysis.

Color by attribute

Displays parts in different colors according to the values of a user-defined attribute.

Transparency settings in object representation

Option Description

As is

The current visibility.

If the object belongs to any object group whose visibility and color settings have been defined, the settings will be read from that object group.

Visible

Object is shown in the views.

50% transparent

Object is transparent in the views.

70% transparent

90% transparent

Hidden

Object is not shown in the views.

Define your own colors for object groups in object representation

If the color properties are not sufficient, you can define your own colors.

  1. On the View tab, click Representation to open the Object Representation dialog box.
  2. Select an object group from the Object group list.
  3. In the Color list, select Choose color....
  4. Do one of the following:
    • Click a color in the Basic colors palette.

    • Click Define Custom Colors and create a color of your own:

      1. Click a color in the color window.

      2. Define the color depth by using the color bar on the right, or enter the exact RGB values.

      3. Click Add to Custom Colors.

      4. Click the color in the Custom colors palette to select it.

  5. Click OK.
  6. Click Save to save the changes.

    When you open the Object Representation dialog box the next time, the Color list shows a maximum of 10 colors that you last defined. Customized colors are shown above the dashed line:

Information about the colors that you define for the object groups is stored in the used_custom_colors.clr file, which is located in the current modelmodel that is active in Tekla Structures

The current model can be a single-user model, a shared model or a working model.

's \attributes folder.

Information about the colors that you add in the Custom colors palette is stored in the xs_user.xxx file in the model folderfolder that is used for storing files associated with a model

Tekla Structures stores all files associated with a model in a folder it creates with the same name as the model database (.db1).

In multi-user mode all users access the same model folder.

(xxx is your user name).

Copy object representation settings to another model

  1. Select the settings you want to copy.

    The settings you have created are located in the current model’s \attributes folder, and they have the file name extension .rep.

  2. Select where you want to copy the settings.
    • To make the settings available in another model, copy them to the \attributes folder of the destination model.

    • To make the settings available in all models, copy them to the project or firm folderfolder that is used for storing Tekla Structures-related files customized for a particular organization

      A Tekla Structures user can, for example, customize a company’s cloning templates and save them in a sub-folder located under the firm folder. After this, the customized cloning templates can be used in all projects carried out for the company.

      , defined by the advanced option XS_​PROJECT or XS_​FIRM.

  3. Restart Tekla Structures.

If you want to delete the settings in the \attributes folder, select the .rep file and press Delete.
