Create a Skeleton Representation Using Add > New Content

You can create a skeleton representation using Add > New Content

  1. From the Compass, click Building and Civil Assemblies.
  2. In the top bar, select Add > Content in the list (or press CTRL+N).
    The New Content panel appears.
    Note: Only the building and civil types of interest are available.
  3. Select a type.
  4. In the Object Type tab, select the Create Skeleton Representation check box.
  5. Click OK.

Create a Skeleton Representation Using Insert > 3D Shape

You can insert a skeleton representation under a building and civil object.

  1. Select the object in the tree.
  2. Select Insert > 3D Shape.
  3. In the Component Based Design expandable section, select Skeleton Representation .

Add and Edit Parameters

You can add attributes under the skeleton representation or edit them. These attributes are exposed parameters that are driven by BIM Manager specifications stored in the BuildingInformationModeling XML file.

For more information, see About Data Setup for Building and Civil Assemblies

Context: These attributes are either external parameters or standard parameters either created automatically in the skeleton representation when available or in the instantiated 3D shape for a 3D part. The figure below shows a typical example of parameters sets under a skeleton representation.

  1. In the tree, right-click a parameter of interest under the Parameters node and edit it accordingly.
    Notes:
    • The Quantity Take Off (Qto) parameters (measures applied upwards and based upon knowledge formulas) are instanced under the Parameters node.

    • A Property set (Pset) corresponds to specifications applied downwards to drive the geometry. They are instanced under the External Parameters node under the Ifc Window and Ifc Window common sections of the BIM Attributes panel.

      When you add a specification at the level of the PLM attribute, it is duplicated on the parameter. This is a downward information impacting the geometry. When the Pset drives the geometry, a dependency relationship exists between PLM attributes and derived external parameters.

      You cannot modify external parameters that are driven by the PLM attributes.

  2. click Update .
    The parameters are updated accordingly and turn green. If a parameter is modified then the PLM attribute that is linked to it is automatically updated by the knowledge rule created by the system. With a valid TER license, you can edit the knowledge rule.
  3. In the tree select another IfcDoor attribute. For example, select IfcDoor_Tag

  4. In the action bar, click BIM Attributes .
    The BIM Attributes panel appears. It lists the possible extensions that comply with the standards specified in Me > Preferences.

    The BIM Attributes panel groups attribute sets into individual expandable sections.

  5. Modify the parameter values accordingly. For example change the value of the Tag attribute under the Ifc Door section to MyTag (in yellow in the picture below).

    For more information, see Adding and Editing BIM Attributes.
  6. Click Update to account for the changes. The red thumbs turn green and the attribute value is updated in the parameter exposed in the tree
