Assigning IFC object type or IFC object subtype

You can assign the IFC object type or IFC object subtype when you create a component or later.

Nota: Utiliza el atributo Tipo de objeto IFC solo si lo necesitas. El Tipo de objeto IFC exporta el elemento como un BREP (modelo de superficie). Normalmente, los elementos de Allplan se asignan automáticamente a las clases IFC correctas (muros, pilares...). Si el tipo de objeto IFC asignado coincide con el tipo de elemento nativo, el programa ignorará la asignación, intentando transferir el elemento pero no como un BREP. Esto consigue que no se pierda calidad durante la exportación a IFC.

Nota: La exportación IFC transfiere los vanos en los siguientes componentes: muro (IfcWall), vigas (IfcBeam), pilar (IfcColumn), forjado (IfcSlab), cubierta (IfcRoof), cimentación (IfcFooting) y BuildingElementProxy. Si asignas un Tipo de objeto IFC diferente a un componente (por ejemplo, un IfcPlate en vez de un IfcSlab), los vanos no se transferirán.

To assign an IFC object type or IFC object subtype to a component

1. Click a tool for creating a component, such as Wall (How), open the Properties dialog box, and click Attributes....
   

   Activate Wall in one of the following ways

   • Actionbar:Rol Arquitectura Tarea Elementos Grupo de herramientas Components

   • Menu bar: Create Architecture Basic: Walls, Openings, Components

   • Keyboard: CTRL+W

   • Palette: Tools Create area in the following module(s):

   Basic: Walls, Openings, Components

   Or

   Right-click an existing component and select Modify Attributes (How) on the shortcut menu.

   

   Activa la Modificación de atributos de una de las siguientes formas:

   • Barra del menú: Modificar Módulos adicionales Atributos

   • Paleta: Funciones Modificar en los siguientes módulos:

   atributos

   Or

   Select one or more components, go to the Properties palette, click Assign new attribute in the Attributes area, and go to point 3.

2. The Define and Assign Attributes dialog box opens. Click Assign new attribute.
3. The Attribute Selection dialog box opens. Select the IFC attribute group in the Default area.
4. Go to the right column, select the IFC object type or IFC object subtype attribute, and click OK.

   This adds the IFC object type attribute with the Undefined setting to the Define and Assign Attributes dialog box.

5. Click Undefined and select an attribute value.

   The drop-down list contains the most frequently used 20 IFC object types. If the required attribute value is missing, click within the line, enter the required attribute value at the keyboard, and select Enter to confirm. The program saves the attribute value entered, presenting it again the next time you select attributes.

   Note: There is no selection list for IFC object subtype. Enter the required attribute value in capital letters at the keyboard.

6. Click OK to confirm the Define and Assign Attributes dialog box.

   The component now has the required IFC object type or IFC object subtype. This attribute will be included when you export IFC data.

Undefined / <undefined> IFC object type

You can identify the IFC object type attribute as not defined in two ways:

• After you have assigned the IFC object type attribute, it initially gets the Undefined value. The next step is to select the required attribute value in the drop-down list (right column). If the value is still Undefined, you do not know whether this value was forgotten or selected on purpose.
• Therefore, you can use Set to <undefined> on the shortcut menu of the attribute name (left column) to identify the attribute as <undefined>. This indicates that the IFC object type is still open. The model expects an IFC object type attribute, which is required by the modeler.
