This task shows you how to instantiate a 2D component previously created on a detail sheet.

Instantiating a 2D component means re-using it (from a layout detail sheet or from a component catalog) in a layout, once or several times. When you instantiate a 2D component, you create what is known as a "2D component instance", or an "instance".

Open the 2DComponent.CATPart document. Select Start > Mechanical Design > 2D Layout for 3D Design to open the layout in the 2D window, alongside the 3D window. Make sure Sheet.1 is active.

1. From the geometry area or from the specification tree, double-click the view in which you want to instantiate the 2D component (the right view, for example). This view is now active.

2. Click Instantiate 2D Component in the Layout toolbar.
    

   Double-clicking the Instantiate 2D Component icon lets you position several 2D components on the sheet while keeping the scale and angle properties for all components.

3. From the specification tree, click the 2D component under the detail sheet Sheet.2 (Detail) item.
   
   
   
   A preview of the 2D component is displayed in the view.

4. Position the component using smartpick then click.
   The Tools Palette toolbar is displayed and proposes the following commands:

    

   Link with detail: instantiate a 2D component. The component instance is linked with its reference in a detail sheet.

   By default, this icon is activated.

   Explode: instantiate and explode a 2D component. The component instance is not linked to its reference, so behaves as independent geometry and annotations.

   Fixed together: instantiate and explode a 2D component, and apply a fixed together constraint to the geometry elements.
    

   The fix together constraint is not applied to annotations, dimensions or dress-up elements.

   Change component origin: define another point in the view.

   Change component angle: define the angle in the view.

   Flip component horizontally: rotate horizontally the 2D component instance.

   Flip component vertically: rotate vertically the 2D component instance.

   Angle: define a value for the angle.

   Scale: define a value for the scale.

5. In the Tools Palette toolbar, choose your instance type. For the purpose of this scenario, check that the Link with detail icon is activated.

6. Click the view: the 2D component instance is created.
   If needed, select the component and use the displayed manipulators to modify the component.

   Remember that if you selected Prevent direct manipulation and/or Prevent direct scaling from Tools > Options > Mechanical Design> Drafting > Annotation and Dress-up tab, you will not be able to move and/or scale the component.
