Moving the Components of a Sub-Product in the Parent Product

This task illustrates how to move a component belonging to a rigid structure (the Parent Product is rigid). It implies that the instance of its parent product's reference is moved.
Open the Articulation.CATProduct document.
The product "Articulation" includes one CATProduct and two CATPart documents (in rigid mode) as follows:

  1. Edit or double-click Articulation to make it UI Active (User Interface Active, in blue color).

  2. Select link.1 and move it with the compass:

The compass is not positioned on link.1 because the component is rigid and this is its instance within the product, Chain.1, which is taken into account.

  1. As a result, you cannot move link.1 independently from link.2. The whole assembly (Chain.1) moves because its sub-components (link.1 and link.2) are rigid.

  2. Undo this action to return to the initial state.

  3. Edit or double-click Chain.1 to make it UI Active (in blue color) in order to be able to move the instance of the link.1 reference.

  1. Select link.1 and and move it with the compass: Note that if chain (chain.1) is UI-Active , you cannot move chain from Articulation. You can move the "sons" of the UI-Active object and not the object itself (the UI-Active "father"). You cannot move an object with respect to itself.

Note that in this case, the compass is positioned on link.1.

  1. You can now move link (link.1) independently from link (link.2).

If you double-click link (link.1), it becomes highlighted in blue (UI-Active) and you will not be able to move its "father".

Therefore, to move a sub-product in a rigid structure, you need to edit its parent product.
