Topology

This function can be used to visualize the dependencies between model objects using the topology information within the plane panel as a basis. Given a model object both the objects defining it and the objects depending on it can be shown.

Furthermore the objects shown can be listed and activated (only plane panels). Once the plane panels are activated they can be for example, regenerated to adapt to any changes in the defining objects using the Recreate function described above.

After giving the root object, the resulting objects can be used as a new initiation. This means that the dependencies can be visualized repeatedly, level-by-level. To benefit from this function the model must be created using topological references rather than pure coordinates whenever possible.

Undo is used to back up to the previous state. for example, if a deck is initially selected and the Dependent primary is then used, Undo and then Defining will give the panels defining the initially selected deck. Undo can back up to the previous state from successive calls on for example, "Dependent primary".

Also other objects than plane panels can be picked initially, provided that they are used in the definition of a panel. This is valid for for example, shell curves and surfaces.

The topology concept is described in a separate document (see Topology in Hull Concepts).
