Background

When creating the hull model in Hull Modelling there is a general ambition to use topological references to as large an extent as possible. This ensures that changes in one object will more or less automatically propagate also to the dependent objects. Another way of expressing this is that the use of explicitly given coordinates and positions should be minimized.

One means of enhancing the level of topological references in the modelling work is to use the so called topology points that are available in the design language of Hull Modelling. The concept topology point and its intended use in Planar Hull Modelling are outlined in this chapter.
