Complex object - Spatial features that cannot be represented by simple geometry, e.g. the coastline of the United States.
...
First, recent trends in the availability of analytical tools and data allow for the realistic representation of the complex objective environment for the analysis of human spatial behavior (Kwan 1997).
As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented.
In the second case the complex object has some common attributes but its parts have their own attributes too.
Distances between more complex objects (two polylines, two polygons, a polyline and a polygon) are better computed using more sophisticated algorithms that limit the number of distance calculations.
While the RDBMS manages simple data types and tables and ArcSDE technology enables communication between GIS clients and the RDBMS, additional application logic is required to implement more complex object behavior and integrity constraints.
" In GIS, these features are grouped together to form more complex objects such as "networks" of streams or roads, three-dimensional terrain "surface," and multi-polygon regions. The first four of these feature types are: ...
speedikon Architectural, all objects (walls, columns, beams, slabs, roofs, dormers, ceilings, doors, windows, stairs, ramps, components) are parametric, i.e. they can be created and manipulated by simply changing key dimensions. Complex objects, ...
