Hi You could change the polygons into polylines, add nodes along the polyline, create voronoi polygons around the added nodes and finally combine the voronoi polygons back again based on the ID of the table polygon. The more nodes you add, the more accurate the result, but you will never get 100% correct. This of course also depends on the shape of your tables (rectangular ?).
Both adding nodes and creating voronoi polygons can be done with ToolBox from RouteWare.

I have a floor space with polygons indicating the layout of tables on = the floor space. I need to calculate the gross area of each table which = is defined as follows: Net area (table surface area) PLUS the area of = half the distance from the table being calculated to neighbouring = tables. Essentially, something similar to voronoi polygons around = polygons (not points). The table layout is may not be symetric and table = sizes may vary. Any ideas of mbx's to do this, or any idea of an algorithm to determine = the neighbours and distance calculations? Quite a tall order, I know! Thanks...
