Listers, I would like to be able to buffer an object and to have the buffer 'clip' to known obstacles or hazards i.e.. if a point location was buffered to 3 miles but an obstacle or hazard, a main road or railway perhaps, fell within that radius the buffer would not go beyond it. The obstacles would be in a separate table to the buffered object, the buffer created in the cosmetic layer, the obstacles or hazards would be polylines not points. Anyone got any ideas? Will summarise ideas and post back.
