2D CAD Data Mining Based on Spatial Relation

This paper proposes CAD data mining technique to obtain semantic elements without prior knowledge about plans being designed. The method consists of two steps. The first step is to extract frequent spatial relations between figure elements in CAD data as clues to the semantic elements. These relations are modeled as...
