The Assembly Structure Information Model of Part Engineering Drawing
The assembly structure information model of part engineering drawing is proposed in this paper. By using extended entity data, the geometric graph of 2D view is labeled as functional surface. Then the functional surface which is attached topologically is decided according to the fact that whether they are in the common edge, have concurrent or point in the edge. The azimuth relationship and domain relation are also decided by azimuth vector. The concavity and convexity, qualitative dimension constraint and parametric relation constraint are then defined via constraint panel. Finally assembly structure information model of part engineering drawing is generated.
