Real 2D presentation of spatial solids and real presentation rate with fuzzy pattern recognition II—methods and visualization

The axonometric drawing is one of the 3-D object presentations with 2-D. For the coordinate measuring view, fuzzy pattern recognition is utilized, providing the concrete methods and visualized steps for evaluation and determination of the real presentation, analyzing the real presentation rates for the axonometric drawing. Results show that for non-concave solids, the usual solution with ¿real 2-D presentation¿ is the normal trimetric drawing. However, on special occasions, the normal trimetric drawing is not the desired design. For more common situations, it is convenient and efficient to employ the fuzzy pattern recognition put forward by the author to determine the presenting angle and the real presentation rate.
