The invention discloses a method for designing and realizing an oblique wedge module, which comprises the following steps: A, inputting graphic elements and related parameters; B, carry out
feature extraction, and screening and combine feature elements; C, carry out differential element
processing, jud that measuring direction and envelope of the adjacent contours, and obtaining
graphics set suchas points and finite element which are convenient to be described; D, describe that envelope of the merged contour of the graphic set, obtain the geometric information of the envelope, and matching and selecting an oblique wedge; E, carry out shape and position calculation, and instantiating a set of
size parameter, coordinate characteristics, node positions and that like required by the inclinedwedge module; F, jud whether that shape-position relationship require by the instantiation of the related nodes conforms to the standard; G, outputting the coordinate
system, width, angle and node position required for the instantiation of the
coincidence; H, instantiate that inclined wedge to obtain a visual inclined wedge scheme and an
assembly result; I, carry on the
interactive processing after the instantiation, obtains the final oblique wedge scheme and its related characteristic, the graph, the volume, the tree graph leaf node.
