Abstract
An intelligent drawing-model checking method includes: acquiring a first drawing model and a second drawing model, determining an alignment base point according to the first drawing model and the second drawing model, and aligning the first drawing model and the second drawing model into a same reference coordinate system using the alignment base point; determining axis vectors in the first drawing model and the second drawing model according to a standard axis net, calculating a cosine value between the axis vectors, and rotationally aligning at least one of the first drawing model and the second drawing model according to the cosine value; and displaying lines and points in the first drawing model after the rotational alignment in a first color, displaying lines and points in the second drawing model after the rotational alignment in a second color, and checking the drawing models by color mixing distinguishing.
