A coordinate marking method and system of a straight line end point based on an XY coordinate system

Abstract

The invention discloses a coordinate marking method of a straight line end point based on an XY coordinate system, the method comprising the following steps: S1, selecting a straight line, and obtaining the coordinates of a cursor point A when the straight line is selected; S2, determining two end points of the straight line, taking the end point closest to the point A as the mark point B, and taking the direction of the farthest point from the point A to the closest point from the point A in the two end points of the straight line as the vector C, wherein the direction of the farthest point from the point A to the closest point is the vector C; S3, judging the marking direction E and the marking content of the coordinates of the point B according to the included angle between the vector Cand the coordinate system; S4, determining the coordinate mark position G of the point B according to the determined mark direction E and the preset offset distance F; S5, obtaining the mark value Dof the point B according to the mark content, and placing the mark value D at the mark position G. The method solves the problems of complicated operation and error-prone existing in dimension markingon drawings at present, and provides a marking method which is simple in operation, convenient in use and accurate in marking.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a method and system for marking end point coordinates of a line based on an XY coordinate system. Background technique [0002] In the design of various parts in the manufacturing industry, it is necessary to draw three views of the part, mark the three views, and print them into drawings for on-site processing personnel to check the processing content and size. In the commonly used CAD software marking tools, there are diameter marking, radius marking Label, length label and coordinate label, this coordinate label is used to label the X value or Y value of the specified point relative to the XY coordinate system, such as labeling the coordinates of the center of the circle or the coordinates of a groove edge. The coordinates of a point are two values, that is, the X value and the Y value. To mark the coordinates of one of the end points of the line, the current CAD...
