How to quickly draw doors and windows on floor plan

Abstract

The invention discloses a method for rapidly drawing doors and windows on a plane room graph. The method comprises the following steps of (1) determination of the positions of the doors and the windows, (2) judgment, (3) calculation and (4) drawing, wherein in the step (1), the positions of the doors to be drawn and the windows to be drawn are determined at the straight line side or the curved line side of the plane room graph, line segments are drawn on the portions where the doors and the windows are arranged, the line segments and the straight line side or the curved line side intersect and serve as the positions of the doors and the windows at the straight line side or the curved line side; in the step (2), the conditions of intersection of the drawn line segments and the straight line side or the curved line side are judged one by one; in the step (3), the line segments serve as diagonals, coordinates of four points of a rectangle to be drawn are calculated, one side of the rectangle is parallel to the straight line side or parallel to a tangent line on the intersecting portion of each line segment and the curved line side; in the step (4), according to the calculated coordinates of the four points of the rectangle, the current line segments serve as the diagonals, the four points are connected, so that the rectangle is established, and the simple doors and the simple windows are drawn. According to the method for rapidly drawing the doors and the windows on the plane room graph, the doors and the windows can be rapidly drawn on the plane room graph.

Description

technical field [0001] The invention relates to the technical field of drawing by computer software, in particular to a method for quickly drawing doors and windows on a planar room drawing. Background technique [0002] In the past, people used a pen to draw on paper, which took a long time, and it was difficult to correct it perfectly once the drawing was wrong. Now computers have become an indispensable part of human production and life. Many people use various software to draw engineering drawings, architectural drawings, graphic design drawings, mechanical drawings, circuit diagrams, flow charts, schematic diagrams and other required graphics on the computer. . Using software instead of paper and pen to draw not only saves time and improves efficiency, but also can be changed many times and stored for a long time. More and more people have begun to learn to use software to draw pictures, and more people have begun to get used to and enjoy the benefits brought by modern...

Problems solved by technology

The doors and windows are an indispensable part of the plan room diagram. If the above two schemes are used, a better door and window diagram can be drawn, but the steps of the fixed process are required, especially when drawing multiple doors and windows, the fixed steps need to be repeated many times. Time-consuming manpower and material resources, the efficiency is not very high
