Sign manufacturing computer drawing method

Abstract

The invention discloses a sign manufacturing computer drawing method which comprises the following main steps of: drawing a main circular arc; selecting a scale line type; enquiring whether an arc scale is equally divided; if selecting equal division, inputting an equally divided scale line parameter; if selecting unequal division, inputting a scale line parameter rotating according to angles or inputting the scale line parameter rotating according to a relatively fixed value offset multiple; meanwhile, drawing scale lines and scale values; if needing to draw a subsidiary arc the scales of which have a corresponding algorithm, inputting the corresponding algorithm; inputting the arc parameter, the scale parameter and the scale value parameter of the subsidiary arc; and drawing the subsidiary arc, subsidiary arc scales and subsidiary arc scale values. The invention solves the technical problems that a traditional drawing method can not set the corresponding algorithm of the subsidiary arc and can not automatically compute the scale corresponding relationship or automatically draw the subsidiary arc, reduces the drawing time and improves the work efficiency.

Description

technical field [0001] The invention relates to a graphic drawing method, in particular to a computer drawing method for making signs, and belongs to the technical field of printing. Background technique [0002] With the popularity of computers in factories, more and more companies use CAD software for drawing. In the sign making process of sign factories, CAD drawing software is generally used to draw and save the sign graphics that need to be produced in the computer. Then convert the sign graphic file into a file format compatible with the laser imagesetter and output it to the imagesetter, and the imagesetter prints out the film for production. At present, some improvements have been made to the sign drawing method. Based on the AutoCAD drawing software, the sign is drawn by inputting the parameters of the sign arc, scale line, and scale value, which improves the work efficiency. However, for some special signs, such as the signs of thermometers and refrigerant meters,...

Problems solved by technology

However, for some special signs, such as the signs of thermometers and refrigerant meters, the main part has two arcs, and the two arcs have a certain corresponding algorithm, that is, there is a unit conversion relationship. The parameters of a standard arc, such as the parameters of the arc of Celsius in the thermometer, but the parameters of the arc of Fahrenheit are not available. At this time, the staff must first calculate the Fahrenheit parameters corresponding to Celsius one by one according to a certain correspondence algorithm and input them into The complete sign graphics can only be drawn in the parameter table, and there are many similar situations. Therefore, when drawing such signs, the workload of the draftsman is very heavy and the work efficiency is not high.
