Description
Technical field
The present invention relates to a kind of pattern drawing method, relate in particular to a kind of special scale computer drawing method for scutcheon, belong to printing technology.
Background technology
Along with computing machine popularizing in factory, more and more enterprises uses CAD software to draw, in the sign manufacturing technological process of label factory, the general label figure that will need to make with the CAD mapping software is earlier drawn good in computing machine and preservation, the file layout that then the label graphic file is converted to the laser photocomposing machine compatibility outputs to film setter, and film setter is produced after printing film.Prior art has been done some improvement to the label software for drawing, based on the AutoCAD mapping software, draws label with the method for the parameters of input label circular arc, scale mark, scale value, has improved work efficiency.But to some special instrument label, its main part is a circular arc or many arcs, the scale mark of every circular arc is not conventional line segment, but some special graph, simple as circle, triangle etc., complexity as special graph that little line segment is arranged on rhombus, annulus, all kinds of arrow, the triangular apex, segment etc.Tensimeter label for example shown in Figure 1, the scale of its inside arc are common triangles, and the scale of lateral arcs is the triangle that the summit has little short line segment.There is following problem when drawing this type of label, at first, can realize with clearer and more definite figures of parameter such as the parametrization method for drafting draw circles of routine, triangles, but complicated figure can't obtain the parameter of figure at all, therefore can't draw by the parametric method of routine; Secondly, draw, draw,, have tens kinds, also have hundreds of because the kind of scale graph is unknown but can not all make program module to all scale graph types even all scale graph can obtain parameter.And label enterprise work personnel must go out the anglec of rotation of scale graph according to the deflection angle hand computation of scale when drawing, the scale graph of duplicating needs one by one is to the relevant position, carrying out scale graph more manually rotates, make certain summit of scale graph point to the center of circle, this manual operations descends levels of precision greatly, so draughtsman's workload is very big when drawing this class label at present, work efficiency is not high.
Summary of the invention
The object of the present invention is to provide a kind of special scale computer drawing method for scutcheon, the scale that solves existing label method for drafting is drawn can only be based on line segment, can't draw various special graphs with complex parameters as the scale and the technical matters of carrying out automatic deflection.
