Description
Technical field
The present invention relates to DXF File Technology field, relate in particular to a kind of method and system of the DXF of opening file.
Background technology
The DXF file is the cad data file form that is used for carrying out between AutoCAD and other software cad data exchange of autodesk, inc.'s exploitation.Because Autocad is most popular cad system now, DXF also is widely used, the standard on coming true.The DXF file can both be read in or export to most CAD system.In the prior art, open the DXF file just needs to install CAD or corresponding software, take application number as: the CN201110237031.5 patented claim is as example, and the figure that open the DXF form then needs CAD software at first is installed, and opens the CAD environment." the invention discloses a kind of graphic file data processing method and device based on CAD; the method comprises: in the CAD environment, open after the graph data library file; ... ", thus those skilled in the art to open the DXF file all be to carry out in the CAD environment generally all.
Yet CAD software requires higher to the running environment of hardware, open CAD software itself and just need to expend the long time, and in a lot of practical applications, the user only need to open CAD figure, and do not need other function, if adopt CAD software open need to be higher hardware environment, also take processor and internal memory on the one hand in addition, cause the total system operational efficiency to reduce.Existing CAD software itself is how to allow open the DXF file simultaneously, and those skilled in the art also has no way of learning.Cause being difficult to adopt other mode to open the DXF file.
In addition, in Practical Project, the wiring diagram of most of lamp light control system is the DXF file that uses AutoCAD to generate, but this file can not directly use in upper computer software, in order in upper computer software, to generate required effect files, the drawing personnel just must repaint wiring diagram in upper computer software, waste time and energy, and the drawing function that present upper computer software provides is far away not as good as AutoCAD, therefore, how the wiring diagram of DXF file is imported upper computer software and generates wiring diagram and just seem especially important.
Summary of the invention
The objective of the invention is in the CAD environment, to cause the high technical matters of hardware requirement for opening the DXF file in the prior art, a kind of method of the DXF of opening file is provided.Another object of the present invention is that the DXF file is imported to upper computer software and directly generates corresponding wiring diagram.The present invention also provides above-mentioned two kinds of systems that method is corresponding, to realize the foregoing invention purpose.
