![]() Now you can make the parser code more robust to variations in the whitespace ( and also more concise ). */ void CDxf::ReadUntilCode( FILE * fp, int TargetCode, char* lpValue ) * * Read DXF file until get a particular group fp the open DXF TargetCode The group code we are looking lpValue a 255 character array to hold the value string ( may contain spaces ) Size_t p = sCode.find_first_not_of( " ") remove leading whitespace from the group code string sCode( lpCode ) */ void CDxf::ReadTwoLines( FILE * fp, int& iCode, char* lpCode, char* lpValue ) ![]() * * Read next two lines from a DXF file - a group code and a fp the open DXF iCode the group code, as an lpCode a 255 character array to hold the group code lpValue a 255 character array to hold the value string ( may contain spaces ) In order to load sample.dxf file, use the following code: Use LoadFile member function of CDxf class to hold the file. You may improve them for your own purposes. After installation run the app to view available settings and relative information. These classes are in very basic structure. This program adds Windows file explorer support for generating thumbnails for DXF files. CLine, CPolyline, CArc, CCircle and CSpline classes are used to hold the entities. The source code is organized by C++ classes to provide you easy integration into your own code. Highlight and selection of each entity, indication of points, sliding, zoom in, zoom out and pan zoom functionalities are available. Afterwards, they are drawn on the screen. All the entities in the file are loaded into proper classes when the file is opened. ![]() Line, lwpolyline, arc, circle and spline entities are supported. I used C++ classes to provide you easy integration of reader to your project. So, I decided to implement a basic DXF reader supporting spline entity. In the comments of these articles, I have seen that other developers need it. Both are C# code and have no spline solution. NET: Read and View AutoCAD Format Files by Chuzhakin. One is A DXF Reader Solution and Simple DXF Viewer by Evren Daglioglu, another is DXF Import. I searched a DXF reader source code in the CodeProject archive and found two articles. ![]() The Free DXF Viewer is a must have tool.The aim of this tip is to deal with DXF files with the most common AutoCAD entities. The tool is equipped with a straight forward user interface that can be comprehended by even someone who is new to such technology. They can check the object properties copy the drawings onto the clipboard and print them as well. Users can even rotate them with a single click. There is an option to zoom in or zoom out the drawings. This can be done by browsing through the folders or using the 'drag and drop' feature. Once it is initiated, all that the users need to do is to open the relevant files and start viewing them. The Free DXF Viewer also supports DWG files. It uses low to moderate resources and users who are running other programs in the background will not come across any hitches. All those users who have a PC or laptop that runs on Windows OS can make the most of this. This is a standalone app which can be used as a desktop app. ![]() What makes it even better is that it does not require AutoCAD to be installed. This is an extremely effective tool that is easy to use and is ideal for anyone who wishes to access such drawings on their devices. In order to view and print such files, users would require the Free DXF Viewer. This program adds Windows file explorer support for generating thumbnails for DXF files. Get DXF Thumbnails from the Microsoft Store. It is so nice to be able to see the DXF without opening it. It is an acronym for Drawing Exchange Format and is used extensively for drawings. Found this DXF preview app and in works great. DXF files are a flagship of Autodesk and are used to build and share data between AutoCAD and other programs. ![]()
