C++ Library for AutoCAD DXF Files Reading & Writing 

Advanced Open Source C++ CAD Library Allows Software Developers to Create, Edit, Read, Manipulate and Parse AutoCAD DXF Drawings via C++ API.

What is Libdxfrw?

In the fast-paced realm of Computer-Aided Design (CAD) and engineering, the DXF file format plays a crucial role in sharing design data across various software systems. But managing DXF files through code can sometimes be tricky. That’s where tools like Libdxfrw step in to assist software developers in effortlessly handling DXF files – whether parsing, editing, or generating them. DXF, short for Drawing Exchange Format, is a file format developed by Autodesk for enabling the interoperability of CAD data between different software applications.

Libdxfrw is a helpful C++ library that is open-source. It helps software developers deal with DXF files by allowing them to read and write them. This library is especially useful for those working on CAD programs, simulation software, or any project that needs to manage DXF files. Libdxfrw comes with various features that make it flexible for handling DXF files. It can read DXF files, create new ones, or edit existing ones through programming, and parse DXF files seamlessly.

Managing DXF data with Libdxfrw is simple and efficient. It provides a strong solution for working with DXF data, useful for a wide array of applications such as CAD software and custom tools that need to manipulate DXF files. Adding this library to your projects is easy due to its clear API and simple usage. Developers can smoothly integrate the library into their C++ applications to make the most of its features for working with DXF files. Its robust features, cross-platform compatibility, and ease of integration make it a great choice for handling DXF data programmatically.

Lading and Parsing DXF File via C++

The open source Libdxfrw library makes it easy for software developers to load and parse DXF files inside C++ applications. The library excels in accurately parsing DXF files of various versions, ensuring compatibility with a wide range of CAD software-generated files. Software Developers can effortlessly extract data from DXF files for further processing or analysis. The following example demonstrates how to parse an existing DXF file inside C++ applications?

How to Parse DXF File inside C++ Apps?

#include 
#include 

int main() {
    DRW::Dxf *dxf = new DRW::Dxf();
    if (dxf->in("example.dxf")) {
        // File parsed successfully
        std::cout << "DXF File Parsed Successfully!" << std::endl;
    }
    delete dxf;
    return 0;
}

Read & Write DXF files via C++ Library

The Libdxfrw library has included complete support for both reading and writing AutoCAD DXF files inside C++ applications. The library enables software developers to manipulate CAD data according to their requirements. Whether it's extracting data from existing files or creating new ones programmatically, the library offers seamless support for diverse file manipulation tasks. The following example shows how software developers can write to DXF files using C++ commands.

How to Write Data to DXF files inside C++ Apps?

#include 
#include 

int main() {
    DRW::Dxf *dxf = new DRW::Dxf();
    
    // Create new entity (e.g., line)
    DRW_Line line(0, 0, 100, 100);
    dxf->addEntity(&line);
    
    // Write to DXF file
    dxf->out("output.dxf");
    
    delete dxf;
    return 0;
}

Manage Layers within DXF Files via C++

Managing layers is crucial for organizing CAD elements effectively. The open source Libdxfrw library makes it easy for C++ developers to add and manage layers within DXF files effectively inside C++ applications. This includes creating, modifying, and deleting layers as per the requirements of the CAD project and thus ensuring proper structuring of design data. The following code example shows how to C++ developers can create and manage layers inside DXF files using C++ code.

How to Create and Manage Layers inside DXF Files via C++ API?

#include 
#include 

int main() {
    DRW::Dxf *dxf = new DRW::Dxf();
    
    // Create new layer
    DRW_Layer layer("NewLayer");
    dxf->addLayer(&layer);
    
    // Add entity to the newly created layer
    DRW_Line line(0, 0, 100, 100);
    line.layer = "NewLayer";
    dxf->addEntity(&line);
    
    // Write to DXF file
    dxf->out("output.dxf");
    
    delete dxf;
    return 0;
