Ubuntu 14.04 (gcc 4.8 + clang):
OpenSource library under X11/MIT license for everyday use. Under development, but some of basic functionality is already available. This project is being developed by Alexandr Borzykh (sandyre) under mentorship of Dmitry Baryshnikov (NextGIS).
Current project state:
| DWG | Read | Write | Features | Missing |
|---|---|---|---|---|
| R13-14 | - | - | - | - |
| R15 | + | - | Reading of layers.Basic geometry reading. Exporting header variables and classes. | Linetypes, CRC calculation, by-block reading. |
| R17 | - | - | - | - |
First you need to download repository
git clone https://github.com/sandyre/libopencadThen, run cmake
cmake CMakeLists.txtBuild the project
make -j4At this point, you will have a static library at lib/libopencadstatic.(your OS static library extension) All you have to do now - is to link library with your project, and include associated header files - opencad_api.h, cadgeometries.h and others.
Then, run cmake
cmake -DBUILD_SHARED_LIBS=ON CMakeLists.txtBuild the project
make -j4At this point, you will have a dynamic library at lib/libopencad{library version}.(your OS dynamic library extension) All you have to do now - is to link library with your project, and include associated header files - opencad_api.h, cadgeometries.h and others.
All you have to do is to link the lib/ directory to your project file tree, that's actually it.
As an example of library usage, there is a built-in app called cadinfo (builds by default with library, available in apps/ directory).
#include <iostream>
# include "lib/opencad_api.h"
// returns nullptr on fail. GetLastErrorCode() returns an error code.
CADFile *pCADFile = OpenCADFile( pszCADFilePath,
CADFile::OpenOptions::READ_ALL );
const CADHeader& header = pCADFile->getHeader ();
header.print (); // prints CAD Header variables.
cout << endl;
const CADClasses& classes = pCADFile->getClasses ();
classes.print (); // prints custom CAD classes
cout << endl;
for ( size_t i = 0; i < pCADFile->getLayersCount (); ++i )
{
CADLayer &layer = pCADFile->getLayer (i);
cout << "Layer #" << i << " contains "
<< layer.getGeometryCount () << " geometries" << endl;
for ( size_t j = 0; j < layer.getGeometryCount (); ++j )
{
unique_ptr<CADGeometry> geom(layer.getGeometry (j));
if ( geom == nullptr )
continue;
switch ( geom->getType() ) // returns GeometryType enum.
{
case CADGeometry::CIRCLE:
CADCircle * poCADCircle = ( CADCircle* ) geom.get();
std::cout << poCADCircle->getPosition().getX() << std::endl;
std::cout << poCADCircle->getPosition().getY() << std::endl;
std::cout << poCADCircle->getPosition().getZ() << std::endl;
break;
// any other geometry type you need.
}
}
}Feel free to submit an issue, or make a pull request. To begin with, it's better to fix some FIXME/TODO's, to get more familiar with code base.
