DXF library query
Locked
 
|
Hi,
I have been working on DXF files, their generations and other related stuff like providing its support to a particular CAD software. While digging the related stuff on web I come across to the following thread: http://forum.librecad.org/LibreCAD-DXF-File-Structure-td5707695.html As mentioned in this, we can make use of the following already existing library and ease off the work. https://github.com/LibreCAD/LibreCAD/tree/master/libraries/libdxfrw I want to clear my query that whether I could use this same source for my own CAD software without any license issue or I have to work for a new one? |

Hi, This depends on the license of your own CAD software. If it’s GPLv2 or higher licensed then it’s not a problem to use libdxfrw. If you have any other license model you have to check if it’s compatible with GPLv2 or higher of not, you are not allowed to use libdxfrw. Also, please be aware that some licenses are to take in a other type of license, but not the other way around. For example, it’s fine for a GPLv2 application to use a MIT library, but it’s not allowed the other away around. I am not a lawyer, so don’t hang me up on what I just said, check with your own lawyer to make sure. If you are making a open source CAD application, why not help us out!!! :D Feel free to contact me if you have any further questions Ries

Actually am working on a software named DR. Geo under GNU for GSoC2014. Check it here: https://savannah.gnu.org/projects/dr-geo We are currently working on the first version of it, which is having many loop holes and lack of dxf support is one of them. Which I am intended to fulfill as one of my GSoC milestones. > Also, please be aware that some licenses are to take in a other type of > license, but not the other way around. > For example, it’s fine for a GPLv2 application to use a MIT library, If am not wrong Dr. Geo is under GPLv2. > it’s not allowed the other away around. And what could possibly be the other way around? Though I have gone through http://www.gnu.org/licenses/licenses.html but I would like to make it more clear form you. > not a lawyer, so don’t hang me up on what I just said, check with your own > lawyer to make sure. :p > If you are making a open source CAD application, why not help us out!!! :D Yeah, soon I ll be working on that too. It would be my pleasure! :P > Feel free to contact me if you have any further questions Sure! Thanks for the cooperation. :) -- "Today, its a beautiful day, So live your dream.

hello Devinder,
Since Dr Geo is licensed GPLv2 or higher you don’t have to worry about license issues when you are using libdxfrw, so that solves are you problems! If I am not mistaken, the official repo is located here : https://sourceforge.net/p/libdxfrw/code/ci/master/tree/ Good luck on your GSoC project this year!
