Following features are planned for LibreCAD-2.0.0:
- better spline and Bezier curve support;
- complete conic section support after adding of hyperbola and parabola entities;
- draw a circle/ellipse tangential to two selected circles/ellipses.
With these terrific features, LibreCAD is expected to work as a general geometry tool even for users who are not in the CAD field, while those features are extremely useful for CAD users as well.
Due to complexity of those exciting features, we call on interested developers to join our development team to further develop this lightweight and feature rich free software.
2.0.0_alpha3 is expected in next one or two weeks with many bug fixes since 2.0.0_alpha2. fparser has been removed from LibreCAD. From now on, LibreCAD depends on muParser ( http://muparser.sourceforge.net/ ).
If you find a bug in LibreCAD, or simply want LibreCAD to do more, please talk to us on #librecad at freenode or file a feature request/bug report at our sourceforge trackers:

I love u people!…… son grosos….. sepanlo!
Please give me an Autosnap!
I am not able to help. Does the code of open source geometry software can help you?
Congratulate for your work.
Yes, if we can port the code/algorithms without licensing issue, currently, LibreCAD is mainly GPLv2, with all additional code in GPLv2+.
I’m in the process of hyperbola/parabola implementation. LibreCAD should be able to draw all conic sections with construction algorithms.
Thanks,

Implemented in master branch:
draw a tangent circle passing two given points.
This implementation is an example of using LibreCAD’s new powerful quadratic form framework. The path of a circle’s tangent circle passing a given point is either hyperbola or ellipse, and to locate the center of a tangent circle passing two given points, two quadratic forms are formed for each of those two points, and the intersections of the quadratic forms are candidates of centers of tangent circles.
I am still learning about it, can I ask ~ what does Bezier curve support for? How significant is it? Its the first time I heard about it. BTW, its good to know about this new features.

Will LibreCAD work with Windows 8?
Where is a spreadsheet support ?
Quiero copiar un objeto y no puedo, quiero mover un objeto y no puedo, quiero hacer simetría y no puedo…¿de verdad hay algo que si se pueda hacer con este programa?
