LibreCAD 2.0.8 released!

It has been 8 months since 2.0.7, and LibreCAD v2 has become better.

Exciting New Features:

1. DWG read support! Big thanks to our CAD expert @Rallaz ;
2. SVG export support! Salute to @dinkel ;
3. Arabic Language GUI support. More work is needed for:
* Right-to-left support for Text entities;
* Arabic fonts for Text.
4. More user configurable settings in App Preferences.

Under the hood, there’s lots of cleanup and coding style tweaking towards C++11, and the code base should be cleaner for new developers.

There is also lots of GUI and user experience tweaking, mostly following user requests. Clearly, LibreCAD needs help from more developers with the large volume of feature requests and bug reports from our user community.

A list of all commits since 2.0.7 can be found at 2.0.8 Forum Announcement

Feel free to join the development, if you are interested in C++/Qt.

LibreCAD 2.0.4 released

While our new LibreCAD_3 engine is under heavy development as part of the GSoC 2014 program, we will still have LibreCAD-2 developments, bugfixes and new features for this version of LibreCAD. Thanks to help from our small but dedicated developers, LibreCAD 2.0.4 is ready for end users.

Here are some major bugs fixed in this bug fixing release:

  • Windows and OS/X printer dialog fails to appear when running Qt5;
  • A patched version of muparser is used by default for OS/X and win32;
  • Update layer for selected entities when a layer is selected
  • Plotting/drawing mathematical equations by smallfix
  • Draw circle by 2 points and radius
  • PIC file importer by cgrzemba
  • Update layer for selected entities when a layer is selected by ajisaacs
  • Lots of shortcut fixes by thomas
  • Arc angle updates for negative z-axis by coryjc190
  • Drawing order regression in 2.0.3

It may take several days for us to prepare and upload win32 and OS/X installers to librecad.sf.net .

LibreCAD 2.0.1 Released

Update: 2.0.2 was released after two serious bugs in 2.0.1 were fixed.

After two years of development by our small group of developers, LibreCAD-2.0 is deemed stable enough to replace the aging LibreCAD-1.0.4.Two serious bugs  were fixed in version 2.0.1 after the release of 2.0.0 at the end of 2013. We recommend users to upgrade to 2.0.1 from previous versions of LibreCAD. Windows and OS/X users can download 2.0.1 installers at http://sourceforge.net/projects/librecad/files/ . If you come across issues due to upgrading from 1.0 series, please report in forum.librecad.org or at our sourceforge bug tracker.

Some notable changes visible to users:

  1. reworked snapping system to allow simultaneous multiple snapping options; snapping of equidistant middle points;
  2. Helping/scratch layer support. Straight lines are kept infinite and entities are skipped  in printout;
  3. isometric grids;
  4. architectural tick;
  5. support of new ellipse features missing in version 1.0, such as, intersection, middle point, arc length, and tangential direction;
  6. several new drawing features for line, circle, and ellipse;
  7. improved localization, translation for plugins and standard dialogs;
  8. support for a general factor for drawing size dimensions to help scaled drawings;
  9. revert entities direction, developed by effad;
  10. some UI tweaking;
  11. Windows setup registration to add LC in Windows Control Panel
    ‘Programs and Features’.
LibreCAD-2.0 is using a new dxfrw library to handle the DXF file format, and some advantage of the dxfrw library brings are:
  1. New dxf library supporting ascii and binary files, more versions and fully compatible with the specification;
  2. Support of templates;
  3. Dimensions: support for aligned / horizontal text;
  4. Dimensions: added general scale property;
  5. Added support for single line text.
Some internal changes since LibreCAD-1.0 series:
  1. removed Qt3 dependency;
  2. reworked methods to calculate intersections to simplify support for new entity types;
  3. improved many drawing algorithms for performance;
  4. added scripts to allow automatic building on OS/X and Windows;
  5. added boost and C++11 support ;
  6. various code review and bug fixes.
Looking forward to LibreCAD-2.1:
Please share your ideas about the next major release of LibreCAD, and help us reaching there. Help is any form is welcome, and you can talk to us at forum.librecad.org.

LibreCAD 2.0.0rc3 released

In this last release candidate of our next major stable release 2.0.0, we fixed several critical CAD engine bugs related to arc and ellipse classes, and we also improved packaging for both OS/X and Windows.

While the current OS/X installers are more stable compared with our previous releases, we encourage OS/X users/developers to help the stabilization process by testing and reporting issues/patches to our bug trackars or user forums.

Thanks to contributions from our large user community, LibreCAD-2.0.0rc3 supports 46 localizations in 25 languages.

We will start 2.1 forking soon with the formal release of 2.0.0. and interested developers may start sharing their ideas and pull requests by then. Please join us to make LibreCAD better!

The 2.0.0rc3 installers for Windows and OS/X can be found at: http://sourceforge.net/projects/librecad/files/

LibreCAD-2.0.0rc2 released

After nearly three months of hard work, we are glad to announce the release of 2.0.0rc2 of LibreCAD, one more step towards our next major stable release 2.0.0. A short list of commit log is attached for your convenience.

As of 2.0.0rc2, we expect LibreCAD to be stable enough for daily usage, as we have fixed some serious issues since 2.0.0rc1 and have had more time for testing. As a free software project, we highly value feedback from our user community, whether it’s in form of bug reporting, wiki building, template/library sharing, or a friendly chat on IRC.

Our LibreCAD users would be pleased to welcome our new developers who are working hard to make LibreCAD better: Armin Stebich(LordOfBikes) and Tamas TEVESZ (g0rdon).

Beyond 2.0: please feel free to share your vision on LibreCAD-2.1 with our developers.

Thank you and enjoy LibreCAD-2.0.0rc2!

LibreCAD 2.0.0beta2 Released

We are pleased to announce the releasing of 2.0.0beta2 of LibreCAD.

After hard working for 4 months, LibreCAD is stabilizing down after many bug fixes for:

1, dxfrw; 2, printing; 3, OS/X specific crashes; 4, some Windows specific building support;

Please continue to help us reach the stable 2.0.0 release faster by using LC-2.0.0beta2 and reporting bugs to our sourceforge bug tracker. Please note it may take days for us to prepare the the installer files for downloading, while the latest source code is always available at: https://github.com/LibreCAD/LibreCAD

With the future 2.1 version in mind, we would like to hear more about your ideas on  new features expected in our next stable release after 2.0. Some things we have been talking about: Bezier and spline support, better hatching algorithms, geo-reference support, better command line interface, scripting, and scripting ability, etc.

Even more ambitious, we are very interested in porting LibreCAD to mobile platforms, please feel free to talk to us on mobile CAD at our forums: http://forum.librecad.org
