無料ダウンロード リブレCAD
LibreCAD is a fully comprehensive, open source, 2D CAD application. It is available in more than 20 languages and is also cross platform for all major
operating systems, including Microsoft Windows, Mac OS X and Linux (Debian, Ubuntu, Fedora, Mandriva, Suse, etc).
LibreCAD's interface may seem a bit cluttered at first glance, but you will get used to it quickly if you view the very comprehensive Help documentation
that is bundled with the application. The interface basically has a menu bar with a large number of buttons to enable you to add elements easily. There is
also a number of panes that you can view your on-going project from.
LibreCAD supports numerous formats for importing, including DXF, LFF, CXF, JWW, BMP, GIF, ICO, JPG, PNG, PPM, SVG, TIFF, WBMP, XBM and TGA, whilst
exporting is possible using DXF, LFF, CXF, DDS, ICNS, PBM, PNG, ICO, BMP, SVG, TIFF, ICO and PDF extensions.
LibreCAD has plenty of editing and drawing options, including the ability to add lines, points, circles, ellipses, splines, polylines and text boxes. You
can also zoom in and out with ease and move, copy, align, rotate, mirror, scale and trim elements. As well as lengthen, bevel, divide, stretch, delete and
explode text into lettering. So, if you need more than a basic 2D CAD application, then LibreCAD is a good choice; it is well designed, consumes little
resources and is free and open source.
