For the time being we stick to that, moving to GPL 3 has no evident benefits I know of. It's fine for applications, because it doesn't hurt at this point, but, in my opinion, not for libraries that are designed to be used as freely as possible." "Blender is also still "GPLv2 or later". I don't like dogmatic ideologies, and freeing software by force (as GPL/GNU does) is something I dislike in particular. It prohibits its use in Assimp and for many other applications as well.

A request also went to the FSF to relicense GNU LibreDWG as GPLv2, which was rejected. The GNU LibreDWG library is released under GPLv3, so it cannot be used by GPLv2-licensed LibreCAD (and FreeCAD) because their licenses are incompatible.

Originally, the GUI was based on Qt3 libraries.Ĭurrently, the GUI of LibreCAD is based on Qt5 libraries, so it can run on several platforms in the same way. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application.Īround 2010, the QCAD Community Edition v2.0.5.0 was forked to start the development of what is now known as LibreCAD. It is free and open-source, and available for Linux, macOS, and Windows operating systems. QCAD is probably about twelve years or so behind AutoCAD in terms of development.LibreCAD is a computer-aided design (CAD) application for 2D design. However, in this instance, the open source program just doesn’t cut it. You know, it’s odd that a Free Software supporter such as myself would choose the proprietary software over the open source. For non-professional home/hobby use, it can be made to work, but I wouldn’t even think about doing some of the the things that I do with AutoCAD with it, even 2D (and considering I do the majority of my drafting three dimensionally…). However, the user interface does not present itself very well for a professional draftsman (which definition I fit, even if in the current economy that’s not how I make my living). Looking around in QCAD, it isn’t bad feature-wise for a 2D drafting program, and has come a long way since the last time I mucked about with it. Well, since in QCAD all the points in the splines must snap to existing entities, it makes it difficult to trace things out. I’ll trace out the stations of a ship with splines, arrange them three dimensionally along the profile, draw in the water lines (which are also splines) and fair everything out to get a nice, smooth hull. I use splines probably more than lines when drawing ships. It has to be manually done by the little icons on the left hand side. It’s just one click, and boom, lines can be drawn.īut wait, it doesn’t end there! When one is done drawing the line(s), one cannot simply hit a couple of times and get out of line drawing. When it comes down to it, AutoCAD has the same choices, but they all get their own separate icons. But wait, rather than then being able to immediately draw a line, one is presented with choices for a bunch of different lines. The alternative is, like in AutoCAD, to click on the little icon in the toolbar. In QCAD, one has to click on the text box at the bottom, which is very frustrating. No clicking in the text box at the bottom is necessary. In AutoCAD, one can simply hit ‘l’ (or ‘L’, but the extra keystroke is not necessary) on the keyboard to draw a line. Number one on the list, though, is that QCAD is useless with my drafting style.
