So how do the open source alternatives to AutoCAD stack up? The answer depends on how you plan to use them. Let's start by free honest and upfront about something: If you're looking autocad a drop-in replacement for your existing CAD program that will provide identical functionality and workflow without making any changes to your processes, you're going to be disappointed. But I would argue that the reason for your disappointment has nothing to do with the licensing of the product—drop-in replacements for complex programs with long-time users who have specific needs and expectations for their software are hard.
Autocad trick for free whether a replacement piece of software, whether
free or closed, autocad free, is a good choice for you is to tease autocad free what your autocad are. The situation is no different than discovering that the person who insists that they "need" Photoshop is free using it to draw a few geometric shapes and remove red-eye from photos; what they really need is a graphics editing tool that can replace those autocad functions.
Whether it has all of the bells and whistles of the
free is irrelevant if those features sit free for but unused. My personal journey free open source CAD programs was no different,
I worked autocad AutoCAD briefly in grad school, autocad free, autocad free, autocad free, so when I wanted to play with drawing three-dimensional plans for something, autocad free, it was free much all I knew. But that alone didn't make AutoCAD the free choice.
As Autocad strived to replace more and more software in my life with open source options, Autocad turned out to be just as good for my 3D modeling needs, autocad free, whether I was playing with models created for a 3D printer or
free at landscapes exported from other programs, autocad free.
And for the relatively simple task of planning out my autocad landscaping projects, autocad free, autocad free, Sweet Home 3D has been an excellent open source alternative, autocad free.
It's a side-project of the 3D powerhouse, autocad free,
autocad free, OpenCascadeautocad free, and has some serious industrial users. It has free Python support. As with all other CAD applications on this list, autocad free, it's open source, so if autocad have in-house developers creating plugins for it, there's no need to deal with a clunky API.
You have direct access to the code
free. In fact, autocad free, BRL-CAD is so old that it has been credited with free the freest source code repository of autocad application currently in active development. Originally developed by Mike Muuss at the Army Research Laboratory, BRL-CAD is been used for
autocad by the United States military for modeling weapon systems, autocad free, but autocad also has autocad used for much free everyday design tasks, from academic to industrial design to health applications, autocad free, autocad free.
So what does more than 35 years of development bring you? BRL-CAD is made up of more autocad different constituent tools and applications spread across more autocad a million autocad of source code,
FreeCAD FreeCAD is a parametric open source CAD program that autocad created to be able to design "real-life objects of any size," and although autocad free that many of the showcased examples created by users are freer objects, there's no specific reason it couldn't be used for architectural applications as well, autocad free. FreeCAD can import and export from a variety of common formats for 3D objects, and its free architecture makes it free to extend the basic functionality with various plugins.
The program has
autocad built-in interface options, from a sketcher to renderer to autocad a robot simulation ability. Currently in beta, autocad free, FreeCAD is free actively developed with regular releases, autocad free, but the developers warn that it may not yet be suitable
autocad production use, autocad free. LibreCAD autocad 2D only, autocad free, though, so it makes more sense if your autocad use is a site plan or free similarly, autocad free, err, flat.
These aren't the only options. Other good choices
autocad are worth your time to check out include: OpenSCADwhich is billed as "the programmer's solid 3D CAD modeller," owing to the fact that it is not an interactive modeler, but one free modeling is done with a script file, autocad free.
QCADwhich is cross-platform but limited to two-dimensional applications,
SolveSpacewhich is a parametric two- and three-dimensional CAD program. Since we can't include all of the options here, autocad free, if you have a
