REALLY FREE
CAD SOFTWARE

There are dozens of "free" CAD programs out there but only a handful are either really free or useful. AAC Labs spent weeks testing the various contenders and found the following to be useful to architects, powerful and fully functional. (We do not include "free" Demo Versions)
  

Just CAD 6.0  [ Download Page ]

JustCad is designed, to make cad drawing as simple as possible. To draw any object, simply click on the screen or snap to an existing object, move the cursor in the desired direction and enter a distance. To change an angle setting for any function, simply click on it's display box and enter a new value. Draw confined to an angle or free cursor with a simple click on the display. Define an Associate, hatch or multiple line by drawing the desired pattern, select it, enter a name and enter the prompted for reference points. Edit multiple objects with a few clicks on the screen. There is no setup for each drawing. Just draw. When your drawing is finished, select all or a part of it, click on the print menu, enter a scale and print.

Since 1999 and JustCad 2.1, until today, with JustCad 6.0, the focus has been to create a user friendly cad program for 2 dimensional drafting needs. Although JustCad supports no industry standards, it is an excellent design platform for home projects and anything which requires simple 2 dimensional drawings. JustCad will draw anything which can be represented with a line, circle, arc, ellipse or text. You can dimension linear, radius and angle.

Your finished drawing can be printed out on any Windows compatible printer. 

JustCad will also create a dxf file, which represents your drawing that can be loaded into any major cad program. The dxf file will contain no actual editable dimensions but a graphic depiction
of them, which will look exactly like your drawing. JustCad is limited in using only those fonts which are available on your operating system. If you intend to share drawings with
others, their system may not contain the same fonts as yours. 
This is an honest description of JustCad's performance. If this meets your needs, JustCad is totally free and you are welcome to download and use it. It's just about drawing. Nothing 
else.

CadStd    [ Download Page ]

CadStd is a general purpose, easy to learn CAD/drafting program for creating professional quality mechanical designs, house plans, blueprints, schematics and charts utilizing ANSI drawing standards. The Lite version is free and can read any drawing created by the Pro version. CadStd Lite can export files as DXF so you can share your drawings to your friends with other CAD programs like Autocad. The Pro version can create isometric projections from orthographic views, and has powerful commands like offset, trim, fillet and chamfer. Export drawings in formats like DXF, SVG, HPGL/1 or use copy clipboard to paste images into Office and other applications. Import DXF, HPGL/1 and Gedcom files.

If you need to create drawings you can be proud to show a client, a city planning department, a government agency CadStd (Cad Standard) is your best kept secret. People will think you spent hundreds or thousands of dollars to create such a drawing. A recent customer wrote : "I have bought a number of other programs, primarily for 3d graphics...but continually come back to this great program for every project requiring drawings."

Desi-III CAD


QCAD Community Edition (Linux)

The project QCad started in October 1999 as a fragment of CAM Expert, which is a CAM System for engraving and LASER cutting. CAM Expert was capable of enough CAD functionality that a spinoff for an independent CAD system made sense.

QCad 1 was an overwhelming success. Within about two years it had an estimated user base of about 70'000, probably more. Its user interface was available in 20 languages and it received top ratings and awards on several occasions.

However, while QCad kept growing, it became clear that there would have to be a major redesign at one point to allow further extensions. That's why QCad 2 development started in May 2002. The main goal of this ambitious project was to make QCad more productive, more user friendly, more flexible and increase its compatibility with other products.

The idea took a rather long time to fully materialize. Almost 1000 hours of design and development in total. But I hope it was worth it. QCad 2 is designed with modularity and future extensions in mind. Moreover a couple of interesting libraries and side products evolved out of the QCad 2 development process: dxflib, vec2web and ManStyle 3.  [Download Source Code ]
