Often, when I ask why users don't adopt Linux, I am met with the response "There are no CAD (Computer Aided Design) applications. Now I will confess that I know next to nothing about CAD, so I thought I would take a moment to highlight some of the CAD applications available for the Linux operating system, show how they are installed and started, highlight their features, and then let those that know CAD well report on how successful (or not) they are. Sort of a user-generated showdown if you will.
Believe it or not, there are a number of CAD applications for Linux. Some of those applications are far too basic for the professional-level CAD user. Some, however, are just as feature-rich and complex as the industry standard AutoCAD. So hopefully, within this article, you will find a CAD application that will meet your needs.
So, let's get our Linux CAD on!
All of the software listed below can be installed on Ubuntu Linux by following these steps:
QCaD is a powerful 2D CAD application that began in 1999 as a fragmentation of another application (CAM system for engraving and LASER cutting). QCaD includes DFX standard file format and supports HPGL format. QCaD's biggest advantage over many other CAD applications is its ease of use. Most CAD applications are overly complex. QCaD, on the other hand, has a user interface that is clean and easy to use. QCaD features:
QCaD is modular with extensibility being its focus. As you can see, in Figure 1, the interface is very well thought out and easy to use.
Misfit Model 3D
Misfit Model 3D is an OpenGL-based 3D modeling application for Linux that uses triangular-based models. Misfit features:
Misfit does not have the best support available and doesn't seem to support the largest amount of file formats.
SagCAD is another 2D designer for Linux. Upon opening SagCAD, your first thought will most likely be "Whoa, where do I begin?" SagCAD was not created for the inexperienced user. With SagCAD the interface is filled with clickable buttons and no menus. Unless you are familiar with CAD you will look on at the array of buttons and finally have to mouse over each button to know what it does. And to make matters worse, all support is in Japanese! Does this make SagCAD a bust? Only the well-versed CAD user will be able to tell. The good news for SagCAD users is that it is has been around for some time and is still developed and supported. Just make su
Wings 3D is a 3 dimensional subdivision modeller that has outstanding support and features. Wings 3D is available for Linux, OS X, and Windows and features support for numerous import/export formats. Wings 3D has yet to reach version 1 so it is very much in beta. But that does not mean Wings 3D is not already quite usable. Take a look at the small gallery of images created by Wings 3D.
Wings 3D offers a users manual and tutorials for those who aren't sure where to begin.
Blender is probably one of the most popular of all the CAD applications for Linux. Blender features:
If you take a look at the Blender Gallery you will see many reasons why Blender is on of the most popular CAD applications in Linux. I should make mention, however, that Blender does not work well in Linux when full desktop effects are turned on. There are issues with the UI and unless you turn off desktop effects, you will have a lot of trouble using Blender.
Let the tests begin. I have listed five different CAD programs, each of which serves a different purpose. I would like those of you with CAD experience to test them out and see if any of them meet your needs. Does Linux have a decent CAD application? The answer lies in your hands.
