Bringing CAD to Linux
Christopher Cashell writes "I've often heard it said that linux has the potential to be an ideal CAD platform, and the only thing holding it back is the lack of commercial quality CAD software (a la AutoCAD). Enter QCad, an easy to use 2D CAD project that began as a splitoff from CAM Expert. It was initially released with a 'free for non-commercial use' license, but this has recently been changed to the GPL. It's an excellent program, and earned 5 out of 5 Penguins on Tucow's Linuxberg review." CAD could/should be a "killer app" for Linux on the engineering desktop. I had a conversation a few months ago with an editor at Machine Design magazine about Linux - and how a good CAD app might set off a wholesale migration to Linux by design engineers.
The biggest barier to Linux CAD solutions being deployed in existing shops is not the lack of acceptable CAD programs (there are a few) but rather the lack of compatibility. File compatibility is achieved through native DXF and DWG tralation, but must AutoCAD shops have thousands of custom AutoLISP programs to automate various tasks. I've never seen a Linux CAD prog. that even had a scripting feature much less any degree of compatibility to AutoLISP. My current shop certainly wouldn't switch. Sure it costs us $2,000+ per seat of AutoCAD, but our LISP routines make customizing, editing, marking-up, plotting, etc. a snap and save us hundreds of man hours -PER PERSON- a year. Until a linux CAD prog can do that, it won't be replacing AutoCAD.
Note: Microstation -is- available for Linux, but only as the Student Version (not available to biz.) I know. I talked to them personally.
Here is a list of the Linux CAD progs/projects that I've come across:
