RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

CAD Freeware? - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

-- Antennas

-- CAE, CAD, & Software

-- Circuits & Components

-- Employment & Interviews

I'm looking for a CAD freeware to create one 3D design for an electronics enclosure. It has to be capable of handling one of the following file types:

Pro-Engineer, Solid Works, AutoCAD, .STL, .STP, .IGS

Hi!

You might check out the free version of Alibre: www.alibre.com . They give away free licenses to a limited version of their program.

Good Luck!

Fred

Not exactly what you're looking for, but I've found this software to be very handy.

http://www.download.com/Free-DWG-Viewer ... ag=lst-0-1

It's a free DWG viewer, supports CAD, Iges, dwg, dxf and more. Somewhat related to this post. Hope it helps somebody. I use it every day.

If you work regularly on 3D designs i will suggest using solidworks. It is expensive though.
