Hi guys,
I work for a company called FrameXpert (www.framexpert.com). We have developed a software for working with modular aluminum framing systems that lets you draw whatever you are designing in 3D.
The software is 100% free. Click here to download.
Here are some screenshots:
As I said earlier there is no fee to use the software. You can download it straight from www.framexpert.com and use it for free as much as you want to plan out your designs.
If you decide to order the materials from us (this is how we make money), I can give a discount to CNCzone members. Just shoot me a PM (private message) with your name, zip code, and total order price.
You can download the software here. Let me know if you have any questions!
