Yes. nanoCAD is free software. There are no catches, gotchas, or tricks. If you install it without registering and activating it, you may only use it for educational and evaluation purposes. But, once you have registered and activated it, you may use it for commercial, professional, for-profit, or non-profit purposes, as an individual or a business. Registration and activation are free and you will be granted a one-year renewable license for nanoCAD.

nanoCAD Plus with a Workstation Subscription can be used on a single computer only. License can’t be transferred.

nanoCAD Plus with a Network Subscription can be used on any computer on the local network. It requires an installation of the License Server (supplied).

See detailed instructions on how to install and register nanoCAD.

Registration and activation are not required to run nanoCAD. If not activated, nanoCAD will run in Demonstration mode. In this mode nanoCAD is fully functional, but a “Demo version” watermark will stamp will appear on any prints you make. Under the terms of the software license, when running nanoCAD in Demonstration mode, you may only use it for educational and evaluation purporses.

• If you wish to use nanoCAD for commercial, professional, or other purposes, you must register and activate it—at no cost. Once you do this, your copy of nanoCAD will be activated for one year. (You may renew that activation when it expires, or update for free to the newest version of nanoCAD.) More on nanoCAD registration-->

A big part of our business is CAD applications development for various industries. We developed nanoCAD because we needed a high-performance, reliable, compatible, and economical CAD platform on which we could build these applications.

We give nanoCAD away because it makes good sense. It lets our customers stop worrying about how many copies of CAD software they're using, and simply give a copy of nanoCAD to everyone in the company who might need CAD.

Of course, you might wonder how we can stay in business giving software away. Of course, we don't give all our software away.

• We sell a large number of advanced CAD applications that run on the nanoCAD platform. You may visit http://nanocad.com/page/nanoApps to see a list of some of our applications. Many are being updated to support international languages and standards.
• We partner with other software developers who use nanoCAD as a platform for their CAD applications. (We make building on nanoCAD easy, by providing free membership in the nanoCAD Developers Club.) And,
• We sell subscriptions to nanoCAD Plus, a premium version of nanoCAD, with a suite of advanced features. A subscription to nanoCAD Plus includes updates, and priority online support, and is very affordably priced.
