CAD stands for Computer Assisted Design.

Unlike painting or drawing programs, CAD applications represent real-world objects in their exact real-life dimensions.

CAD programs use a "Vector Graphic" format to store the size and shape of objects such as houses or machines. Rather than filling an area with dots as a Paint program does, CAD programs store the actual measurements of the object.

Scaling is a matter of multiplying these vectors by a scaling factor. This allows drawings by CAD programs to be completely accurate and to show as many details as necessary to produce the object.

If you've used a drawing program such as Window's Paint, you may initially find CAD a little more difficult to use. That's part of the idea, everything is done accurately. The drawing doesn't only look accurate on the screen, it is accurate as a model.
Moving an entity around means moving it from one exactly defined location to another exactly defined location.
Once you get used to this approach, you will always want to do technical drawings using a CAD program.

Why Home Plan Pro?
Is Home Plan Pro the CAD program for you? It depends on what you want to do. Home Plan Pro was designed to draw working plans quickly and easily.

If you are looking for a 3D modeling application, you'll have to look somewhere else. Home Plan Pro is a 2D CAD program. That means that everything is projected onto a plane. That doesn't mean that it's only suitable to represent 2D objects though. Most working drawings are done in 2D. The typical architectural drawing is done in 2D. Architects, builders, and building inspectors prefer it that way.

Why this one?
Some of the reasons why you might want to use Home Plan Pro are its simplicity, Its ease of use, and its affordable price. There are many other capable CAD systems out there and many of them offer much more than Home Plan Pro does. But most of them are simply not affordable for many potential users, costing thousands of dollars, as opposed to Home Plan Pro's $39.00.

Many CAD programs are designed for architects and engineers. Beside being expensive, they are hard to learn, and difficult to use.
You must take classes to learn how to use them, and must use them every day lest you forget the complicated commands and routines.
Home Plan Pro is designed to quickly and easily draw good-quality, straightforward designs.

Home Plan Pro was first released by Home Plan Software in 1989. Although the program has evolved over the years, the price has not evolved, it's still $39.00.
We still offer a 30 day free trial with no strings attached. We don't even take names. You download the installation, or run it from your browser, and you use the fully functional program for thirty days.

If you don't want to keep it after 30 days, just delete it. To keep it, contact us and pay the $39.00.

It's yours forever after that, and upgrades are free.
