EZ Schematics - An Easy to Use Cad Program for Developing Electrical Schematics and Line Diagrams. Whether you're an Electrical Engineer, a Student or an Industrial Maintenance Electrician, there's simply no easier way to draw and print electrical schematic diagrams than with EZ Schematics. This software program was designed by an industrial electrician with over 20 years experience in both troubleshooting and training in control relay logic (similar in many regards to PLC logic). The application, established in a line diagram format, provides the end user with the ability to quickly and easily transform logical concepts into a professionally diplayed electrical schematic. Admittedly, as a stand-alone CAD program, EZ Schematics does not offer all of the features nor the capabilities of AutoCad and other well established CAD software applications. But with the learning curve set far lower than the aforementioned, you'll never find an easier method to transform electrical relay logic concepts into digital documents (as line diagrams) that can be saved and printed with professional appearance.
