promis•e ® 2007- ECAD Software - The Logical Edge in Design Many companies use mechanical design software as a tool to model manufactured goods, vehicles, machines, and other material objects on a computer screen. In many cases the electrical portion of the design process was a second thought and companies used the same software to manually layout the electrical schematics for these products. This method is very time-consuming and can lead to many errors in the electrical design process.With promis•e 2007, you have powerful help in the following areas: Drafting Aids - Construct schematic diagrams quickly using the promis•e 2007 drawing editor. Libraries of symbols and the ability to create macros allow you to point and place the main components of your drawing and swiftly connect them with wires, which are broken automatically at connection points. Error Checking - as you draw, promis•e 2007 alerts you to errors in the drawing. This reduces the amount of manual checking that must be done, improves the overall accuracy of the drawing and prevents costly corrections later on. Error conditions include short circuits, gaps in the circuit, duplicate device IDs, duplicate wire numbers, missing part numbers, missing cross references, and over-assignment of contacts (for example, five contacts for a four-pole relay).
