With the new D&C Scheme Editor 3.0, Bosch Rexroth presents a special offer for design engineers. Free of charge and with no licensing requirements, the circuit diagram software is highly intuitive and easy to use. It also permits the creation of complex pneumatic circuit diagrams in compliance with standards. A comprehensive pneumatic symbol library provides the basis for the circuit diagram tool. Symbols can be easily taken from the library, placed on a worksheet using drag & drop, and connected to a complete circuit diagram. Frequently used symbols can be stored as favorites in a user-defined folder structure. This makes it even easier to create circuit diagrams. Material numbers or designations can be used to search for individual products that are not represented as a circuit diagram symbol. Graphical objects, such as lines, circles and rectangles with many possible settings for colors and types, provide additional options for customizing the circuit diagrams. It is also possible to integrate text and images. The components are aligned on a grid, allowing ports to be arranged according to the grid. The components can be rotated in 15 degree steps. For the individual components in the circuit diagram, the user can assign material and item numbers as well as accessories. Based on this model, parts lists can be generated, which can then be used to start the order process – an important function, both for the documentation and administration of a system. Additional data sheets can be used to expand the circuit diagram. Each individual object can also be hyperlinked to further documents – all in a single application.
