elMaster is a CAD application for electrical and instrumentation design. With elMaster users can create and update diagrams and drawings such as circuit diagrams and electrical enclosure layouts. elMaster also has a built-in symbol administration with which users can create and administrate complete symbol libraries. The program handles automatically break-up and mending of connection lines when symbols are inserted and deleted or when the whole parts of diagram are copied, moved or deleted.
elMaster has network support for symbol library and lists in order to share them in larger project groups. There is also support for generation of apparatus lists, wire/cable lists, BOM-lists, I/O lists, table of content and so on. Symbols can be already connected to an existing object in database by look-up when drawing. Alternatively, new data object can be directly created in drawing environment.
