Key Features of QElectro Tech
Diagram Creation
- Allows users to create detailed electrical schematics, including single-line diagrams, wiring diagrams, and control circuits.
- Supports a wide range of electrical symbols and components.
- The software can also be used to create mechanical objects to illustrate processes, instrumentation drawings among various creative possibilities.
Symbols (Customizable)
- The QElectro Tech Software contains many collections (Electrical , Logic , Hydraulic , Pneumatic and Energy symbols and Elements).
- Users can create and customize their own symbols and elements to suit specific project requirements.
- Includes a library of pre-defined symbols for common electrical components.
Elements (Customizable)
- QElectro Tech also consists of an inbuilt element editor that permits creation of newer elements that do not exist in the collection.
- Elements in the collection are not editable i.e. read only. But, once the element is drag dropped into a diagram, it is automatically added to imported collection in a duplicate copy.
- This copy of the element will be available for editing to effect suitable changes to create customized symbols.
- These elements can be selected drag dropped with mouse on to a diagram editor and connected with lines to represent or describe a system. A large number of such diagrams can be drafted under a project.
User-Friendly Interface
- Intuitive and easy to use interface, making it accessible for both professionals and beginners.
- Drag and drop functionality for adding components to diagrams.
- Two tools are used as element editor for creating schematic symbols and a diagram editor for creating your drawings.
Export & Printing Options
- Diagrams can be exported in various formats, including DXF, JPG, BMP, PDF, PNG, and SVG, for easy sharing and printing.
- Supports high quality printing for professional documentation.
- Elements are saved in an xml format.
