One Line Riser Diagrams

The one line riser diagram is one of the key reports for any design project. Although there is a general format standard for the one line riser diagram, the specifics will vary from company to company and project to project.



VOLTS™ accommodates these diverse format requirements and preferences through its numerous user defined format and information attributes. Additionally, the one line riser diagram, along with all other Volts reports, is dynamically updated with every addition or modification to the project.

  • Effectively communicate and manage design data.
  • Automate the tedious task of creating and updating One Line Riser Diagrams.
  • Eliminate/minimize errors as compared to the manual design process.
  • Export One Line Riser Diagrams to AutoCAD® or other DXF [drawing exchange format] CAD programs with VOLTS Professional. This feature enables you to save time and money by eliminating the need to print reports and schedules and have them manually drafted into CAD files. This function helps minimize errors, increase productivity, and lead to improved design documents.
  • View One Line Diagram in DXF format.
  • View One Line Diagram in PDF format.

Unsurpassed functionality and flexibility permits user defined design preferences

 and customized operating environment

  Printing and Exporting Options:

Prints to any personal or network printer


Exports to a PDF file format (PDF print driver included in VOLTS)


Exports to a bitmap file format (bmp, jpg, tif, gif)


Exports to a CAD DXF file format (Professional and Enterprise Editions)

  The One Line Riser Diagram works in conjunction with VOLTS' Circuit Load Analysis module.

It simply cannot be any easier or more accurate to obtain the correct information the first time.
