  • Overview capability
  • Zooming at different levels within seperate view sheets.

REPORTING

  • User definable reports

OLE ENABLED

PowaMaster is OLE enabled to allow any OLE enabled application to link with PowaMaster to build nodes on the fly and retrieve the results. This gives the user the ability to use any other interface to link to PowaMaster, such as CAD, GIS or AM/FM.
