Wire Mode

  • Wire mode allows a user to easily add wires and/or jumpers to a case using only the mouse.
  • It significantly reduces the amount of time required to connect components together.


  • The new Auto-Naming feature automatically increments component and signal names to avoid duplicates.
  • Auto-Naming allows users to easily add many unique bus/node labels and like components to their case and significantly reduces related compile errors.

Quick Access Toolbar

  • Commonly used components can be quickly added to a case via the Quick Access Toolbar.
  • Components can be dragged from the toolbar into a case. A component can be clicked once to be stuck to the mouse, or twice if the user wishes to place the same component repeatedly.

RSCAD FX Conversion Utility

  • A new file format for RSCAD FX has been introduced.
  • Draft files will now have the file extension .dfx instead of .dft.
  • When trying to open a .dft file in RSCAD FX, the RSCAD FX Conversion Utility is automatically launched.


  • More of RSCAD FX’s functionality is accessible through toolbars and/or menus compared to previous versions of the software.
  • There is a toolbar for the main RSCAD FX window and there are individual toolbars for the different tabs.
  • The toolbars are generally user configurable.

Consolidated Settings

  • In RSCAD FX, many settings have been consolidated so that they are easier to find.
  • There are two categories of settings:
    • Global Settings – applied to the whole RSCAD FX application and are accessible from the menu and toolbar of the main application
    • Case Settings – applied to a specific case and are accessible from a Case tab’s menu and toolbar
