Parameter Properties

Created: July 28, 2015 | Updated: June 19, 2017

The Parameter Properties dialog


This dialog allows the designer to specify the properties of a parameter, when attached at the project or variant level. Parameters can be used to provide additional design information. Project-level parameters, for example, can be used in global fashion, as the source for special string parametric data to be added to schematic sheets and/or the PCB document - the latter of which does not support localized parameters.


The Parameter Properties dialog can be accessed in the following ways:

  • For a PCB project (*.PrjPcb), click the Add or Edit buttons on the Project Options - Parameters dialog (Project » Project Options from the Schematic or PCB editor main menus).
  • For a PCB project (*.PrjPcb), click the Add or Edit buttons in the Edit Project Variant dialog - accessed from the Variant Management dialog (Project » Variants from the Schematic or PCB editor's main menus) when adding a new variant or editing an existing one.
  • For an Integrated Library project (*.IntLib), click the Add or Edit buttons on the Parameters tab of the Options for Integrated Library dialog (accessed by right-clicking on the entry for the project in the Projects panel then selecting the Project Options command from the context menu).


  • Name - use this field to give the parameter a meaningful name reflective of its purpose.
  • Value - use this field to give the parameter its value.
