The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: Index=n (where n is in the range 1 to 10)


This command is used to open the indicated reference document - specified through a defined underlying URL link parameter - for the selected component in the Libraries panel.


With a named document link for the component already defined, the command is accessed by right-clicking in the Components or Models regions of the Libraries panel, and choosing the applicable command (the link parameter name) from the References sub-menu.


This feature is available when named document links have been added to the library component.

After launching the command, the indicated target document will be opened. A web-based URL target page will open directly (if available). For a PDF or text document, a search for the document is conducted as follows:

  • If a path to it is specified, this location is searched first,
  • If the document cannot be found at this location, or if no path is specified, the \Help folder of the Altium Designer installation is searched.


  1. A web-based URL will be open either in an external browser, or as a tabbed document within Altium Designer, as determined by the Open internet links in external Web browser option, on the System - View page of the Preferences dialog. Bear in mind that to open in an external browser, the value for the named link's URL must include the http:// prefix.
