Chain Search & Replace (12d App)

A 12d Model application that allows for search and replace of values within 12d Model chains. The search can be narrowed or widened to only include particular chain commands.

This macro only works on the newer XML-based chain format introduced in 12d Model 10. Supported files have an extension of .chain . The older, non-XML format chains have a .rcn extension.


  • Currently supports all V10 chain commands
  • Search and replace can be limited to only certain commands
  • Makes a backup of existing chains before making changes (can be disabled)
  • Able to update UIDs of replaced elements (e.g. strings, tins, models)
  • Can be case-insensitive
