JTB World Inc.

Digitally signed app




Merge, purge and convert Sheet Set DST files. Works with Autodesk® AutoCAD® Sheet Set Manager (SSM) or Autodesk® AutoCAD® Architecture Project Navigator (PN) Sheet Set View as well as other verticals using the Sheet Set Manager.


Run DSTTOOL command in AutoCAD or click on the button in the Ribbon menu. This app will help you:

  • Merge DST files. If similar subsets are found, they will be merged into 1 subset.
  • Merge-Copy DST files: using this method, regardless of subsets duplication, DST files data will be added one after another.
  • Purge unused info in DST files to reduce file size. The purging is useful for IT or CAD Managers to correct performance problems with SSM Sheet Sets that start to perform badly. Sometimes the DST file can grow unreasonably large and the purging can help.
  • Convert DST files to XML format and back. Useful if manual edits needs to be done to the file. Use for Notepad or XML Notepad or other XML editor.


A free trial of JTB DST Tool is available here so you can try it before you purchase it.

Note: This app uses a custom installer (and not the standard App Store installer).
