Tab and Slot

Digitally signed app



The "Tab and Slot" preview for Autodesk® Inventor® is a free add-in and it currently works with any version of Inventor but was only tested with Inventor version 2019 to 2023.

The add-in allows for easy tab and slot creation on plate and tube models.


Any uniformly thick parts can be used to create tabs and slots. Further to that, "center drilled" and "coincident" or "dog-bone" recess fillets can be added automatically to the Tabs or Slots or both.

The add-in supports Metric (mm) and Imperial (inch) units.


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

  • Great Time Saver.
    Brad Gates | February 16, 2022 Verified Download (What's this?)

    This is a real time saver!! I just wished that the slots would move with the part, it you constrain a part and make your tabs and slot and the decide you want your part with the tabs over say a 1/2 inch the slots do not move with the part, that is the only down fall I see.   Other then that it is great.

    Pieter van der Westhuizen (Publisher) | March 16, 2022

    Thanks for your feedback. We will investigate this and add the improvements in the next release.

  • Nice Tool
    Geert van Pelt | February 04, 2022 Verified Download (What's this?)

    Nice tool works good in assemblies and saves a lot of time.

    However I use multibodiparts and would also like to apply it in a part file if possible.

    Pieter van der Westhuizen (Publisher) | February 08, 2022

    Thanks for the great review and feature request. We will look into adding multibody support.
