Tab and Slot

Digitally signed app



The "Tab and Slot" for Autodesk® Inventor® currently works with any version of Inventor but was only tested with Inventor versions 2019 to 2023.

The add-in allows for easy tab and slot creation on plate and tube models. It supports the Assembly and Multi-Body part environments.


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).

Trial Description

The app gives a 10-day trial after the first run.

A subscription can be purchased for $79USD per year.

  • 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.
