Tab and Slot
The "Tab and Slot" 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", "coincident", "Tangent" 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).
The app gives a 10-day trial after the first run.
A subscription can be purchased for $79USD per year.
