Paid App

A fast and robust tool for adding dogbone fillets to the inside corners of a model. See the video and the full product description below for complete information about what this add-in does and how to use it.

The Nifty Dogbone app now also includes the Nifty Corners command. This allows you to automatically select the edges of sheet stock to create a fillet, as shown below.

Click the correct button below to download the installer for the add-in. If this is the first time you’ve used it, you will automatically be granted a 60-day trial license. After 60 days, you must purchase a license to continue to use it. Purchasing this product will provide you with a license key that you can use to activate the product so it will continue to run after the 60-day trial period.

If you already have a license, installing this will upgrade you to the latest version, and your existing license will continue to work.

Version 1.7.1
Version 1.7.1 is compatible with the Fusion version released in January 2026.
