Webinar: Why Steep and Shallow is Worth Upgrading to the Machining Extension | Autodesk Fusion 360 

Thanks for the great question Craig. By invoking the undercut option in Steep and Shallow you will need to set a threshold angle of "0. By doing this, inherently you are setting all passes to be steep only and as a result all passes using a threshold of "0" and "machine undercuts" checked will only be using stepdown settings.

@@kierangill6602 thanks for the answer. Makes sense. Do you think this can be overcome sometime in the future?

@@craigsmalley8830 Hi Craig , the short answer is Yes. We are actively working to make undercut machining more accessible and flexible in its current guise whilst investigating if other toolpath strategies could potentially leverage some of the benefits that undercut machining options bring

@@kierangill6602 good to know. That means I’ll be able to take advantage of 5 axis machining when this is available. 👍.
