Extrude 3
This video is an in-depth tutorial on advanced uses of the Extrude command in Fusion 360, focusing on the various termination options that define where an extrusion starts and ends [00:00]. It begins by showing how to create a part and then how to sketch on origin planes or existing faces [00:35]. The core of the lesson details the different termination types: using a Distance (positive for adding material, negative for cutting into the part), using To an Object to make an extrusion or cut stop exactly at a selected face, and using an Offset from that object [03:05, 03:43]. A key concept demonstrated is the power of using the "To an Object" or "Offset" options to maintain a consistent geometric relationship even if the original part's dimensions change [04:00]. The video also covers using the Offset option for the Start of an extrusion to move the feature away from the sketch plane [06:48], utilizing the Project (P) command to reference distant geometry in a current sketch [05:35], and creating Symmetric extrusions centered on an origin plane [08:11].
