Face sitting gay
there is an angle manipulator in Extrude, but it is for setting the draft angle on the Extrude. It's not really for Extruding at an angle. For that, you need Sweep - define another sketch with a line at the angle you want, then use Sweep to create that angled "extrusion". Here is the draft angle manipulator: Jeff Strater (Fusion development).
That option, extrude from face is not readily apparent in my Autodesk professional Inventor I've often found myself sketching on a primary plane and offsetting from a sketch in SW and would like to do so again with Inventor. I hope to work it out then mirror the new feature across the middle primary plane.
