I'm drawing a hub and I cannot figure out how to cut the keyways so they follow the surface of the part instead of heading 90° down the part from the smaller OD to the larger OD.
Whether you created it as a revolve or not, you should be able to use this method (assuming the cone is what I think it is).
Here is another video and SW 2017 part attached. This time the cone is created with a loft feature and then I just do a quick revolve cut to create the interior.
Then you can see me putting the keyways in.
Welcome to the forum. It may be difficult to help without the model, or at least a screenshot, but won't a circular pattern work? (If you'd like to attach your Part, see How can I attach a file to a forum post?.)
I quick sketch or pic of what you're after would help greatly.
Pick the edge of the revolve for the direction of cut and it should follow the edge. See red arrow in the image below.
How were you able to draw a line on the angled surface of your cone?
This isn't something I do often, but I created a separate sketch on the Front Plane that was coincident with the surface and used that line for the direction. I assume Christopher Estelow had done something similar.
It is a line from my original revolve sketch.

Never thought of that. I like it.
It sounds like you are looking at a swept cut rather than extruded cut. You can sketch the cut profile, such as what tool geometry will actually do the cut, and then from a side view of the hub, you can sketch the path the cut will follow. I design quite a few hubs, would be happy to give my input if you have a specific part feature.
Ok, I'm going to give this a try
Since it is a square hole, another way, and maybe easier IMHO, would be to use a sketch that goes along the edge of the cone and then just extrude it perpendicular to the centerline of the cone.
See the attached video and image files.
um, wow you just drew all my keyways and I'm still spinning my wheels over here. I just watched the video-I'm going to give it a try. Thanks!

Attached is a better, more intentional video. I think that it will be easier to follow than the last one (I was moving around a lot on that one).
Okay, I'm back at it. I don't think I can use this solution because I didn't draw the cone using a revolve cut. The interior has a few different dimensions so I didn't draw the profile an revolve.
This did it. Thank you!
You can also create a plane tangent to the cone and perpendicular to one of the axial planes:
Then create a sketch on this plane, using a center rectangle with the center point related to the origin with a vertical relation:
Do a cut extrude to the required depth:
Can't you do a Cut and use the Offset from Surface option with a value and get the same result? This will require an offset plane from either the front or right plane. Dimension doesn't matter as long as it is outside of the part.
Then pattern the cut feature?
Mukesh, the floor will then be radial (conical) I believe he desires a 'keyway' with a 'flat' floor, parallel to cone angle/taper
