In the example below, the Add Extrude function is to be used to extrude the circle. The extrude direction is to be along the center of the conic feature.
By default, the extrude direction is normal to the sketching plane, in this case, vertical.
Click on the arrow origin, and from the menu select Cylindrical / Conic Center. You can now pick a cylindrical face, conic face, revolve face, circle, arc, or circular edge to which the extrusion will be normal.
Pick the conic face shown below. (If the extrude direction points the wrong way, you can click on the arrow head or body to flip the direction 180 degrees.)
To get the same results, you can also pick one of the circular edges.
The extrude direction is now the same as that of the cone.
