Hi @troyalexbrandt ,
No problem! I attached a file of what I am talking about. Sketch 2 has the geometry of the circle projected onto it. You can do this by going to sketch>project/include> project and selecting the circular body that you want to use. I then sketched some lines that extended to the circular geometry.

The purple lines are the geometry that has been projected (the circle), and the blue is what I have just sketched. I then extruded from my new sketch, and you can see that the extrusion follows the geometry.

Feel free to look at my attached file for reference. If this extrusion is not your goal, please let me know. If you need more help please attach your file in your reply.
Thanks!
