I'm able to use the Delete Face feature to combine all these surfaces into about 5 surfaces. Now I am trying to combine these 3 surface into 1 so I can do either an extrude boss/cut Up to Surface feature (see blue highlighted below):
I tried to do continue using Delete Face feature but it's distorting the surfaces. I've also tried to do Surface Knit but I am not certain how to fully use it because it's not combining the faces. Any suggestion?
