im trying to modle an end tank to an intercooler. It needs to be as smooth and flowing as possible. im happy with the main body of the part but i need a nice fillet between the body and the outlet tube. solidworks will not do it at all. i belive this is because the back of the tube is flush with the bottom of the tank. i have tryed turning off tangent propigation but it still will not do it. Any suggestions? im still a novice at this program and im the only one with any training on solidworks so im pretty much on my own here.

here is a screen shot with the edge highlighted that i want to fillet.

thanks
