A hard time for me to figure out that nozzle


Here is the way to do it:
-
Step 1:
1. You vertical sketch has a problem. Delete the line on the flat face and draw it again to create a closed loop.
-
Step 2:
2. Open the loft tool and select the 2 closed sketches you created as profiles.
-
Step 3:
3. Select the open sketch as guide curve
-
Step 4:
4. Mirror the new loft.
Good luck.
