Cheers all for your help!

Iv got another question. today Im just experamenting with the software, trying to remember how I used to do this stuff with patch modeling in maya.

Anyway.. what I now want to try is getting this working.

I have made the side section, bolean out the shape and now I want ot patch the face of it. But...no matter how I try this Im not able to make it a smooth object, even though the curves are all snapped correctly (to tangent etc) and Im using the "tangent" option within "sweep" I just cant get it working :(

If any knows something I dont please let me know!
