Connect Extrude to Spline Revolve (with a Loft)


probably a newbie question but I'm stuck and the search did not help either...

I have a kind of bowl I created from a spline that I revolved and thinckened afterwards. In this bowl there is a vertical platform that was created by simply drawing a rectangle at the bottom and extruding it.

Now, what I really need is the platform to go from one side of the bowl to the other to separate it into two parts (as indicated by the transparent area). I guess this could be done with a loft, but as I cannot put any vertices on the surface of the bowl I have no idea how to do it. 

Thanks for any help! The document can be found at

    Thanks a lot, guys! Actually, both answers are helping me a lot. I did not know about the "up to part" option before - that is pretty staight forward. The way using Boolean feature is also pretty clever and the technique is something that'll be of use for me.

    I must admit I hadn't used the delete face feature before, and this example shows a very useful situation for it. However, somehow it still feels like it's not proper modelling, though. :-)

    NeilCooke,I know your way is better ,it can save some steps, but I just want to share a different way! All roads lead to Rome!

    @shanshan - indeed!  There are always several ways to model something.  For example, you could have created your extrusion using Add (so it's all one part) and then used delete face to remove the bits sticking out of the sides!
