Beginner looking for help with "Open objects must be coplanar " error when trying to create a region

Hi

I`m quite new to Autocad and I`ve been following along to various YouTube videos etc. which have been very helpful. I`ve recently had a look at a video that includes a 3d drawing as well as Isometric and I`ve got stuck while creating the 3d view.  The video is by Tim Callinan and is on YouTube  (1998) AutoCAD Tutorial 17 - YouTube.   The part that has been a problem starts at about 56mins.  I`ve drawn the base and the cylinder but I`ve not managed to create a region out of the rib to enable me to extrude.  I keep getting the coplanar error despite having drawn the rib about 30 times.  Can anyone offer any advice or anyway to find out exactly what the coplanar error is ?   If possible I will attach a copy of my DWG.  Its only the 3d part, thats on the right hand side,  that I`m concerned with.  Thanks for reading
