Hi everyone,

I am trying to create a multi-dimensional sketch of an airfoil. The sketch looks like so:

As you can see, the small .25 inch half-circle in the center of the photo is on a flat plane, so I added some splines to attach it to the large circle. Is there anyway I could avoid this issue entirely by creating a curved plane tangent to the large circle? The reason for the small half-circle is to insert a ball bearing & create a rotating airfoil axis. However, despite the fact that all of the lines intersect, I still get the error "Select a continuous group of entities". How would I be able to get this to be a continuous sketch so I could sucessfully perform a sweep function?

I already created a similar airfoil as seen below, but now all I need to do is add the half-circle to the sweep of this airfoil.
