S-Bend Beam Meeting at Tangents

I'm trying to make a beam that follows this curve:

This curve is sketched on a work plane defined by a grid line. The beam goes on the same plane with a slight Yoffset.This curve is sketched on a work plane defined by a grid line. The beam goes on the same plane with a slight Yoffset.

 

So, I get out the beam tool, I choose the "pick lines" drawing option, and I click on one of the curves. I get this:

So far so good. That's exactly what I expect to happen. We have half of the curve down, so I click on the other half and this happens:

Why on Earth would Revit assume that this is what I want to do? If I select either beam it has the audacity to tell me that the extension/cutback is zero on both ends. It's just decided to draw the beams on some imaginary curve other than the one that I picked. And no, there are no other curves that could have been selected by mistake. Certainly none that would make this result make sense.

 

If I try to draw the beams using the other draw tools the same thing happens. If I try to move the shape handles to get closer to what I indended, I can't actually snap to the tangent point between the two arcs. When I try to eyeball it, I get this:

It's not snapped to the tangent point, and I can't make the edges of the beams join up despite the fact that the curves themselves are tangent to each other.

 

So, how do I go about just making a beam based on that original curve in the first screenshot?

What's that green line?  Are you sure the Beam is actually following that line? 

 

Why not sketch the Beam with Spline?

Edit Beam/Column Join?

So, this is embarrassing, but my actual problem was that the model lines I based it on were imperceptibly off-tangent. It all worked once I fixed that.

 

Now, this still doesn't explain why Revit makes the assumption that I want to curve the beams in the opposite direction, and your suggestion about beam/column joins may address that, but I don't really have time to experiment with it.

 

Thanks anyway for the suggestions.

I think you may have an easier go of it by doing the Beams outside of Group Edit Mode and Adding them to the Group afterwards.  

 

BTW: Beams have a direction. That's in their DNA, so to speak.
