Ribs Direction Issue

Hey, I am trying to create a definition producing vertical ribs for laser cutting from a surface, however cant work out how to align them so they are all facing towards the centre of the loft.

I just cant figure it out, am I just missing some fundamental knowledge of how surfaces work? Any ideas would be appreciated, I have used Vectors to highlight the direction I am searching for, and by chance one of the ribs is roughly aligned correctly so I have green circled this as an example.

Cheers.

Does this help?

I took a different approach... Created a polar array of YZ planes to intersect with your lofted surface, then used 'OffsetS (Offset on Surface)' to get a 2nd curve for each intersection, with which I created an 'EdgeSrf', which is then extruded in the direction of 'Normal' at the center of each surface.

Here is a top view:

Extruding in the direction of surface "Normal" might not be the best choice here... In fact, 'Ext (Extrude)' might not be the best choice; maybe 'Offset' surface instead?
