walls centerlines

Question

Can walls' centerlines geometric data be accessed in any way either within ABD or within Generative Components?

Ah, I see. Yes, AFAIK the Wall Assembly creation tool is designed with a single wall length in mind, so a vertical mullion would not fit into that framework. It sounds like you are currently creating a simple solid and then arraying that along the length of the wall? If so, a Polar array using the arc wall's center would effectively do the same thing, though obviously it wouldn't result in a single element and it's certainly not as slick. I'm not sure if anything like this is on the backlog, so it could be worthwhile logging a Service Request with support with the applicable details of what you'd like to see so that an Enhancement request can be filed (assuming one does not exist). 
 
It should also be possible to create a curved version using PC Studio since the delivered Curtain Walls (via the Curtain Wall tool) are straight lengths, but that of course requires the knowledge to do so. Perhaps someone here has done something similar?

Huh... you and me both. :) Another potential option suggested by a colleague would be to create a custom linestyle that uses a 3D point cell, though while I know that's possible I've never tried anything like that in this particular context. Even a line (using this custom linestyle) could be placed for the graphic component, with DataGroup data for the applicable wall applied after the fact. Just thinking outside the box.
