Error: Unable to create Railing. Please load section file.

Hello Good ABD Community.

I'm having a problem regarding Railings, when I try to place them I get the "Error: Unable to create Railing. Please load section file".

I'm attaching a picture so you can see it.

I think the problem is that is not finding the railing sections on the dataset, does anyone know where they could be so I can reroute them? and does anyone knows the variable that sets this parameter?

Best Regards

Rafael
