So you want to have studs for 3d views, but not have them appear in your sections? You could set your studs to a separate layer and toggle that layer off for your sections.
There is no
Junction Order
setting for columns as they do not "intersect" with other columns, they are only involved in
Intersection Priority
calculations. Do you have an issue with them showing up through your wall? Or as you brought up the beams and columns, are they clipping your beams and columns? For the second, can you just change the
Building Material
of your studs to one with a lower
Intersection Priority
?
Can you post some images of your issue?
