Wall Reference Line Side

[Anonymous]

Sorry to have to start a new topic; there are too many already. Many posts seem to skirt this question, but not quite hit it:
Somewhere in here, I think Karl Ottenstein recommended against using reference lines centered in walls because the computer has a hard time figuring out which face is the reference line face. Our office standards locate interior walls by centerline dimensions, and use centerline construction to provide a node to pull dimensions to. Quantity Takeoffs of Interior wall surfaces are in question if we don't know which side of the wall is being used in the calculations.

Wall faces are designated "Reference Line Side" and "Opposite to Reference Line Side" which is ambiguous when walls are created with their Reference Line at the Center. Beam faces are designated "Right" and "Left", with reference to the direction of their Reference Line (Reference Vector, actually).
Anyone know why GS chose to designate wall surfaces using an inherently ambiguous approach rather than the unambiguous approach they chose to use for Beams?

It's all black to me too until I click on it.
Can you see it if you click on it?
The image was "optimized" in Coral Paint Shop pro Photo X2 because it was too big.

This is why I use imageshack sometimes.

What the image shows is that even if the reference line is not in the center where it can provide the needed snap point the schedule can still take into account that the surface is shortened by the width of the intersecting wall.

At least in a T intersection it makes no difference. I didn't check it out for corners.

Because there are several ways to configure schedules to report the surface area of walls, it is possible that you can configure a schedule so that is will report the surface area of the walls accurately no matter if the reference line is in the center or not. Zones come to mind first. If you are using zones as part of how you get your schedules to show the surface area of the walls then the reference line being in the center or face of stud does not matter.

Thanks for this discussion all, even though I've yet to understand it all just yet:-))

(Contractor for 33yrs and center-line of a wall would be a complete mess here).

BTW
The "black" image does not show at all when clicked on here.
