    Why do Non-load bearing walls sometimes show up?

    I have the Architectural model linked to my Structural model. I have my Discipline set to Structural. My Visibility Graphics I have set so that I can see walls (expecting to see load bearing walls only.) Why do I see the interior, non-load bearing walls?

    I know, just recently, Architectural has discovered that they need to set a height of a wall relative to the floor above (ie, Top Constraint = {floor level} and Top Offset = -3'-0") These walls that are showing have Unconnected heights. Could this be the reason I'm seeing them on my Structural view?

    You need to add a filter that turns off all walls that are "non load bearing" This setting will need to be set in the Arch model. And the filter will needed to be added to each view. :-\

    If your Arch used a good naming convention you could filter by wall type name, based off the Arch wall types.

      Are you sure they didn't set these walls to bearing in the properties? (I know, probably a stupid question but that's the only one I can think off from the top of my head)

        @Alex: Thanks. I can certainly do that. But, I thought setting the discipline to Structural took care of turning off all non load bearing walls. It seems to work on (most) all other floor plans in all other projects.

        @Martijn: see attached. I've highlighted one of the Architect's non-bearing walls. In the properties it says it's a non-bearing wall. As I mentioned to Alex, setting the discipline to Structural usually takes care of this visibility. I'm just curious why it works in most plan view, but sometimes I'll run across a plan view where the walls show up.


        Does anyone else have an explanation why these walls sometimes show up? I just want to know so I can help the Architects to construct their walls correctly.

          Could you post a part of the project? Shouldn't behave like this... And I can't seem to reproduce it right now.

            Leanne,

            Could you do some testing. You said that you notice this when the wall has no top constraint? Try modifying that wall that isn't working, reloading the link and seeing if it is still having problems. You might also want to try switching the view to Coordination then back to Structural.... Is your linked file set as Coordination? Architectural? or Structural. This setting could make a big difference.

            From my understanding the built in structural settings should work they way you want it too. I have gone one step further with my Arch. We have 2 ways of controlling the walls. I have a added "Structural Use" type parameter in there project as well as a strict wall type naming convention. Between the two I have almost complete control of the linked models walls.

              @Alex: Was just doing that. We tried two walls, just to see. I had the Arch. set the top constraint to the floor above with a -1'-0" offset. Makes the wall the same height as before, but now it's NOT "Unconnected." That wall now acts as desired. ...
              So, now I'm having him go in and change all his walls on that floor and we can educate our Architects in how to create an interior partition wall.

              ETA: Oh, and switching to Coordination view showed me the interior walls above my floor. I had to hide my slab to see the walls below. Switching to Structural view showed all the "Unconnected" non-bearing walls below.

                Very good stuff here. So having an "unconnected wall" seems to effect the structural display controls. Lesson learned, never leave the top of a wall unconstrained.

                Thanks for sharing.
