Missing wall in Elevation

[Anonymous]

Hello. I hope someone could help me on this. When I load the Elevation in my model, some of the walls disappear, and when I delete the column that's in front of it, wall comes back but with a square in the middle. What does this mean ?
or how can I fix it ?

I added a picture so you can see.

Thanks!

Could be several things. Do you have a wall skin of 0" thickness? That will do it. Also, I have had the same thing happen to me recently as if I am short on memory or something. It takes some doing to make it rebuild. Is your file very large? It could also be some kind of material strength setting, or intersect number for a layer. Show us what it looks like in a 3d view.

This is the 3d view, and it looks all complete. Now the elevation is fixed cause' I rebuilt the wall, but I still don't understand why sometimes elements tend to disappear in elevations. I think it could be like you said something related to the rebuild thing.

Here you can see that in this elevation half of the floor is missing, what could it be ? I just bought an iMac last week, so I can delete the ram issue now, but I think it can be something else, because it worked before but now is like this.

Is it possible that you have to elements (ie. walls or slabs) in exactly the same place and they are effectively cancelling each other out?
