I generated an IDF file and loaded it to open studio. In all the walls with windows (except one in all the 9 story building) the walls become transparent. If I took the window from the wall in the idf, the wall was back on.
I wanted to load a one story idf file to saw it in the form, but can't find a way.
Does anyone know this issue? is that a known bug.
Because I use the model in OpenStudio only for the client to see the model geometry and constructions, It become a must that all the wall could be check.
I found that there is another way to add windows to a wall by adding it relative to the wall. you give the the starting difference from the beginning of the surface, length and height and you do not need to be bother by the exact slop. this solved the issue for me
Window,
0:APT1_Window_83_1_11_97,!- Name
_6-12-6 4.8 - 1002, !- Construction Name
0:APT1_Wall_83_1_11, !- Building Surface Name
, !- Frame and Divider Name
1, !- Multiplier
0.39, !- Starting X Coordinate {m}
0.01, !- Starting Z Coordinate {m}
2.8, !- Length {m}
2.3; !- Height {m}
Display issues like this aren't uncommon in OpenStudio. I would generally expect them with more complicated window layouts than this (unless some of the windows are vanishing too), but some glitches aren't too surprising.
You could try loading it into the sketchup plugin instead to see if that works better (though it's typically worse).
Things that tend to cause problems in my experience can be adjacent windows that share edges, especially if you end up with T-junctions etc. (try to avoid those since they can causes OS to mess up the face coordinates) as well glass doors (if I'm having trouble with a wall with doors I might raise the doors 0.01m to get them off the edge). (see eg. link text for discussion of some similar issues)
Ultimately what's important is that the energyplus file itself is correct. In this kind of situation I'd check the .osm file directly in notepad++ to see if the windows and surfaces are correctly attached to each other. When adjusting geometry in OpenStudio surfaces can sometimes get regenerated and break links between them, so windows get orphaned or you end up with multiple copies of surfaces in the same place, with different windows getting linked to different surfaces etc.
If the model itself is fine on inspection and not showing any errors when you import it into OS or try to run it, then display glitches can be ignored (though they are annoying).
The energyplus file is correct. I do not use openStudio to generate the idf file. I just use it to send my client the OSM file so they can see (visually) the model and can check the construction that are on the right elements.
But if they cant see the external wall, it is a problem As you can see, the windows are not adjacent nor without UK
I found out the I do not have those problem when the wall vector are 0,90,180 or 270, so I guess it is something to do with the slop off the wall and the slop of the window.
but thank you for you answer

While I don't know about the issue with OpenStudio, EP3 can import complete IDF files (geometry, internal loads and HVAC systems) EP3
