I have a file already created in idf format. I am trying to import it into Openstudio, and it works correctly in EnergyPlus. However, it shows an error saying "Finding Construction Layer in workspace failed." then no wall, floor etc. thickness and material is shown in model. How can it be imported as a same model in existing idf file?

Can you share the IDF file and specify the version of OpenStudio?

I added the link of IDF file to my question, and photos of the error lists that are shown

I put the pictures in your original question as they get resized... this was unreadable. But really you should copy the text from the console and post it here instead of putting questions...

As you'll see above, all of your errors are exactly the same type, so no need to paste 50 iterations of it

It looks like you might have a construction in your idf that references a non-existent material, does your idf run in EnergyPlus without a similar warning? Also, it seems like you might have duplicate surfaces or something in your idf, where did you get this idf from?

Actually i created this idf file in DesignBuilder, and in EnergyPlus i dont get any warnings similar to this, it works correctly, then i can get logical results. I entered all layers into walls floors etc. and all of them can be seen also in EnergyPlus.

Currently, OpenStudio can't read all the IDF objects. For example, it can read the geometry from IDF file and it can't read most of the HVAC systems. So far as I know, all the energy modeling tools with good user interface can only handle part of the IDF objects.

So the messages you received is informative. They are not "Errors". You can follow the information to export the untranslated objects.

I checked two BuildingSurface:Detailed for the same wall. They have same coordinates. So the two BuildingSurface:Detailed objects show in the same zone, while the nearby zone shows "missing wall".
