The problem it's that even following other people's advice i still have all my building surfaces without a construction name. I had created a construction set with all the types of constructions in Open Studio. Then i selected the whole model also in SketchUp Plug-in to set my "construction set" using the "Set Attributes Tool". I tried also to use the measure "Remove Orphan Subsurfaces plugin" , but nothing. I cheked also if the model has glass doors, but it's not that problem. So the funny thing it's that only fixed windows has the correct construction name. Other surfaces have everything in theyr places (name, surface type, outside boundary condition) except construction name. How can I fix this problem?

Are you getting missing construction errors for all surfaces (except windows) or just a subset of surfaces? Also are you using adiabatic boundary condition anywhere?

It's for all the surfaces. I used adiabatic boundary just for a few surfaces which have same problem.

Open your OSM with the OpenStudio application and see that your construction set looks similar to the example in the documentation.

You can then apply that construction set to the entire building, a building story, a space type, or individual spaces. It sounds like you tried the last approach (spaces). That should look like this, but would would have it applied to every space.

If you want the same construction set used everywhere the most direct way would be instead to apply it directly to the building object, which would look like this.

With either approach if you look at surfaces you should see most construction names in green (these are inherited vs. hard assigned.)

Notice that the adiabatic surface in my example doesn't have a green construction. That is because our default construction set is only setup to handle ground, interior, and exterior boundary conditions. There is a feature request to extend it for adiabatic, but for now you have to hard assign constructions to adiabatic surfaces. You can do that manually, in the app this is done by dragging a construction from "My Model" or "Library" to the dropbox for the surface. There is also a user script in the SketchUp plugin to set selected surfaces to adiabatic and assign a construction.

OK, now seems it works!Really thank you!Just one thing, even if the simulation doesn't show problems, in the sketchup plug-in surfaces still doesn't have a connection with the construction name. Anyway it's ok

The OS APP shows inherited constructions but the SketchUp Plugin inspector does not; however render by construction in the SketchUp plugin does show them, and if you select a surface it will show you that construction object.
