Deleting degenerate surfaces in OpenStudio

Hi,

After running my simulations in OpenStudio, the error messages are telling me I have 24 degenerate surfaces. How do you identify these surfaces in OS and remove them?

Thanks

What I would do is:

Export your model to an idf file. Open it with IDF editor and, add a "Output:Diagnostic" object and set it to "DisplayExtraWarnings". Run the simulation and look at the ".err" file. It will tell you which surfaces are degenerates. Then, go back to Sketchup or to your ".osm" file and delete them.

@DavidGoldwasser, @DanMacumber, is there no measure for this?

This is the measure to add Output:Diagnostic objects to a model.

The diagnostic script in the SketchUp Plugin user scripts does this. Set both arguments to true to remove small surfaces. Not in measure yet :(

Why does it happen ? Almost all my interior surfaces are degenerate, either with missing surfaces or with extra lines in it, and I have to redraw them manually.
