The OpenStudio Surface Search Tool enables you to search your model for surfaces with specific attributes. You can select the search results and visually isolate them by hiding all other surfaces. When you are finished, click "Unhide All" on the Surface Search Dialog to unhide the rest of the surfaces. Before searching on a large IDF, close SketchUp's Outliner Window to expedite the surface searching. While surfaces are hidden you can also use SketchUp's built-in "View Hidden Geometry" to quickly view all hidden surfaces.New to the Surface Search Tool with OpenStudio 0.5 and later is the ability to search based on Surface Orientation. You can set both "from" and "to" to a single value if you want to find surfaces that face a specific direction, or you can set unique values to show surfaces within a range of angles. The "Exclude Horizontal Surfaces" is generally intended to be used along with Surface Orientation search to hide surfaces with no azimuth. There are also check boxes to limit search results to non-convex surfaces or to surfaces with more than a set number of vertices. Once your search is complete, the resulting surfaces are selected in SketchUp. You can use this selection for other operations or scripts.
