# Surface matching/ project loose geometry bug

Hi,

I am teaching openstudio in a energyplus workshop, but it has problems in match surfaces and I am very sad for this. There are many students who has this problem, when they push match surfaces, the openstudio doesn't distiguish some surfaces which have surface outside boundary condition, what is the problem with that? And when they use project loose geometry for drawing subsurfaces, some of them doesnt draw as a window. What is the problem with that?

Wait for your answer eagerly,.

Thanks for your attention, Best Helia Taheri

Try using the match surfaces measure in the OpenStudio application described in this post. It will intersect base surface geometry but won't intersected interior doors and windows. You may consider removing the interior doors and windows unless they serve a specific purpose.

David, Thanks for your answer. But I dont understand surface matchind measure. Where I should downlowd or use it. Thanks, Helia

Choose "Find Measure" under the "Components & Measures". Menu Then search for "Surface Matching" in Envelope/Form and download the measure.

Once you download the measure you apply it through the OpenStudio applciation as described on this page.. There is a checkbox measure argument that tells the measure to run intersection.
