image description i am using Sketchup 2017 with Openstudio 2.1. I run the intersect function and then match the surface for the entire model. However, the result didn't seem great like the screenshot. I created the model with great discretion without making any unnecessary room intersections. Is there any solutions for this?

You can change surface boundary condition by inspector in sketchup

You are right. However, in some circumstances, one surface connects to two other surfaces. So using the inspector won't work. Also it is very time consuming.

"one surface connects to two other surfaces" there is one problem. Use the intersect tool before surface matching. If spaces aren't dividing or matching, then likely something is wrong in the geometry, or you have duplicate surfaces. Try restarting sketchup and seeing if you get duplicate surface warnings.

Yeah, I've been having this same problem since the update to V2.0 (or 2.1, not 100% sure). It is pretty annoying. I believe the issue is with the intersect function rather than the match.

Just select the whole building or spaces you want, click on the upper menu on "extensions > OpenStudio User Scripts > Alter or Add Model elements > intersect space geometry". After this you can apply surface matching for the building. It worked fine for me.

I found that the most efficient way to match the surface is not inside Sketchup. Applying surface matching measure in OS download from BCL developed by David_Goldwasser will solve the most the problem. It will just take a bit more time, since it will only match one pair of spaces vs all the spaces. image descriptionNow everything is perfectly aligned. Reference link is here:
