ERROR - Field [Construction Name] is required but was blank (Fixed Windows)
No matter where I assign the construction, the following errors occur. (Eg. At the building level, space type level, space level, or at the sub surface level.) I thought this error was explained before the move to Unmet hours, but I do not see any post with the same problem. This has happened in other models I have started, but not every time.
I have also hard coded the construction name in the .osm file using Notepad++. However, the idf .err file still shows the blank entry. It is almost as if the fixed window construction lookup (hierarchy) is not assigning the construction at run time.
Any help is greatly appreciated.

NEW INFO:
Apparently extra lines are being created in jumping from the SketchUp plugin to the OpenStudio model. These are called degenerate surfaces in the .err file. See attached for an example. Is this possibly a geometry corruption problem and not the Construction Name lookup?
I will add that the model includes adiabatic surfaces and interior windows. Both are assigned an appropriate construction at the surface/ subsurface level as required.
Ok. Smallest degree of an angle off on one line (the resulting generated wall overlapped between zones) in SketchUp plugin. This does not explain the image above since that is in a different area of the model. I started from scratch and do not see the issues any longer.
