Remove Glazing - Does not run OS simulation [Solution exception:Object reference not set to an instance of an object.]

Hi everyone,

I was trying to run the “EP Windows Shade Generator” to keep data trees for cooling, heating and beam energy, but after the simulation, only the beam energy was an output from this component, whereas cooling and heating are empty.
From the Error log I discovered that there is one non planar surface that have window on it.


In order to solve the problem ASAP, I decided to remove glazing from that surface, hoping that this will help (Since that window is not really important for me).
However, after finding the right surface and removing the right window, the “Export to OS” component does not run.

The error log:

  1. Solution exception:Object reference not set to an instance of an object.

Runtime error (NullReferenceException): Object reference not set to an instance of an object.
Traceback:
line 5635, in evaluateZones, “”
line 4717, in main, “”
line 4928, in script
line 6274, in extractPoints, “”
line 5933, in checkZoneSurface, “”

Export to OS with that window works just fine:

Am I doing something wrong?
Or it is a bad bug?

Thank you :slight_smile:

I am facing the same issue. Any solutions to this?

i have similar error!!!

Can you provide more information on how did you remove the glazing? I’m not sure if all these cases are happening for the same reason. A minimum sample file will also be very helpful.
