Can't see drawing file in view results tab in EP-Launch

I created my model in openstudio (sketch up) and after exporting to idf file and load in EP-Launch, I can't see the resulting drawing file from the menu in EP-Launch. It showed an error while I click on drawing file tab, thus it does not have any severe errors or warnings when simulating the file.

First, make sure that you are actually creating a drawing file in EnergyPlus. You need to include the Output:Surface:Drawing object with a DXF option, I usually use RegularPolyline for the report specification.

In EP-Launch you need to select a drawing file viewer that can show DXF files. To do this, select VIEW.. OPTIONS..DRAWING VIEWER. You can try using the AUTO FIND button to let EP-Launch see what program is associated with DXF files. If that does not work press the CLEAR button and then you can manually select a program by using the SELECT button. Many programs can show DXF files including some free tools like SolidWorks eDrawings, FreeCad, and VoloView.
