I cannot open an IDF file that was sent to me due to a "draft strictness" error. Is there a known way to remedy this?

Thank you.

@bfrazier could you include the related lines from the error file in your post? That would help others answer your question. Are you trying to open this IDF in SketchUp or IDF Editor? Was this IDF created using an interface like OpenStudio or DesignBuilder?

Aaron, I apologize for leaving that info out of my original post.

The error file reads as follows:

"The collection is INVALID at strictness level 'Draft', because of the errors:

Object level data error of type NoIdd. Error pertains to an object of type "Catchall", named

Additional information about the error type: Input data definition is missing or empty. Field level data error of type DataType."

The IDF was created in DesignBuilder and I am trying to import it into OpenStudio.

This is my first day looking at open studio or energy plus so i'm extremely green

Thank you for the help

One possibility for the cause of this error is that the EnergyPlus version used in your Design Builder install is a different than the EnergyPlus OpenStudio is using. EnergyPlus has different versions. You can translate an .idf to a newer version with the Transition Version option in the file menu of EP-Launch. You can check the version of an .idf file by opening the .idf in a text editor and looking at the Version identifier tag (should be the first object).

Another possibility is that you have objects in your EnergyPlus file that are not yet available in OpenStudio. If so, the error message may tell you what type of object it is having issues with.

After checking version, make sure that all the syntax of idf are correct.

I encountered this problem before not because the version issue, but because my idf file has "for: " in the Schedule:Week:Compact objects. This is optionally for EnergyPlus but OpenStudio somehow regards this syntax as a fatal error.

After I removed "for: ", the import is successful.
