Hi, I am trying to take advantage of BEopt's capability to rapidly generate residential building envelopes. The idea is this: I wanted to use BEopt to sketch the geometry, export it as IDF, then import it into OpenStudio and save it as .OSM file. Then there is an error that is related to "draft strictness". I figured it is because OpenStudio is quite limited in terms of importing IDF files, based on my research.

So what I did next was to first open the BEopt IDF with SketchUp to get the geometry, then save it as .OSM from SketchUp. When I open this file in OpenStudio, everything seems fine. But when I tried applying a measure by going to the measure tab and drag-drop them from the library, an error appears and OS crashed.(screenshot below)

I've tried several times. The same error pops up. Is there a way to solve this? Or is this kind of file conversion not recommended in terms of workflow? I wanted to do a small parametric analysis of a residential model using the OpenStudio PAT tool, and BEopt is very good at making a standard residential model.

When you go to the measures tab OpenStudio generates an IDF file, and that is what is crashing. Can you provide some more information? What version of OpenStudio application gives you the "draft strictness" error? What version of OpenStudio doesn't give you the error when you open it in the OpenStudio SkeetchUp plugin? What version is the IDF file you started with?

Also wanted to point out there is a lot of ongoing integration work with OpenStudio and BEopt including a common 2d geometry editor. Here is a recent post about using BEopt with OpenStudio that may be useful for you.

I used OpenStudio 2.1.1 for all my above descriptions. The IDF file I started with (generated by BEopt) is version 8.6. I have tried updating the IDF file version using the E+ version updater tool to update to 8.7. Both versions gives the same draft strictness error as such:

The collection is INVALID at strictness level 'Draft', because of the errors: Field level data error of type DataType . Error is in an object of type 'Schedule:Week:Compact', named 'BathExhaustWk_1', in field 1. Additional information about the error type: field-level data is of an incorrect type

yeah, I have been reading this repo as well. Thanks for the confirmation.

Did you ever solve this? I'm interested to know the answer.
