[TRNSYS-users] trnViewBUI distorted building model

[hotline]

Dear Cem,

I'm not sure what causes this, but after importing the idf in TRNBuild click save on the b18 file before opening TRNView, that should fix the issue.
I successfully tested it with your idf, but let me know if it works for you.

Best regards,
Christina

I would think so, yes. Keep an eye on the wall, floor, roof, and ceiling areas in TRNBuild. If any of them look abnormally large or small then that would be a red flag.

kind regards,

 David

David,



Thank you very much for your suggestion. I followed your instructions to export the .idf file from TRNBuild. After that, I opened the new .idf file in SketchUp. The building was not distorted. This situation leads me to believe that there might be a problem with the interaction between TRNViewBUI and the .idf file. Is it possible to say it is safe to use the .idf file for further simulation studies?



Regards,

Cem

Cem,

 I have not run into this kind of problem before. However, the *.idf looks fine. One thing you might try is to open the *.b18 file in TRNBuild and select "export Trnsys3D file..." from the File menu. That will create a new *.idf file based on the geometry that TRNBuild understands. The distorted view looks as though one of the wall vertices might have gotten written incorrectly. Once the new *.idf is created open it in SketchUp; if the building is distorted then try reimporting the original *.idf (the one you attached) into TRNBuild.

kind regards,

 David

Hi All,



I created a 3D building model(see attached) using the TRNSYS 3D plugin on Sketchup. I imported the .idf file into the TRNBuild. After that, I checked the surfaces in the GUI, and I couldn't find any problems. However, when I checked the 3D building model in the trnViewBUI extension, the model was highly distorted(see attached). I am not sure if there was an error in the .idf file or the TRNViewBUI extension. Has anyone encountered a problem like this before?



Regards,



Cem
