Dear All,

I am in trouble in the modelling process . For my research project , I used Revit Architecture and exported both gbXML and .dwg format. Firstly, I am not able to import gbXML into sketch up to Openstudio.Secondly, after importing .dwg format as 3d model solid I can not create no wall thickness as faces in Sketch up .Please let me know if I have to model no wall thickness to simulate in Energy Plus or not. Would you please guide me by offering any information. Yours sincerely,

welcome @shahryar - I added tags to your question so it's searchable. Here's a previous question about wall thickness in SketchUp...

shahryar, when you ask if you have to model with no wall thickness, do I correctly infer that you are modeling wall thicknesses in your Revit file and that is being exported/imported into Openstudio? If you are bringing over spaces with wall thicknesses, that is probably causing you trouble. I think the import process would go smoother if your gbxml/dwg had your spaces modeled with zero wall thickness... like an empty shoe box. If I made the wrong conclusion about how you are modeling in Revit, nevermind. :)

Dear Matthew and Kent, I am so thankful for you. Thank you so much. Dear Kent , You are right . I am modeling wall thicknesses and exporting as rooms in gbXML format.I have to model with zero wall thickness but before exporting gbXML in Revit, It needs to be modeled with wall thicknesses. In modeling Revit, it also is impossible to model zero thickness of building elements .Yours sincerely

When you say you can't import gbXML into OpenStudio, what exactly is happening? Are you getting an error, or does the resulting model just not look like you expect it to? Make sure you are not trying to open it as if it was an OSM. This link shows you how to import a gbXML in the OpenStudio SketchUp Plugin. You can also import gbXML from the file menu in the stand alone OpenStudio application.

Keep in mind that depending upon the Revit workflow you won't necessarily get a clean gbXML, but it would likely be a better starting point than a DWG/DXF. But if you do need to use a DXF this thread has links to videos on modeling from plans or elevations. The same logic is applicable to using a 3d model as a guide.

Dear David, I always really appreciate your help and consideration . Thank you so much again.I used import section in Sketch up options . Now , I have to import it as if it is an OSM. That is why I insist that gbXML is better than DWG/DXF , there is less problem with error in importing model.Yours sincerely
