Re: [TRNSYS-users] Transferring aTrnsys3d Sketch Up to Transys

Nicholas,

Regarding the first error message, it is a problem of unmatching surfaces.

When you drew your different thermal zones with the Trnsys3d wizard in SketchUp you probably used at the end the surface matching button.
This button calls for a function which scans all the surfaces included in your project and affects a construction type (for instance ground floor, ext_wall, adj_wall, …). In case of adjacent walls the outside boundary condition (you can see this property in Trnsys3d > Object info when right clicking on a surface) must be “zone”, and the Outside boundary object must be another zone name. The surface matching button works pretty well as long as surfaces match exactly. But when one wall of zone A is simultaneously adjacent to one wall of zones B and C then you have to manually split the wall of zone A into two walls respectively adjacent only to zone B and only to zone C. Otherwise the adjacent wall won’t be automatically addressed when using the surface matching button. That is probably what happened in your project.

You must then re-open your *.idf file in SketchUp and check all surfaces of zones reported in the error message with the object info window to see if an adjacent surface is defined for each surface of the zones. This is probably not the case.

I would say the second error message might be a logical consequence of the first one.
I can't properly read the third one (the resolution is too low) but if you fix the first problem it might also fixed also the last one…?

Hello Everyone,

So I am working on a 2 zoned Transys House in Google Sketch up and when I try to import it into Simulation Studio using the 3D Building Project Wizard the following happens.

I go to open the IDF file I generated in sketch up and the attached 3 error screen pop up in order (1,2,3). 

I have no idea what Im doing wrong and I am the first student that I know that has tried this. I am basically at a dead end. 

I have also included my sketch up model IDF file because that is most likely where the error lies.

Thanks in advance if someone can help with this!
