Re: [TRNSYS-users] Convert a *.b18 file in a *.b17 file

Toni,

 Getting the geometry converted is not too hard. I think all you'd need to do is open SketchUp/Trnsys3d using the appropriate template (*.b18 or *.b17) and then import the resulting *.idf file with the appropriate version of TRNBuild. If you have added a lot of data to the *.b18 in TRNBuild already then things might be a little more difficult. You can export the *.b18 back to an *.idf but I think that TRNBuild from v17 would have a very hard time importing that *.idf to make a *.b17 from it.

 Depending on how brave you are, you could try the following. Import the building geometry into TRNBuild v17 and create a *.b17 file. Open both that file and the *.b18 file using a text compare tool (I use CompareIt) and start moving things from the *.b18 file over to the *.b17  file one piece at a time. TRNBuild's syntax is pretty transparent although there are some definitions (such as the definition of a VENTILATION) that have changed between v17 and v18. You could open another, more complete b17 file using a text editor to see what the syntax looked like in v17.

kind regards,

 David

Hi,

because of problems, we need to convert a building file in format *.b18 in the format *.b17. Is there a fast and easy way to do it? Or we need to reimport from Trnsys3D with Trnsys1 instead of using Trnsys18?

 

Thanks a lot
