<body class='hmmessage'><div dir='ltr'>I created a new TRNSYS project with a 3d multizone building and the simulation runs with no issues. I then modified the building in TRNBuild and saved it under a different name. When I change to the new building (*.b17 file) in Simulation Studio by altering the path in the "External Files" section of the Building Type, Simulation Studio crashes. <br><br>The error message reads "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."<br><br>The strange thing is that this happens even if I select the same *.b17 file that was being used originally i.e. going into "External Files" and selecting the same file that is already loaded and working properly.<br><br>I am just wondering if anyone else has had a similar problem, or knows where I should start troubleshooting.<br><br>I have tested with one of the example building projects and there is no problem there which would lead me to believe that there is some problem either with the *.idf file or the *.b17 file. However, this doesn't seem to be the case as the simulations run without a problem. I have attached both of these files.<br><br><br> </div></body>
