<p class="MsoNormal"><span lang="EN-US">I made a sketchup .idf model that I am using for Trnsys calculations. In TRNBUILD I assigned wall and window types, as well as infiltration heating etc.. Now I want to change my sketchup model because some zones don’t
have the correct boundary assigned (e.g. exterior or adjacent wall) and I want to add an additional zone. </span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">I try to do this by clicking “update TRNSYS3d File” in TRNBUILD. Then I select the corresponding TRNSYS3d File (*_b17.idf)" and save in the second line as TRNSYS3d File (*_update.idf). I then close TRNBUILD and open the

<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Does anyone know what could have happened here. What should I do to avoid this?
</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Is there an alternative way to change the boundary and wall types without changing the sketchup model?</span></p>
<p class="MsoNormal"><span lang="EN-US">Thank you in advance for you answer. </span>
