To Export you don't, it is saved with the PLN or Teamshare file, so from the PLN/TW point the Import button at the File you want to import it from and voila!

Also Solibri Optimizer app is failing to do its optimization to reduce the file size.<BR /> <BR /> Anyone else come across this issue? If you did was there a way to fix it?<BR /> <BR /> Looking at the Translators my Project is using it has only brought in an ArchiCAD 20 translator and it has none of the AC21 presets. The Project was converted from AC20 to 21. <BR /> <BR /> Next problem is there does not seem a way to export the AC21 translators from the AC21 template file and I can't find them on my computer to import them into my Project???</T></DIV> Fri, 18 Aug 2017 09:08:33 GMT https://community.graphisoft.com/t5/Collaboration-with-other/ArchiCAD-21-IFC-export-is-much-slower-than-AC20/m-p/221698#M28354 fuzzytnth3 2017-08-18T09:08:33Z https://community.graphisoft.com/t5/Collaboration-with-other/ArchiCAD-21-IFC-export-is-much-slower-than-AC20/m-p/221699#M28355 Well I have sussed one thing out.
