Tried DWG-s but as it seems then theres no 3D. Basically its just that the file could be opened in Archicad 16 for viewing in 2D and 3D. Editing is not even needed. Getting an message "Non Autodesk DWG" in TrueView - with what setting should the DWG created in AC19 ?</T></DIV> Thu, 28 Jan 2016 12:36:15 GMT https://community.graphisoft.com/t5/Collaboration-with-other/From-ArchiCad-19-to-ArchiCad-16/m-p/253663#M33108 Anonymous 2016-01-28T12:36:15Z https://community.graphisoft.com/t5/Collaboration-with-other/From-ArchiCad-19-to-ArchiCad-16/m-p/253664#M33109 dnbforces:<BR /> <BR /> Unfortunately, in AC19 you will need to Save As... AC 18 Project, then open that file in AC 18 and Save As... AC 17 Project, then open that file in AC 17 and Save As... AC 16 Project. New features will be dropped as you go backwards.

I thought that it might be such a pain to get it backwards compatible.<BR /> <BR /> Would it be possible to create DWG then what has 2D and 3D views and would be possible ti view with DWG TrueView or with that online version? I went through all the settings but without any luck.

For a walk-through 3D Model, try saving the AC file in the BIMx format. With BIMx Pro, layouts can be added to the file.<BR /> 2. The other user can install AC 19 without a license. They can open and view the file in Demo Mode, but will not be able to save.<BR /> 3. Save the file as DWG from the 3D Window, then the other user can open that file as an Object. It will be a single object of the entire model.<BR /> <BR /> David Fri, 29 Jan 2016 13:55:15 GMT https://community.graphisoft.com/t5/Collaboration-with-other/From-ArchiCad-19-to-ArchiCad-16/m-p/253668#M33113 David Maudlin 2016-01-29T13:55:15Z
