I have been working on archicad 11 for the last ten years, and finally got a new laptop Lenovo ThinkPad with specs that exceed the requirements for archicad 23 for when I need to upgrade. Can archicad 11 pln files be opened in archicad 23? If not, what is the newest archicad that would still open archicad 11 files? Please advise!<BR /> <BR /> Andre in Scottsdale <EMOJI seq="1f633"></EMOJI></R></DIV> Wed, 08 Jul 2020 00:22:33 GMT blueskyaz 2020-07-08T00:22:33Z https://community.graphisoft.com/t5/Installation-update/Opening-old-versions-of-archicad/m-p/257895#M26942 <DIV class="actalk-migrated-content"><R>Hi All,<BR /> Another question, probably related to my last one.
