Another question, probably related to my last one. 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!
