Hello, can I ask. Is it possible to somehow export a DWG file from autocad 2019 to archicad 21?
ArchiCAD will open the same AutoCAD versions that it will Save As. Which for ArchiCAD 21 is AutoCAD 2013 back to 2000. And for ArchiCAD 22 is 2018 and back to 2000.
I just confirmed that with the AutoCAD 2020 demo version.
I think it is interesting that Vectorworks can export or open (25) different AutoCAD versions from AutoCAD 2019 all the way back to version 12.
