Hi All, We have been aware that there are some issues plotting from ARCHICAD 20 on a Mac. There is a case in the developer database with the ID #210445. We are planning to fix it in an upcoming update.
There are several workarounds applicable:
1. Use the File > Print... command; or
2. Save a PLT file and print it with an other plotting software; or
3. Save a PLT file and run the following command in the Command Line:
lpr -oraw [plot file name] -P [printer driver name]
Thanks for reporting this issue! Best, k
