Hi,
I was also surprised there is no more a task for timber design. You make timber design in teddy task. For info I suggest you press F1 for help when in teddy task and the appropriate manual will open. Also you have teddy example in C:\Program Files\SOFiSTiK\2020\SOFiSTiK 2020\aqb.dat\english\aqb1_3_timber_design.
Sofistik is not so user friendly software but once you get used to it, you dont want anything else.
+PROG AQB urs:12.1
HEAD timber design
ECHO val extr $how long report you want
lc 1 type (pt) $which loadcase and the duration

END
Also you should upload ssd and dwg file for other answers.
