Dietrichs is not (primarily) an architectural software like ArhiCad, Vectorworks or others. But those software on the other hand are only architectural software, and cannot (I suppose) create machinefiles for CNC kind of machines for timber processing.
So if you are building wooden houses, and you want both worlds (architectural 3D views + 3D timber projects and machinefiles) inside one program - then maybe Dietrichs is a very good choice.
Dietrichs is very strong - the strongest I know and have ever seen - on 3D modelling of timber structures. So accurate, precise and quite easy. And you can make complete house structures including facade finish for 3D views. Only missing for the last issue is a bigger database with doors and windows - if you want to show exactly how the house will look like.
