I’am using DELFTShip 3.2 Professional without any extensions. When I go to resistence and click tab “appendages” all buttons (rudder, bulb, skeg, etc.) are disabled. My manual have nothing about that.
Is that used for some extension?
Do I need this for my appendages (I am designing a sailboat with keel, bulb and rudder)?
Thanks for any help 🙂
