They didn't get very far with anything more realistic. A lot of the plans and policies were caused by the development of the war. Hitler himself was not an economist. His background was art and military. His hobby was city architecture and military strategy... A large scale area in Eastern Europe was dreamed about (-> upto 1933) and in 1939 the war started with the attack on Poland to realize this war for Lebensraum, where the Germans then would be the elite race and the others were slaves (or dead). This east european region would provide food, energy, raw materials, ... There were ideas about what this large "Reich" would be like. But that was not close to be realized, given that Germany was deeper in war with every day, on two sides, 1941 onwards: in the east in the Soviet Union and against a US lead war in the west. Germany was busy fighting the war. 43/44 some German economist were beginning design an economy in more detail for a time after a war. But it then became clear that it was after a lost war (with the Nazis no longer in power) and that this time probably was not far away, with then the war being lost in 1945.
