In the past I have recreated plenty of rooms digitally. Now I am attempting to digitally recreate some of the rooms on the Titanic. What would be the best software to use to recreate some of the rooms.
It changes with the objective of your work:
if you want to only re-create some of the rooms, you can use AutoCad, it is an architectural program so it is very good for that only when you have mesurements, and his renders are not so beautiful ...
There is also 3d studio max, actually in version 7.0, which is one of the best 3d modelling program but it is also more complicated to use.
