When i join a company (construction and developer) most the elder senior r using CAD, so u have no choice but to follow the culture. CAD 2010 version add on function like SketchUp, but these elder ppl still using CAD for layout and 3ds max for modeling, which it double the jobs and time consuming and in accurate. For accuracy, simulation and detailing, solid work is the best. Nowadays u can get a software online without installing eg like Leopoly. Majority pay for this industry is peanut, but with workload and overtime... better change your fields before it too later.
