browsing the site autodesk I saw another program, building design, I did not understand well the differences from revit architecture, what I think I understood is that the interface and basic icomandi are the same, but the first allows to do many more things, such as rendering, structural calculation, calculation energy saving, etc.
Do I understand?
Not really. the building design suite is a solution formed by multiple products such as autocad, revit, 3ds max design so much to make known names, it is not a single application.
the concept is still correct. with the suite you have all the necessary tools to design with the capital p. the ultimate bds, the top of the range, also contemplates robots for structural calculation to finite elements and inventor for digital prototyping. and the interesting thing is that the cost, given the number of applications, is quite contained.
