Every program has its measures , using mm or inches, but when we start modeling no matter the 3D program, we just start ,nobody really pays much attention to the measures.
I use to scale my objects in the 3D program, and load it into Dbpro, because if we scale too much our models, could be affected by the lights in Dbpro. Of course, I can scale a bit but if I need for example a house, and into Dbpro it looks like a box of 5*5*5, then I export again with a bigger size.
