Design Toolbox is a collection of tools designed to accelerate and simplify basic modeling tasks of architectural, urban or interior scenes tools: Standard transformations by reference, like the ones usually found in more precise work oriented applications; Fast measurements, speed up positioning of reference coordinates and workplanes. It also includes some other useful tools for quickly apply and manipulate uvw maps, for paneling simple surfaces; plus some others useful time saver tools.
