The technology of building component parametric provides you with a far more efficient method for construction planning than you could ever have thought possible by solely using drawing functions. You can, for example a plot detail, or change a window division numerically or graphically, and this change can then be transferred to a selection of other windows. It is so easy to use that you will quickly benefit from it. This does not only apply to windows; but doors, walls, roofs, ceilings, stairs, etc. are also available parametrically.
