Scope of application

The interplay of technology and design for the perfect window

By entering just a few parameters you can design the frames and fillings of your doors and windows. Relevant parameters are for example: Size, corner connections with or without glass beads, fittings and much more. With the click of the mouse, the window will be broken down in seconds to individual CNC programs. Without any extra work, the machine operator can then load these files from the production planning and run them. A material list will be automatically generated with the image of the window.
