The following is a description of the Frame Widths page of the Graphical Interface Panel of Window Settings, for a window in the INT ArchiCAD Library.
Use this tab page to set the frame width(s) for the window structure.
If Uniform Frame Width is checked (either on this tab page, or on the Frame and Sash tab page), then you set a single width value for all sides of the frame.
If you uncheck Uniform Frame Width, you can set varying width values for the sides, (as for a complex-shaped window).
