     DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1 a  shows a window component profile, manufactured using the process of this invention. This preferred embodiment of the window component has three generally elongate sections  101   a ,  101   b ,  101   c  and two half sections  102   a ,  102   b , each connected  113   a ,  113   b ,  113   c ,  113   d  to an adjacent section. In alternative embodiments, when it is desired to have windows with non-rectangular shapes, the number of sections can be increased or reduced. For example, a triangular shaped window may have only two long sections and two half sections. In another example, an octagonal shaped window may have seven long sections and two half sections. The connections  113   a ,  113   b ,  113   c ,  113   d  are flexible permitting a bend at the connection  113   a ,  113   b ,  113   c ,  113   d . The preferred elongate sections  101   a ,  101   b ,  101   c  and half sections  102   a ,  102   b  are preferably made of a composite material, molded, cut, milled, routed or otherwise shaped in to the desired generally decorative shape. While the sections  101   a ,  101   b ,  101   c  are shown, in this embodiment, as being of generally the same length, in alternative embodiments, the sections  101   a ,  101   b ,  101   c  may have different lengths as appropriate to the desired window shape. Each section  101   a ,  101   b ,  101   c  is provided with two diagonal cut sloped portions (respectively  105 ,  106 ;  107 ,  108 ; and  109 ,  110 ). These diagonal cut sloped portions  105 ,  106 ,  107 ,  108 ,  109 ,  110  are shown having an angle of 45 degrees, however, in alternative embodiments this angle may be either increased or decreased as necessary in order to facilitate the joining of two adjacent diagonal sloped portions, to thereby produce a window component having the desired shape. The ends  103  and  112  are, in this embodiment, at approximately 90 degrees from the base  100  of the window portions, thereby facilitating the joining of the ends  103 ,  112 , as shown in FIG. 3 a.    
     FIG. 1 b  shows an alternative window component profile, manufactured using the process of this invention. This second preferred embodiment of the window component has four generally elongate sections  114   a ,  114   b ,  114   c ,  114   d  each connected  116   a ,  116   b ,  116   c  to an adjacent section. In alternative embodiments, when it is desired to have windows with non-rectangular shapes, the number of sections can be increased or reduced. For example, a triangular shaped window may have only three long sections. In another example, an octagonal shaped window may have eight long sections. The connections  116   a ,  116   b ,  116   c  are flexible permitting a bend at the connection  116   a ,  116   b ,  116   c . The preferred elongate sections  114   a ,  114   b ,  114   c ,  114   d  are preferably made of a composite material, molded, cut, milled, routed or otherwise shaped in to the desired generally decorative shape. While the sections  114   a ,  114   b ,  114   c ,  114   d  are shown, in this embodiment, as being of generally the same length, in alternative embodiments the sections  114   a ,  114   b ,  114   c ,  114   d  may have different lengths, as appropriate for the desired window shape. Each section  114   a ,  114   b ,  114   c ,  114   d  is provided with two diagonal cut sloped portions (respectively  115   a ,  115   b ;  115   c ,  115   d ;  115   e ,  115   f ;  115   g ,  115   h ). These diagonal cut sloped portions  115   a ,  115   b ,  115   c ,  115   d ,  115   e ,  115   f ,  115   g ,  115   h  are shown having an angle of 45 degrees, however, in alternative embodiments this angle may be either increased or decreased as necessary in order to facilitate the joining of two adjacent diagonal sloped portions, to thereby produce a window component having the desired shape. The joining of the ends  117 ,  118  are as shown in FIG. 3 b  to form the complete window component. 
     FIG. 2 a  shows a window component profile in the rotational stage of the process of this invention. This view shows the window component of FIG. 1 a , with the diagonal sloped portions  106 ,  107  and  108 ,  109  brought into contact and joined to form corners  201 ,  202  and thereby the bottom  205  of the window component. 
     FIG. 2 b  shows an alternative window component profile in the rotational stage of the process of this invention. This view shows the window component of FIG. 1 b , with the diagonal sloped portions  15   b ,  115   c  and  115   d ,  115   e  brought into contact and joined to form corners  203 ,  204  and thereby the bottom  206  of the window component. 
     FIG. 3 a  shows a completed window component in the final stage ready for installation of the window component of FIG. 1 a . Ends  103  and  112  are connected forming a joint  301  at the top  309  of the window component. Diagonal sloped portions  104 ,  105  and  110 ,  111  are brought into contact and joined to form corners  302  and  303  and to define an interior  307  suitable for holding and retaining glass or other similar transparent or semi-transparent material. The joints  301 ,  311 ,  312 ,  313 ,  314  are typically and preferably made using adhesive, although alternatives such as bolts, screws, pins, clips and the like can be substituted without departing from the concept of this invention. 
     FIG. 3 b  shows a completed window component in the final stage ready for installation of the window component of FIG. 1 b . Ends  117  and  118  are connected forming a joint  315  of the diagonal sloped portions  115   a ,  115   h , thereby forming a corner  304 . Diagonal sloped portions  115   f ,  115   g  are brought into contact and joined to form corner  305  and to define an interior  308  suitable for holding and retaining glass or other similar transparent or semi-transparent material. The joints  315 ,  316 ,  317 ,  318  are typically and preferably made using adhesive, although alternatives such as bolts, screws, pins, clips and the like can be substituted without departing from the concept of this invention. 
     FIG. 4 shows a process flow diagram of the preferred method of this invention. Initially, the material is fed  400  into the assembly process. Next, the material is straight cut  401  preferably by a saw or mill machine. The cut material is set  402  for Lifter or Balance Holding punch, preferably on a drill or router machine. The material is then punched  403  for the lifter clip, also preferably on a drill or router machine. Weep punching  404  is next performed on the material, again typically using a punch, drill or router machine. These punching steps are used to provide ventilation and drainage points in the window component. Miscellaneous processing  405  is performed to remove loose material and/or rough edges. A first three-way cut  405  is made, to produce diagonal portions, preferably using a cutter, grinder, or corner set. A second three-way cut  406  is made, to produce additional diagonal portions, also preferably using a cutter, grinder or corner set. A second weep punch  408  is made to further provide additional drainage and ventilation, preferably using a drill or router machine. A polymer compound is applied  409  to the joint regions thereby providing durable, flexible corners. Identification markings are applied  410  to permit control and tracking of window components. The assembly or window component is rotated with the corner and/or end portions joined together using adhesive, screws, bolts, clips, pins or the like forming the complete window component ready for the insertion of the transparent medium and for installation in the building structure. 
     The described embodiments of this invention are to be considered in all respects only as illustrative and not as restrictive. Although specific steps and window system components are illustrated and described, the invention is not to be limited thereto. The scope of this invention is, therefore, indicated by the claims. All changes, which come within the meaning and range of equivalency of, the claims are to be embraced as being within their scope.
