The positioning apparatus is configured to permit the tracing apparatus to traverse along an X-axis, a Y-axis, and a Z-axis and the tracing apparatus is configured to hold a plasma cutter and position the plasma cutter in a plane substantially parallel to a plane defined by a working surface which receives a workpiece to be replicated thereon. ## Claims ### Claim 1 A tracing system, comprising: a positioning apparatus including a frame, a first working surface, and a second working surface, wherein the frame includes a plurality of spaced apart support rails having a movable carriage movably disposed thereon, wherein the movable carriage includes a plurality of spaced apart elongated members extending over the first working surface and a plurality of spaced apart cross-members, each of the cross-members coupled to at least, one of the elongated members and movably disposed on at least one of the support rails, and wherein the first working surface is vertically aligned and vertically spaced from the second working surface; and a tracing apparatus configured to position a working tool in such a manner that the working tool operates in a plane substantially parallel to a plane defined by the first working surface, wherein the tracing apparatus is configured to cooperate with the positioning apparatus to permit the tracing apparatus to traverse along at least throe axes. ### Claim 2 (depends on 1) The tracing system of claim 1, wherein the working tool is a plasma cutter. ### Claim 3 (depends on 1) The tracing system of claim 1, wherein the first working surface is configured to receive a workpiece to be replicated thereon and the second working surface is configured to receive a material from which a replicate of the workpiece is formed. ### Claim 4 (depends on 1) The tracing system of claim 1, wherein the tracing apparatus includes a frame having a stylus assembly and a holding fixture, the holding fixture configured to support the working tool. ### Claim 5 (depends on 1) The tracing system of claim 1, wherein the tracing apparatus is configured to cooperate with the movable carriage of the positioning apparatus to permit the tracing apparatus to traverse along at least one of an X-axis, a Y-axis, and a Z-axis. ### Claim 6 A tracing system, comprising: a positioning apparatus including a movable carriage, a first working surface, and a second working surface, wherein the movable carriage includes a plurality of spaced apart elongated members extending over the first working surface and a plurality of spaced apart cross-members, each of the cross-members coupled to at least one of the elongated members, and wherein the first working surface is vertically aligned and vertically spaced from the second working surface; and a tracing apparatus configured to cooperate with the positioning apparatus, wherein the positioning apparatus is configured to permit the tracing apparatus to traverse along an X-axis, a Y-axis, and a Z-axis, wherein the tracing apparatus includes a first frame having a stylus assembly and a holding fixture configured to support a working tool, wherein the first frame of the tracing apparatus includes a plurality of spaced apart guide members, each of the guide members movably disposed on at least one of the elongated members of the movable carriage, and wherein the tracing apparatus is configured to cause a substantially simultaneous movement of the stylus assembly and the working tool along the X-axis, the Y-axis, and the Z-axis. ### Claim 7 (depends on 6) The tracing system of claim 6, wherein the first working surface is configured to receive a workpiece to be replicated thereon and the second working surface is configured to receive a material from which a replicate of the workpiece is formed. ### Claim 8 (depends on 6) The tracing system of claim 6, wherein the positioning apparatus includes a second frame having at least one support rail coupled thereto. ### Claim 9 (depends on 8) The tracing system of claim 8, wherein the movable carriage cooperates with the at least one support rail. ### Claim 10 (depends on 6) The tracing system of claim 6, wherein the tracing apparatus is configured to cooperate with the movable carriage of the positioning apparatus to permit the tracing apparatus to traverse along at least one of the X-axis, the Y-axis, and the Z-axis. ### Claim 11 A tracing system, comprising: a positioning apparatus including a first frame, a first working surface, and a second working surface disposed substantially parallel to the first working surface, wherein the first frame includes a plurality of spaced apart stationary support rails having a movable carriage movably disposed thereon, wherein the movable carriage includes a plurality of spaced apart elongated members extending over the first working surface and a plurality of spaced apart cross-members, each of the cross-members coupled to at least one of the elongated members and movably disposed on at least one of the stationary support rails, and wherein the first working surface is vertically aligned and vertically spaced from the second working surface; and a tracing apparatus disposed on the positioning apparatus, the tracing apparatus including a second frame having a holding fixture configured to support a working tool, wherein the second frame of the tracing apparatus includes a plurality of spaced apart guide members, each of the guide members movably disposed on at least one of the elongated members of the movable carriage, and wherein the tracing apparatus is configured to cooperate with the movable carriage of the positioning apparatus to permit the tracing apparatus to traverse along at least one of an X-axis, a Y-axis, and a Z-axis. ### Claim 12 (depends on 11) The tracing system of claim 11, wherein the tracing apparatus is configured to position the working tool in such a manner that the working tool operates in a plane substantially parallel to a plane defined by the first working surface. ### Claim 13 (depends on 11) The tracing system of claim 11, wherein the first working surface is configured to receive a workpiece to be replicated thereon. ### Claim 14 (depends on 13) The tracing system of claim 13, wherein the second working surface is configured to receive a material from which a replicate of the workpiece is formed. ### Claim 15 (depends on 1) The tracing system of claim 1, wherein at least one of the spaced apart support rails of the positioning apparatus has a first surface and a second surface formed at an angle of about 90 degrees to each other. ### Claim 16 (depends on 1) The tracing system of claim 1, wherein at least one of the spaced apart elongated members of the movable carriage has a first surface and a second surface formed at an angle of about 90 degrees to each other. ### Claim 17 (depends on 1) The tracing system of claim 1, wherein at least one of the spaced apart cross-members of the movable carriage has a first surface and a second surface formed at an angle of about 90 degrees to each other. ### Claim 18 (depends on 6) The tracing system of claim 6, wherein at least one of the spaced apart guide members of the first frame of the tracing apparatus has a first surface and a second surface formed at an angle of about 90 degrees to each other.
