Core tip: such large stone generally need a model or small model to molding. Now there are two kinds of commonly used copy or amplification technology, is a kind of point, line amplification method, the other is a center for proportion amplification method. Such large stone generally need a model or small model to molding. Now there are two kinds of commonly used copy or amplification technology, is a kind of point, line amplification method, the other is a center for proportion amplification method. Basic this two methods can solve the problem of representational model replication and amplification, but too machinery, stone carving work form are not fully understanding of prototype, stone carving works are often similar to prototype big form and verve. In stone carvings in the practice of using a method of can choose freely grid line is very convenient and can get twice the result with half the effort, can solve the problem of the verve of stone carvings, used the method of stone workers generally reflect the good. Specific steps: first, find out the water at the bottom of the prototype, placed in a row on a grid plate, draw the flat intersection along the prototype bottom line, so that you can put the prototype back again and again, and find cross coordinate the prototype bottom line. Grid line of the vertical space through the best prototype high. Second, the steel square with two parallel to a standard rectangle of about 3 cm on both spacing. Vertically on the tablet, at both steel rule right Angle coordinate online in the same line, let the pencil on the two steel rule, slide up and down, left and right sides, can be very accurate in the prototype of vertical space, in the same way, or so before and after the four vertical found, the last four lines will hand in on a little. Such basic plane coordinates and the spatial coordinates was established. And no matter what kind of twist can draw a vertical line to. Third, freedom of choice on the prototype space coordinate lines and coordinate points, principle is positive with wider mark positive coordinates, line and point; Side profile coordinates, line and point wide outlet. Coordinates, line and point search method and the second step is the same. Pay attention to the positive grid line and side grid line must stagger. . Sunken place also will mark clearly. Four, find out the bottom coordinates on selected stone, and cut out of the plane in time. On the basis of bottom plane, find space coordinates the stone on the line. Using geometric amplification and find out the positive side, the main grid line points, and thought foundation, in the wild. Then disconnect to label the coordinates of clear, continue to look for other coordinates, line and point, and removal of spare parts. Find the coordinates of the line and the more points, more accurate, verve and the closer it gets to the prototype. Five, in order to save Labour, yard work lying on the ground can be processing, mark accurate coordinates, as long as no tangible error problem. Six, the last is the finishing details. The transition and line engraving more smoothly. Then complete the small part of the processing. Enlarged, duplicate, reduced for stone processing, this method is practical, after a practice, you can master the technology. This technology applies to the clay sculpture of reproduction, enlarged and reduced.
