How to enlarge the small draft of clay modeling

Multiple ways can be enlarged, the most commonly used are the following:

1, the key point of the three-dimensional coordinates of the calculation method, in the small manuscript under the fixed piece of lattice of the board, the small manuscript to find out a lot of key points, with the level to find out the three-dimensional coordinates of these points, and then preferably draw contour lines in the enlargement of the sculpture in the position on the ground to play a good lattice to find a small manuscript fell to the ground of the key point to enlarge the lattice on the ground Inside, with the angle welded out of a field, the origin of the z-axis stand up to the three coordinate axes as the basis to find out the three-dimensional coordinates of each key point in space, each point with a vertical angle support and make the highest point of the angle fell on the correct coordinates, in turn, connecting the key points, sculpture, sculpture, large shape came out, the finishing process is not necessary to say that, I believe that you understand;

2, the circle, is the small manuscript cut into a number of horizontal and horizontal, the best then draw contour lines, the sculpture is a good location to enlarge the sculpture. Is a small draft cut into many horizontal slices, the top or bottom of each slice of the outline by playing the grid method of enlargement, the three-dimensional conversion to the plane to do the simplified approach, according to the line enlarged out of the ground to bend out of the rebar, as far as possible to make the rebar in the same plane, and then the same axis as the basis for these curved out of the steel according to the calculated distance layer by layer rack, reinforced and reinforcing the connection with the rebar! Between each layer, the big shape came out, and then later, no need to say 。。。。

Other methods do not say it, there are these two will be enough 。。。。
