The great thing about using the midline is that it works for all people and animals from worms to wolves.
All you have to know is the four measurements, radius from given point, length to point, drop in height, depth it material.
The radius is the position on a Circle around the point, measured by a protractor.
The length is just that how far the point is in a strait line, from any given Radial point along the mid-line.
The drop is just how far down from the end of the length line.
The depth is just how far in from the end of the drop line.
This information is the same as used by professional illustrator's and artists since Audubon.
IT is based on work by great artist from the Renaissance which was based on mathematical calculations by Muslim artists in what is now the middle east.
It is century's old.
In Mammals and other animals the mid line would be,
from tip of nose down the back to tip of tail. Then from tip of tail to middle of belly to tip of nose the midline runs alway round the body.
If you find the top you can also locate the belly but becarefull you can get the work to semetrical and it will not look real.bellys should jiggle just a little.
