pdnMesh is an automatic mesh generator and solver for Finite Element problems. It will also do post-processing to generate contour plots and Postscr ipt printouts. GUI support using GTK or MFC (Win32) is available. The problem definition can be done

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

读取DXF文件和保存DXF文件,处理通用实体，并且加入了Polygon和Polyface的接口-his is not a complete DXF reader package, but it handles most entities that are commonly found. With this release I ve added the Polygon mesh and Polyface mesh varieties of POLYLINE, so a great
