ThanCad 0.9.2 "Tartu": n-dimensional CAD with raster support for engineers

This package emulates the dxf library in ThanCad.

Extensions to the dxf format.

These are needed because of the dreadful and unnecessary complexity of the
dxf format.
THANCADSPECIFIC: Extensions specific to ThanCad:
                 Nested layers
                 More layer attributes
THANINTELLICAD:  Extensions which, if present, do not cause
                 intellicad to complain
THANCAD:         ThanCad is able to cope with all extensions
