Description

DVread_dfx reads in ASCII DXF formatted files and outputs an unstructured mesh. There may be cell data depending on the contents of the DFX file. DFX is an AutoCAD Drawing Interchange File format, created by AutoCAD developers to represent 2D and 3D models.DXF Only a subset of the DXF is supported. This subset includes LINE, 3DLINE, 3DFACE, POINT, and POLYLINE/VERTEX. The reader does support polymeshes and polyfaces, however, closed polymeshes are not handled correctly. There is limited color handling - it knows about only the predefined colors 0 - 9. There is no support for BLOCK, INSERT or LAYER.

Note that the DXF reader at the IAC accepts a larger subset of the DXF format.
