Tip: Tip: The AutoCAD reader automatically determines whether the file is DWG or DXF and processes it accordingly. Therefore, the same mapping file can be used to read either DXF or DWG.
Note: The AutoCAD reader directives list defaults that will produce the best generic result to any non-AutoCAD destination format, resulting in the best presentation at the cost of some of the original AutoCAD types being lost. For example, blocks and dimensions will be resolved into their component parts. If an AutoCAD-to-AutoCAD translation is desired, the following set of options should be used for best preservation of the original drawing.
STORE_BULGE_INFO = YES
STORE_SPLINE_DEFS = YES
RESOLVE_BLOCKS = NO
RESOLVE_DIMENSIONS = NO
RESOLVE-ENTITY_COLOR = NO
VISIBLE_ATTRIBUTES_AS_TEXT = NO
IGNORE_UCS = YES
PRESERVE_COMPLEX_HATCHES = YES
IGNORE_HIDDEN_LAYERS = NO
INTERPRET_EXTENDED_DATA = NO
EVALUATE_MLINE_GEOM = NO
These are also noted on each individual directive description.
