Tips for AutoCAD Object Data Reading

Note that the AutoCAD Map 3D Object Data 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.

For AutoCAD-to-AutoCAD translations, 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_ENTIY_COLOR = NO

VISIBLE_ATTRIBUTES_AS_TEXT = NO

IGNORE_UCS = YES

PRESERVE_COMPLEX_HATCHES = YES

IGNORE_HIDDEN_LAYERS = NO

EVALUATE_MLINE_GEOM = NO

OD_READING_MODE = od_mode_raw or od_mode_classic

These are also noted on each individual directive description.
