Command: importDXF
Description:
Imports a DXF file. It has to be noted that the used drawing scale and
natural unit are not defined in DXF. Therefore the user is responsible for
the correct specification of these two parameters.
The correct drawing scale has to be
specified in advance by the user. The natural unit has to be specified
interactively by the user. This value can be different from the actual
natural units defined in the database.
It should be noted that the current drawing is not automatically cleared
before the import. The DXF data is added to the drawing.
From the TABLES section the STYLE, LTYPE and LAYER tables are
imported to CADEMIA.
From the ENTITIES section the following types are imported into
CADEMIA: ARC, ATTDEF, ATTRIB, CIRCLE, DIMENSION, ELLIPSE, HATCH, INSERT,
LINE, LWPOLYLINE, MTEXT, POLYLINE, SOLID, TEXT and VERTEX. INSERTs are
resolved from the referenced block in the BLOCKS section and are
represented as groups.
All other entity types are skipped. ImportDXF keeps track of the imported
entities and shows a report at the end of the command.
DXF distinguishes between model and paper space. CADEMIA contains a model
space but not a paper space. ImportDXF yields best results for entities
stored in DXF model space. The user can define how paper space entities
should be handled: They can be ignored or they can be imported to CADEMIA,
the latter often yielding suboptimal results.
