Import Options

The DXF reader uses the dxf_reader.ini file.
@BodyIdAsMetadata
Value Description
on Assign body identifier as metadata.

BODY_ID
off Do not assign body identifier as metadata (default).
@CleanupTol
Value Description
double A negative value (default) indicates to use the auto cleanup tolerance. A value greater than the calculated auto cleanup tolerance indicates to use that specific tolerance. Refer to the CAD Cleanup Tolerance.
@ColorsAsMetadata
Value Description
integer

Read color attributes of geometric entities as metadata with integer values.

COLOR_RGB
on

Read color attributes of geometric entities as metadata.

COLOR_RGB
off Do not read color attributes (default).
@CreationType
Value Description
Parts Generate a full part-based hierarchy.
BOMOnly Generate an empty part-based hierarchy.
TreeOfComponents Generate an assemblies/components based hierarchy.
PackIntoSinglePart Consolidate hierarchy into a single part.
@LegacyHierarchyAsMetadata
Value Description
on Generate metadata with the original CAD hierarchy within the part.

LEGACY_HIERARCHY
off Do not generate metadata with the original CAD hierarchy within the part (default).
@MetadataPrefix
Value Description
string The string is prefixed to all metadata names. No prefix is used by default.

See CAD Metadata Naming for more details.
@ScaleFactor
Value Description
double Define the model scaling factor during import.

Default is 1.0.
@SplitComponents
Value Description
Part Generate part-based component (only allowed value if CreationType=Parts).
General Keep component as in CAD (only allowed value if CreationType=TreeOfComponents).
@TargetUnits
Value Description
CAD units Keep the units of the CAD files (default for GUI).
MKS [m kg N s] Convert to the corresponding units system.
MMKS [mm kg N s] Convert to the corresponding units system.
MPA [mm t N s] Convert to the corresponding units system.
CGS [cm g dyn s] Convert to the corresponding units system.

IPS Grav [in slinch lbf s] Convert to the corresponding units system.
FPS Std [ft pounds lbf s] Convert to the corresponding units system.
FPS Grav [ft slug lbf s] Convert to the corresponding units system.
Scale factor Apply the corresponding scale factor (default for no GUI to allow supporting legacy scripts).
