Supported Entities

Entities supported by the IFC reader: Faceted B-rep geometry.

Import Options

@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 Import Options.
@CreationType
Value Description
Parts Generate a full part-based hierarchy.
BOMOnly Generate an empty part-based hierarchy.
PackIntoSinglePart Consolidate hierarchy into a single part.
@DoNotMergeEdges
Value Description
on Preserve the original geometry edges, instead of merging them together during the import cleanup phase.
off Merge edges together during the import cleanup phase (default).
@DisplayRepresentation
Value Description
on Import the model for visualization purposes only.

This skips many of the import steps (cleanup, stitching, solid creation, and so on) to provide a faster import. The resulting model may not be suitable for other uses.

off In batch mode, this corresponds to the NX Part browser Layer filtering selection (default).

In GUI import when Creation type is set to Assemblies, this initializes the corresponding option in the NX Part browser.

@ScaleFactor
Value Description
double Define the model scaling factor during import.

Default is 1.0.

@SkipCreationOfSolid
Value Description
on Read surfaces, but do not create solid entities.
off Create solid entities (default).
@SplitComponents
Value Description
Body Generate body-based component (default if CreationType=Parts).
Part Generate part-based component.
@StitchingAcrossBodies
Value Description
on Stitch surfaces belonging to different components.
off Do not stitch surfaces belonging to different components (default).
@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.
MMKNMS [mm kg kN ms] Convert to the corresponding units system.
MMGNMS [mm g N ms] Convert to the corresponding units system.
IPS Std [in pounds lbf 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).
