JT Export Options

The JT export option is extensively used inside CAD modeling and PLM systems to quickly visualize a products structure and to compare changes between revisions of CAD and FE models. Select the JT export option to export all of the model's geometry and FE element information, component organization, and property color.

The JT writer uses the jt_writer.ini file with the following available options:

 

@AllowDisjointShells

Value

Description

on

Store non-manifold geometry in one disjoint feature.

off

Split and store non-manifold geometries as separate joint shell features (default).

 

@AssemblyMode

Value

Description

flatten

Write entities in all components into a single component.

hierarchy

Single level assembly with each component as a child (default).

 

@CreateTessellation

Value

Description

on

Create tessellations even when no mesh is exported (default).

off

Create just the tessellations corresponding to the exported mesh.

 

@Export

Value

Description

all

Export all geometry (default).

displayed

Export displayed geometry only.

 

@FileMode

Value

Description

Monolithic

Create a single JT file.

PerPart

Create a JT file “Per part”.

For example, there is a JT file containing the main assembly and each part is stored in an individual JT file in a subdirectory with the same name as the main JT file (default).

 

@GeometryMode

Value

Description

Standard

Write CAD geometry with standard types such as cylinder, cone, circle, and so on (default).

BSpline

Convert all surface geometry data into NURBS. This option may increase the output file size and be time consuming depending on the actual geometry.

 

@MetadataPrefixFilter

Value

Description

string

The prefix to use to find metadata to export. Only metadata with the specified prefix is exported. Any metadata without this prefix is not exported.  Default is empty, meaning all metadata will be exported.

 

@OptimizeForCAD

Value

Description

on

Fix gaps between stitched edges and vertices to make the actual geometry of the surfaces consistent with the model topology before export, and check the topology of the model for gaps that are larger than a given tolerance between shared, non-manifold, or suppressed edges. If the gap is found to be bigger than the tolerance, the surface and edge geometries are morphed parametrically and in 3D, if necessary, to make the gap smaller than the tolerance. In addition, non-essential degenerate edges are removed.  This also modifies the geometry within HyperMesh (default).

off

Do not perform the optimization steps.

 

@RemoveMetadataPrefix

Value

Description

on

Remove the metadata prefix for export.

Meaningful only if @MetadataPrefixFilter is enabled and non-empty.

off

Do not remove the metadata prefix for export (default).

Meaningful only if @MetadataPrefixFilter is enabled and non-empty.

 

@TopologyMode

Value

Description

Solid/Shell

Export topology data similar to HyperMesh topology data, keeping the distinction between solids and shells (default).

Surface

Export each surface, including solid faces, as a single surfaces, effectively neglecting connectivity.

 

@Units

Value

Description

Microns

Millimeters

Centimeters

Meters

Kilometers

Microinches

Inches

Feet

The unit system to use for export. JT stores data in millimeters only.  This value is taken as the existing unit system and all values are converted from this system into millimeters.

 

@Version

Value

Description

string

The JT version to use for export.  Valid versions are 9.5 (default), 9.4, 9.3, 9.2, 9.1, 9.0, 8.1, 8.1, 8.0, 7.0 or 6.4.

 

@WriteColorFrom

Value

Description

string

Specify colors for the geometrical entities during export.  Colors are supported at the component level only, whereas individual entity colors (points, lines, surfaces, solids) are not supported.

Valid values are Component (default) and Metadata.

 

@WriteMetaDataAsColor

Value

Description

string

Specifies the metadata to use for coloring entities.

Default is COLOR_RGB.

Meaningful only if @WriteColorFrom = "Metadata".

 

@WriteMetaDataAsName

Value

Description

string

Specifies the metadata to use for naming entities.

Default is TAG.

Meaningful only if @WriteNameFrom = "Metadata".

 

@WriteNameFrom

Value

Description

string

Specify names for the geometrical entities during export. Names are supported at the component level only, whereas individual entity names (points, lines, surfaces, solids) are not supported.

Valid values are Component and Metadata (default).
