The JT reader uses the jt_reader.ini file with the following available options:

 

@ApplyLayerFilters

Value

Description

string

Import only the specified layer filters.

The string should be in the form of "%filter1%filter2%filter3". The filter names are listed, separated by a character that you choose, and inserted as the first element of the string. The example uses '%' as a separator. You can choose another character as a separator, in case one of the listed attribute names contains '%'. HyperMesh will recognize it as it is the first character of the string.  A special value of DEFAULT can be used to indicate the default layer filter.

 

@AttributesAsMetadata

Value

Description

on

Import all generic attributes (global and related to single entities) as metadata.

<name>

off

Do not import generic attributes.

part

Import just the global attributes (the attributes related to the part as a whole) as metadata.

<name>

entity

Import just the entity attributes (the attributes related to single entities) as metadata.

<name>

%attribute1%attribute2%attribute3

Import specified generic attributes as metadata.

The attribute names are listed, separated by a character that you choose, and inserted as the first element of the string. The example uses '%' as a separator. You can choose another character as a separator, in case one of the listed attribute names contains '%'. HyperMesh will recognize it as it is the first character of the string.

<name>

 

@BrepAndTessLoadOption

Value

Description

0

Import B-rep or tessellation, with B-rep given preference. If B-rep is present, tessellation is not imported (default).

1

Import both the B-rep and the tessellation.

2

Import only the B-rep. If B-rep is not present, nothing is imported.

3

Import only the tessellation. If tessellation is not present, nothing is imported.

 

@CleanupTol

Value

Description

double

A negative value (default) means to use the auto cleanup tolerance.  A value greater than the calculated auto cleanup tolerance means to use that specific tolerance.

Refer to the CAD Cleanup Tolerance section.

 

@ColorsAsMetadata

Value

Description

on

Read color attributes of geometric entities as metadata.

COLOR_RGB

off

Do not read color attributes (default).

 

@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).

 

@FilterByJTOpenParts

Value

Description

string

Import only the specified parts.

The string should be in the form of "%part1%part2%part3". The part names are listed, separated by a character that you choose, and inserted as the first element of the string. The example uses '%' as a separator. You can choose another character as a separator, in case one of the listed attribute names contains '%'. Engineering Solutions will recognize it as it is the first character of the string.

 

@ImportForVisualizationOnly

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

Import the model in the normal fashion (default).

 

@ImportFreeCurves

Value

Description

on

Import free curves (wireframe entities) into the model (default).

off

Do not import free curves.

 

@ImportFreePoints

Value

Description

on

Import free points into the model (default).

off

Do not import free points.

 

@MaterialName

Value

Description

string

Name of the CAD attribute containing the material name info of the current part. Default is "P_MAT"; meaningful only if @AttributesAsMetadata = "part". It only generates temporary data used by the ExtAPI cadassm tool.

 

@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.

 

@PartNumber

Value

Description

string

Name of the CAD attribute containing the part number info of the current part. Default is "DB_PART_NO"; meaningful only if @AttributesAsMetadata = "part". It only generates temporary data used by the ExtAPI cadassm tool.

 

@SkipCreationOfSolid

Value

Description

on

Read surfaces, but do not create solid entities.

off

Create solid entities (default).

 

@SplitPeriodicFaces

Value

Description

on

Split periodic surfaces to improve the quality and robustness of the import (default).

off

Import periodic surfaces as a single surface with a seam edge.

 

@TagsAsMetadata

Value

Description

on

Create entity name as metadata (default).

TAG

FromBody

Take entity from its parent body and create it as metadata.

TAG

off

Do not read tags.

 

@ThicknessName

Value

Description

string

Name of the CAD attribute containing the thickness info of the current part. Default is "P_GAUGE"; meaningful only if @AttributesAsMetadata = "part". It only generates temporary data used by the ExtAPI cadassm tool.

 

@UID

Value

Description

string

Name of the CAD attribute containing the UID info of the current part.

Default is "UID"; meaningful only if @AttributesAsMetadata = "part". It only generates temporary data used by the ExtAPI cadassm tool.
