JT Reader (*.jt)

The interface works in a Reader mode.

  • This is a stand-alone reader which does not require that the JT system be installed.

  • No CAD associativity support.

  • No CAD Parameters support.

This interface can be configured during Ansys Installation or by using the Product & CAD Configuration Manager.

See Product & CAD Configuration Manager for usage information.

Notations

Selective Update  —  This interface does not support the Selective Update feature.

Length Unit  —  The application automatically locks the length unit in the model to millimeters. No adjustment of length unit is necessary or possible. You can change the unit system for display of the Ansys Mechanical application data.

Hidden Parts  —  Parts that are hidden or suppressed are skipped automatically by this interface.

Import CAD Color as an Attribute or Named Selection  —  

  • Attribute: specify the "Attributes" option and set the "Attributes Key" to "Color" or a list of specific Colors delimited by a semicolon (for example: "Color:255.0.0; Color:255.255.0").

  • Named Selection: specify the "Named Selections" option and set the "Named Selections Key" to "Color" or a list of specific Colors delimited by a semicolon (for example: "Color:255.0.0; Color:255.255.0").
