API, Reference Guides
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
- Python API
  The Python API documentation for HyperMesh applications.
- Tcl/Tk Commands
  The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
  - Program with APIs for Beginners
    APIs can be used to perform various actions in an application. For example, the AddPage API can be used to add a page within the project.
  - Object Hierarchy
    Overview of object hierarchy for HyperView, HyperGraph, HyperMesh, MotionView, MediaView and TextView.
  - Tcl/Tk Classes
    Links to the introductory pages for the Tcl/Tk commands that can be used in HyperView, MotionView, HyperGraph, HyperGraph 3D, TextView and MediaView.

hwIH3DExportOptions GetWriteDisplayedComponents

Queries whether only visible components will be written.

Syntax

hwIH3DExportOptions_handle GetWriteDisplayedComponents

Application

Tcl Query

Description

Returns true or false, depending on whether writing displayed components only is enabled.

Sometimes, only part of a model is of interest. The remainder of the model can then be rendered invisible by turing off components. In some cases, it is desireable to write out only the remaining portion of the model and the related results.

Example

To check if only displayed components will be written:

hwi GetSessionHandle mySessionName
mySessionName GetH3DExportOptionsHandle option_handle
options_handle GetWriteDisplayedComponents

Errors

None.
