3D Model Export

Export 3D models.

To export a 3D model, go to the Menu bar and select File > Export > 3D MODEL.
Figure 1.


In the Export 3D Model window there are three Output formats: 3D model, PPT and HTML.
Figure 2.


Both the 3D model and PPT formats support H3D and GLB as model formats, while HTML exclusively accepts H3D in this version.

The options supported for each model format are described in the Options section (below).

H3D

H3D is a compressed binary file format exported from the HyperView client of HyperMesh, containing model, result data, animation and visualization tools.

A HyperView Player in standalone form or embedded inside Microsoft Office is required to open this model format. Please ensure HyperView Player is installed with recommended settings to make embedding work seamlessly. This format provides the richest viewing experience with amount of model attributes and viewing features.

GLB

GLB serves as a three-dimensional file format applied in virtual reality (VR), augmented reality (AR), gaming, and web applications due to its capability to accommodate motion and animation. Notably, its compact size and swift loading times further contribute to its efficacy. GLB files represent a binary version of the GL Transmission Format (glTF).

glTF is a royalty-free specification designed for the efficient transmission and loading of 3D scenes and models within engines and applications. This standard aims to reduce the size of 3D assets and minimize the runtime processing required for their unpacking and utilization.

Numerous GLB viewers are available in the market. The efficacy of the GLB format has been assessed through testing with tools such as 3D Viewer and Microsoft Office applications.

Limitations
The following limitations exist in this release of the GLB feature, however they may be addressed in future releases:
  • Model data such as entities, views, masked entities, sets, and so on that depend on viewer compatibility.
  • Masked elements - if a component is partially shown in HyperView, GLB will show the whole component.
  • Iso, Vector, Tensor plots
  • Feature angle and Variation in averaging method
  • Use corner data option
  • Averaging methods together with MaxLayer, MinLayer and ExtremeLayer are not supported. These features are supported individually.
  • Legend settings like Log interpolation, Min Max, Multiplier, Offset
  • Explosion, Section cut
  • Notes and Measures
  • Tracking systems
  • If there are multiple elements overlapping each other, there may be a wrong representation depending on the viewer.
  • Models for Multibody Dynamics analysis
  • Adaptive mesh in dyna models
  • Eroded elements will be always shown in GLB files unless you hide the full component they come from.
  • Spring dampers

HTML

HTML files are text-based documents housing highly interactive content and are meticulously crafted for digital viewing.

This format stands alone in its capacity to embed both model and viewer within the document, requiring only a compatible browser for seamless viewing.

Browsers supported:
Browser Supported Version or Higher
Chrome 84.0.4147.0
Firefox 78.0.2
Edge 84.0.4147.0
Safari 13.1.1(14609.2.9.1.3)
Limitations
The following limitations exist in this release of the HTML feature, however they may be addressed in future releases:
  • 0D/1D selection graphics
  • Vector, Tensor
  • Systems and Tracking systems
  • Flex bodies, Ellipsoids
  • Note and Measure support. Viewer only supports:
    1. Notes (static text) on node, element, or 3D position in global coordinate system
    2. 2D/3D position notes
    3. Position and Contour measurements
    4. Dynamic Min Max measurement
  • Legend settings - limited settings supported
  • Averaging methods - not supported
  • Deformation/Animation scale - may not be carried to HTML
  • Modal animation type - not supported
  • Explosion, Section cut - Exploded view and Section cuts can be enabled in HTML with global coordinate planes
  • Iso surface – not supported
  • Eroded elements will be always shown in HTML files unless you hide the full component they come from
  • Envelope Derived Load Case for transient models

Options

3D model types compare with H3D in the following way:

Select all options.
Select none.
Reverse selection.
Compression % Suggested amount that the model's values can be perturbed when compressed. The value you provide will be compared to the results of an error estimation function to allow your compression algorithm to maintain an acceptable level of accuracy for your data. However, even a percentage of zero may result in some loss due to minute rounding errors. Higher percentage values may yield unacceptable models, depending on model geometry and result values.
All models Export all the models in the window to individual files when two or more models are loaded. The active model will be exported to the file name shown in the dialog. All inactive models will be exported using the following naming convention: <filename>.x.h3d, where "x" increases incrementally as required. For example, the active model is exported as LSP.h3d, while the other (inactive) models will be exported as LSP.1.h3d, LSP.2.h3d, and so on. (The resulting exported H3D files are complete files which can be used independently. These files can be abstracted from the original session that exported them and used in a new session. To read the exported files back into HyperView they must be loaded one file at a time using the Overlay option in the Load Model panel.)
Entity Attributes Output specific attributes assigned to the model entities, such as color and transparency. If deselected, the default attributes will be used when the file is loaded.
View Attributes Output the View definitions created in HyperView window. If deselected, the default view attributes will be used when the file is loaded.
Masked Elements Export all masked elements with the model. They will remain masked when the file is loaded.
Sets Export all sets with the model.
Animation Export any animation settings applied.
Results Export result values with the model. If not selected, only the model and animation are exported.
Preview Image Export a preview image.
Open after export The exported file is automatically opened after exporting.
