Time-Based ODS Demo

  1. Hover the mouse pointer over the Demos tab to display the Demos Fly Out Panel.

  2. Make sure the Help | Show Tool Tips is checked.

  3. Position the mouse pointer over the panel to display the Antenna.VTprj Project name, and double click to open the Project.

  4. Execute Draw | Animate Shapes in the Structure (STR) window.

Demos Tab With Mouse Over Antenna.VTprj.

Sweep Animation will begin using shape data from a Data Block on the left with four M#s in it.  Notice that a Line cursor (vertical red line) is sweeping through the M#s in the Data Block window.  The model is being deformed by the ODS (M# data) at the cursor position.

Changing the Animation Speed

The animation may be too fast or too slow, depending on the speed of your computer.  To change the animation speed,

  1. Click on the Structure window Title bar to make it active.

  2. Hover the mouse pointer over the Structure window Toolbar to display the Tool tips.

  3. Locate the Animate | Speed | Increase Speed (rabbit) and Animate | Speed | Decrease Speed (turtle) Tools on either side of the Animation Method Tools .

  4. Click on the Turtle Tool to decrease the animation speed.  Click on the Rabbit Tool to increase the speed.

Quad View versus Single View

The Structure window can display a single View of the structure model, or four Views together in a Quad View format.

  1. 3D View (upper right quadrant).

  2. Z Axis View (upper left quadrant).

  3. X Axis View (lower left quadrant).

  4. Y Axis View (lower right quadrant).

When the Vertical Axis is changed on the Display tab in the File | Structure Options box, the labeling of the three 2D Views will also change.

To change between the Quad View and one of the four Views,

Active View

When the Structure window is in Quad View, the active View is indicated by the yellow box in the Display | View button.

Interpolated Motion

The deformation of the Antenna structure model is being created using data from only four Traces in the Data Block window.  Without interpolation, these four points (the numbered points on the 3D model) would be the only ones moving during animation.  Most of the points on the model are unmeasured points, but they are moving also.  The motion of each unmeasured point is being interpolated from the motions of nearby measured points.

Notice that with interpolation enabled, the cantilevered motion of the model is influenced by of the motions of the four Measured DOFs, plus the influence of Fixed DOFs at the base of the antenna.
