To Create Position, Velocity, or Acceleration Measures

1. Click Measures. The Measure Results dialog box opens.

2. Click . The Measure Definition dialog box opens.

3. Type a descriptive name for your measure, or accept the default name.

4. Select a Type

:

◦ Position

◦ Velocity

◦ Acceleration

5. Select the point or motion axis in your assembly for which you want to define a measure. After you select the motion axis or select the point and a component, a shaded arrow appears on your model indicating the direction of the vector.

6. If you select a point, use the arrow button in the coordinate system area to select a coordinate system. The default coordinate system is the WCS. You can also select an LCS or UCS.

7. If you select a point, select one of these components to measure:

◦ Magnitude—magnitude of the position, velocity, or acceleration vector

◦ X-component—X component in the selected coordinate system

◦ Y-component—Y component in the selected coordinate system

◦ Z-component—Z component in the selected coordinate system

8. Select an evaluation method

:

◦ Each time step

◦ Maximum

◦ Minimum

◦ Integral

◦ Average

◦ Root mean square

◦ At time

9. If you select At time, enter a real-number value greater than zero in the Time entry box.

10. Click OK.

11. Graph the measure.
