Defining Measure Probes

Measure Probe tracks distances and angles in a mechanism during a kinematics simulation.

With measure probes, you can:

  • Track the relative distance or angle between two geometric entities.
  • Track the absolute distance traveled by a geometric entity along a specific direction.


Before you begin:

Open a kinematics simulation referencing a mechanism in the Mechanical Systems Experience app. app

  1. Select the Type of measure to track in the probe:
    • Minimum distance tracks the minimum distance or angle between two geometric entities.
    • Measure along a direction tracks the distance traveled by a geometric entity along a specific direction.
  2. Select the Calculation mode:
    • Exact else approximate measures the exact data and provides true values, if possible. If exact values cannot be measured, approximate values are given.

      Note: The Exact else approximate calculation mode is selected by default.
    • Exact measures the exact data, and provides true values.
    • Approximate measures the tessellated objects and provides approximate values (identified by a ~ sign).
  3. In the 3D area or in the tree, select the two geometric entities to use for the probe.

    Note: If you are creating a Measure along a direction probe, the second geometric entity is ignored.

  4. Optional: If you are creating a Measure along a direction probe, specify the measurement direction in the Other Direction box.
  5. To determine the types of values measured by the probe, select the Customize tab.
  6. Click OK to save the measure probe and close the Measure Between dialog box.
  7. Optional: You can preview the probe without saving results by running a simulation preview. The probe values are displayed on the mechanism as you run the preview.
