Creating Swept Volumes

Swept Volume allows you to create swept volumes that collectively plot the position of the selected part at each step of the simulation.


Before you begin:
  • Generate the scenario results of a kinematics simulation to have them appear under the Result node.
  • Make sure the scenario result that you want to trace is the current one. To set the scenario result as the current one, right-click it and select Set as Current.
  1. In the tree, select a scenario result.
  2. To select the elements to sweep, do one of the following:
    • To select individual elements from the scenario result, select the elements in the tree.
    • To select individual elements from the scenario result, click the icon next to the Element(s) to sweep field, and select the elements.
    • To select all moving elements from the scenario result, in the Sweep All area of the dialog box, select Sweep all moving products.
  3. Optional: Select the Reference product. By default, the main product is selected in Reference product.
  4. Optional: To interpolate the mechanism positions, select Filter Positions, and enter the maximum distance between positions in Filtering precision.

    Although the kinematics animation includes mechanism positions for only discrete time increments, the volume sweep can interpolate the positions of the mechanism between these increments to generate a smoother shape.

  5. Optional: To prevent interpolation of the mechanism positions, clear Filter Positions.
  6. To create an envelope around the selected parts, select Enable Wrapping, and enter a grain value in Wrapping grain .
  7. To simplify the representation of the selected parts, select Enable simplification, and enter an accuracy value.

    Important: The simplification is available only if Enable Wrapping is selected.

  8. Click OK.
    The swept volume opens in a new tab. In the kinematics simulation tab, Swept Volume is created under the current scenario result.
  9. To display an existing swept volume, right-click the swept volume representation in the tree, and select Display Representation.
  10. To update a swept volume, right-click the swept volume in the tree and do either of the following:
    • Select Update to update not only the scenario and its results, but also the products and assemblies. It may be time consuming, especially for large models.
    • Select Local Update to only update the scenario and the selected post-processing (swept volumes).

    Note: Alternatively, use the Computation and Generate Results commands (local or global update) to update swept volumes.

    The swept volume opens in a new tab. In the Mechanical Systems Experience tab, Swept Volume is updated.
