Generating Wrappings

You can generate simplified external representations of 3D shapes.

This functionality lets you select a part or an assembly and wrap it through an additional tessellation to generate a light external envelope of the part. The resulting envelope is a unique volume. It provides a selectable tessellation (grain parameter) which lets you manage the file size against precision of the wrapped representation.

Through this functionality, you can drastically reduce the size of your assembly, roughly reserve room for a component not completely designed as yet and protect the confidentiality of your data while sending information to partners by hiding confidential details of your product.

Before you begin: Open an existing product.

Creating Swept Volumes
  1. From the top bar, select Add > Content.
    The New Content dialog box appears.
  2. In Physical Product Structure, click VOCWrapping .
    The Wrapping dialog box appears.
  3. Select the product for which you want to compute the wrapping, in the tree or in the 3D area.



  4. In the Reference product box, select a reference product.
  5. Enter a value for the Wrapping grain.
    The grain determines the precision of the wrapping representation. The grain parameter determines the size of the triangles used to represent the wrapping. A lower setting results in slower computation time, but a more precise calculation of the wrapping.
  6. Optional: Select the Enable Simplification check box and enter a value for the Accuracy to simplify the wrapping result.
  7. Optional: For improved performance,
    1. Under Envelope, select the Simple option.
    2. In the Offset ratio box, specify a value.
    3. Select the Cubic check box.

      By default, the offset ratio is 0.1 and the Cubic check box is cleared.

    The results are computed using V5 algorithm.
    Note: If the simple envelope type is selected, the quality of the result may be impacted.
  8. Click OK.
    Only surfaces and solids inside the selected product will be taken into account to generate the wrapping. Hidden elements are not taken into account.

    A new 3D shape is created containing the resulting wrapping:
