Split, Swap, Combine Elements

Use the Edit: Split tool to split quad elements and edges, combine tria elements, and swap element edges.

The Edit tools work for tessellated geometry. If the input is b-spline geometry, first convert to discrete geometry using the Convert tool.
  1. From the Geometry ribbon, click the Edit > Split tool.

    Elements are colored according to how well they adhere to the pre-set quality requirements defined in the criteria file.
  2. Optional: On the guide bar, click to to define the options used to edit elements.
  3. Select an element issue type from the guide bar.
    Quality
    Checks for quality as defined in quality criteria.

  4. Optional: Find all elements at or below a certain quality level.
    1. Click Find on the guide bar.
    2. Increase or decrease the number of layers around patches of failed elements by clicking or on the guide bar.
    3. Review the next or previous patch of failed elements by clicking or on the guide bar.
