A variety of new tools are available to review the mesh and to identify areas of the mesh that need to be improved. These enhancements are available in part and sheet metal, but they are particularly useful in an assembly model.
A new Show mesh on Close option in the Mesh dialog box enables you to display the mesh independently of the Mesh command.
Check boxes under the Mesh node in the Simulation tree-view pane show and hide the mesh on individual parts.
Example:
While the mesh is displayed, you can use the new Show Poor Quality shortcut command to locate areas of poor mesh quality.
After you apply sizing to those areas, you can use the new Remesh command in an assembly model to mesh just the affected part.
