Grid Tool

Use the Grid tool to display the curves that define any face or surface in your design. This tool displays a visual representation of the mathematical expression of the surface. The grid lines represent the mathematical expression used to generate the surface. You can use it to identify a low quality surface. For example, a face may look fine, but the underlying mathematical representation is unnecessarily complicated or poorly parameterized. You would have problems changing the face using other tools.

If you find a face with underlying problems, you can delete the face, then use the Fill tool with the Patch Blend option or the Replace tool to generate a new face.
