+\note <b>Shape Processing</b> is useful not only on invalid shapes,
+ but also on the shapes, that are classified as valid by
+ the <b>Check</b> functionality. Use it, if an operation (for
+ example, <b>Partition</b>) fails.
+ Example of usage:
+ <ol>
+ <li>Try to partition objects obj1 and obj2.</li>
+ <li>Partition fails.</li>
+ <li>Perform Shape Processing on objects obj1 and obj2.</li>
+ <li>Try to partition them again.</li>
+ </ol>
