– Analysis and arrangement of elements begin with largest and most complex
topology elements. If the library includes elements with various dimensions,
dimension analysis is sufficient; in case of elements with equal geometrical
dimensions, more careful comparison is required;
– Formation of local libraries during recognition of elements in the working field
of the project; these libraries contain the elements that are the most commonly
found in the recognized block;
– Troubleshooting to eliminate errors that occurred after arrangement of elements;
