The drawings in the description are part of the description. Deleting the drawings in the description is equivalent to modifying the description. Generally speaking, it is impossible for the examiner to allow such an operation.
In addition, there are usually reference marks in the drawings of the description. Deleting the drawings will easily lead to insufficient disclosure of the contents of the description, and it is also easy to change the serial numbers of the drawings later. Therefore, It is difficult for the examiner to agree to such an operation as deleting the instructions and drawings.
