MIL-HDBK-115 Us Army Reverse Engineering Handbook Guidelines And ProceduresThis HANDBOOK, which provides the guidelines and procedures for performing reverse engineering, was created using current applicable laws and knowledge gained during a trial program from July 1985 to April 1987, and is based on experiences obtained from military and industry participants. This handbook is for guidance only and cannot be cited as a requirement.

NOTE: MIL-STD-31000 may be used as guidance concerning engineering drawings and definitions.

5.25.5 Drawing media. Level 3 drawings should be prepared on the media and formatted specified by the cognizant command. Pre-printed format paper and designated blocks of drawing numbers may be requested from the cognizant command.

5.25.6 Completeness of drawings. Level 3 drawings should be developed using the engineering sketches and specifications described in 5.24. As many subassembly drawings as possible should be prepared so that the top assembly drawing will be easier to read and build. A drawing tree for each assembly should be prepared prior to drafting to facilitate completeness and accuracy of drawings.

5.25.7 Computer-generated drawings. The preparation of detail and assembly drawings using Computer-Aided Design/Drafting (CADD) equipment versus traditional drafting methods may facilitate rapid and accurate input/output, updates/revisions, and storage/transmission of pertinent technical data. However, unlike drawings produced by conventional methods where lines can be blended and approximations made, computer-generated

drawings require more accurate inputs. For example, inaccuracies will become visible on plotted drawings if tangent arcs, circles, etc., are not defined to 3-

or-more decimal places.

5.25.8. Library files. The use of library files which include standard symbols; common parts such as bolts and washers; and standard notes, eliminates the task of re-drawing these items continuously. To aid in monitoring costs and compiling parts lists, input data may be extracted from drawing files.

5.25.9 Drawing references. The drawing references to specifications, military, federal, or commercial, should be backed up in a reference notebook or file. This list of references can be used to compile the data list when all drawings are complete.

5.25.10 Quality control review. A package submitted to Quality Control (QC) for review should be accompanied by a book or folder containing copies of all specifications used or referenced on the drawings. This could expedite the review by approximately 50%.

5.25.11. Candidate file inclusions. Copies of the drawings, associated lists, and technical data developed during this phase of the process should be included in the Candidate File (see 5.6).
