Mechanical Drafting Division
Entries in the classification within this division which include more than one sheet must be bound together along the upper, middle, and lower left-hand edge of the completed set. Small drawings should be on top with larger drawings on the bottom. Drawings must be kept flat. "No title blocks containing personal identification data will be allowed. A single line border or no border is recommended, "No" school graphics or names maybe included on the drawings or cover sheets" violation of this guideline will result in a 10 pt. penalty for the violation . If tracing media is used and the original drawing is not directly on tracing media, the original must be the student's own work. Indication must be made whether or not the work submitted is original.

3D printed projects should be entered in MD-4: 3D Solid Modeling for Presentation . These entries should be of the students own creation, and include drawings with dimensions.

Basic Mechanical (Board Drawing); This classification is for students with less than one credit in mechanical drafting. One or more instrument drawings (no sketches) drawn with pencil or ink on drawing or tracing media, not larger than 24" x 36", are eligible. This classification may include a drawings of a machine part and pictorial drawings; "the drawing should include and orthographic projection/multiview drawing {3 views}with dimensions and an isometric drawing that represents the depicting the orthographic projection". Workbook sheets may be submitted, if labeled. Dimensions are required. Student may download the problem for the year and do it if they wish.  Groups eligible to participate A, B, and E

MD-2: Mechanical Computer Aided Drafting (CAD) "Production Drawings" Scoring Guide for MD-2
This classification is for students enrolled in a mechanical drafting (CAD) course with an emphasis in Orthographic/Multiview Working Drawing. The entry shall consist of a complete set of detailed and assembly orthographic drawings done with a Computer and the aided of a Drafting and Design Program (software). Any drawings may not be printed on media larger than 24" x 36" are eligible. This classification is for orthographic working drawings. Isometric or pictorial drawings are not required for MD-2. But if students wish to include an isometric or pictorial representation of the entry as their cover page, it will be allowed but no more than one pictorial will be allowed.

Drawing requirements for Groups A, B, and E
Drawings of machines, accessories, jigs or fixtures, or any CAD drafting project of this nature may be submitted. Detailed Orthographic / Multiview drawings must include dimension. The entry must include an orthographic / multiview drawing with dimensions, a single pictorial drawing and a selection of not more than three detail drawings. This classification may include drawings of machine parts or assembly drawings. Irregular shaped objects that have either practical or theoretical applications are eligible. The developmental drawings must be properly detailed and include dimension. The student may not have more than 5 sheet in this entry.

Drawing requirements for Groups C and D
Advanced Mechanical (CAD); This classification is for students who have completed more than one full year or two semesters in a mechanical drafting course. The entry shall consist of a complete set of detailed  orthographic assembly drawings including dimensions generated with the use/aid of a computer on suitable plotter media not larger than 24" x 36" are eligible. Drawings of machines, accessories, jigs or fixtures, or any advanced drafting project of this nature may be submitted. Detail drawings must include dimension. A single entry must include an orthographic assembly drawing and a selection of not more than five detail sheets. If six or more sheets are involved in the project, the assembly drawing and the best five detail sheets must be selected and submitted. A selection may not have more than five developments drawings. Irregular shaped objects that have either practical or theoretical applications are eligible. The developments drawings must be properly detailed and include dimension..The student may not have more than 6 sheet in this entry.

MD-3: Mechanical Drawing Presentation: "Solid Modeling / Animation / 3D Printed Projects"; - Groups eligible to participate N and P.   Scoring Guide for MD-3
The entry shall consist of a computer generated drawing of machines, accessories, jigs or fixtures, or any advanced drafting project.
Option I:
The entry includes the animation in the rendered mode. The title of the entry must be presented within the animation. The animation drawing must be student generated, while the background and/or text fonts can be part of the computer program. The animation drawing must be generated totally by the student. No sample components or sample animation's are permitted with the entry. The animation must be on display and running for the judges to view the entry. This entry must include a selection of no more than five orthographic drawings of the parts used in the model including dimension. If five sheets are involved in the project, An assembly drawing and the best four detail sheets must be selected and submitted. The work submitted must be original. These drawings must be printed on media not be greater than 24" x 36".
Option II:
This category uses the technique for representing solid modeling objects or 3d printed through computer processing. These entries are 3d computer models in this classification are for the presentation of a mechanical part or machine shown by a mechanical draftsman to his client. Modeling methods include surface models, (used extensively in automotive and consumer product design) and wire frame models. Solid models are for CAD, engineering graphics, rapid prototyping, or 3d printed product visualization. Solid modeling creates a virtual 3D representation of components for machine design and analysis.

Entries must:  include an orthographic / multiview working drawing with dimensions, a selection of no more than four detail drawings of the parts used in the model. If five sheets are involved in the project, the multiview working drawing with dimensions, plus assembly drawing and the best three detail sheets must be selected and submitted.
or

Selection should include an orthographic / multiview working drawing with dimensions, and no more than four pictorial exploded or other types of pictorial assembly drawing of the 3D model. Details of three of the principal parts including dimensions must accompany the solid model drawing on suitable media or displayed on a computer. The printed media must not be greater than 24" x 36". Indication must be made whether or not the work submitted is original.
Work submitted must be original.

Group (A) - Middle School: 6th, 7th or 8th grade.
Group (N) - Novice: a person or group who is new to the circumstances, work, etc. in which he or she are placed; beginner; tyro: a novice in the entry area. This entry area is for the 1st year the student has entered in this project area.
