submitted, if labeled. Dimensions are required.
MD-2: Mechanical
Design and Drawing; 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 and N

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 P 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 Design and Drawing Presentation: "Solid
Modeling / Animation / 3D
Printed Projects"; - Groups
eligible to participate A, 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 multiview working drawings 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 multiview working drawings 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. All work submitted
must be original.
