ME 301 INITIALS ASSIGNMENT
Draw your initials in the top plane using minimum dimensions and maximum relations.
This should be a ‘powerful’ sketch that can be easily rescaled. Properly use the
origin and define your sketch without using "fix". Next, make your initials "cool and
3D" using feature tools like extrude, shell, fillet, chamfer, etc. Add personal touches
like shading, texture, color, etc.
Turn in the following pre-CAD plan:
design layout sketch/notes (2-D hand drawing with construction lines, basic shapes,
origin selection, basic dimensions, planned use of relations to create fully defined
sketches, simplifying assumptions, and general plan of attack)
Turn in the following process documentation:
design journal (including sketches with relations and dimensions, discussion of your
use of sketch tools, development of your extruded final product, annotated design
tree, completed part file properties summary and custom tabs, and at least three
lessons learned through the assignment). Capture and comment on your work at
intermediate stages of development. Note: completed part properties should include
Author in the Summary tab, and Quantity, PartNo, Material, and Description in the
Custom tab.
Turn in the following products:
fully-defined sketch of your initials before extrusion.
solid model showing details of your finished product in the display window. Use color
screenshots in your word doc for a more impactful presentation.
engineering drawing of your finished product (including shaded isometric view, non-
redundant orthographic views, part properties, necessary and non-redundant
dimensional annotations). Use the ME drawing template (3rd angle orientation and
data exchanged between the part and drawing using part property information).
Pre-CAD plan #1
(missing initial Pre-CAD plan grading sheet)
Not many constraints

sketch
Pre-CAD plan Revised
Sketching a blank block to work from
I started by sketching a square on the top plane with the bottom left corner at the origin.
I then extruded the base to a height of 2 inches.
Sketching the text
I created a new sketch on the front plane of the box and drew my initials “JDE” using the line
tool. I used a global variable and set all my text lines to be “0.4 in” apart and made sure they
were parallel using the parallel, vertical, and horizontal constraints.
I created a new sketch on the right side of the initial box and drew “ME301” using the line tool
as I did in the previous sketch. Because this sketch was more complex, I tried to use more
constrains and minimize the number of dimensions needed to fully define it.
Extruded cutting the text
First, I used the extruded cut tool to remove everything outside of the sketch body leaving only
my initials “JDE” behind.
I repeated this process with the sketch of the “ME301” text.
Creating the final profile
Using a reference plane (per assignment guidelines) 0.5 inches above the top surface of the part,
I sketched a final profile. The outside rectangle of the sketch was made colinear with the front
and back face. Coincident constraints were used to define to corners.
I played around with a few profile sketches and finally settled on one that eliminated any features
floating in the air but still showed all the desired text.
Setting Part Properties
I renamed my sketches and extrusions with a descriptive name, and set the material to be PET plastic
(which is commonly used in 3D printing).
I also updated the summary information and custom tab.
Final Product
When looking at this model from any direction other than the front or right side, it is difficult to
read the text. However, when facing the model from the correct angle, it is easy to read “JDE”
(front face) and “ME301” (right face).
Top View
Front View Right Side View
Isometric View
Making the drawing
I created a drawing with the front, top, right, and isometric view. I then used the smart dimension
tool to annotate the important dimensions of this model. I used the annotation “TYP” to indicate
that all letter thicknesses of 0.4 inches were typical.
Lessons Learned
1.) When using a single dimension that is repeated multiple times in a sketch, it is helpful to
create a global variable. This way, if it needs to be modified at a later date, it only has to
be changed in one location.
2.) Using constraints can help to reduce the number of dimensions needed to fully define a
complicated sketch.
3.) It is important to make sure all of your sketches are fully defined, but this can get difficult
when there are a lot of line segments.
