MEC 1011 - Design Communication I
Fall 2007 Final Project
Due at the end of your Final Class.
This project will incorporate all the skills we have practiced thus far.
Produce a complete set of working drawings
for the chosen design using SolidWorks. All files
will be saved in the Q: /MEC/1011/Fall_07/T4/Final/ folder. In your folder you
will have 2 new folders; one for templates and 1 for ToolBox
Parts. Be sure to direct your file locations to these folders. Your models
should include logical sub-assemblies. Use A-size portrait sheets
and ANSI A title blocks (or custom title block). (By
creating templates you will be able to prefill the
properties for both your drawings and models)
Turn in a paper package consisting of:
A title page including a rendering of your
machine in its environment and typical info such as Name, Date Section, etc
Your set of working drawings (printed 1:1 with
drawing scale of your choice).
Produce motion and assembly animation files (10M
max each). Animate sub-assemblies separately.
Produce a PowerPoint slide appropriate for the
36” plotter (17” x 17” sheet of paper). Your slide should
feature a rendering of your machine (2000 pixels wide with aspect ratio locked)
surrounded by images of your working drawings, See Example
Create a set of e-Files and appropriate READ-ME
Each working drawing and the set of drawings must be complete.
All Working Drawings: Include formal (consider
standard ANSI A) title block and border. Title blocks include scale, author,
checker and date, title.
Assembly Drawing(s): Include exploded and
assembled views (at least one of each - your choice of ortho,
section or iso and consider two sheets) necessary to
clearly show (consider detail views) what parts and how they go together. Also,
include balloons (on assembled and exploded views), a parts list and good
trails on any explosion. The parts list should at least include Item
number, Quantity, material, and a column to name custom parts and clearly
specify standard ones. The names of custom parts must match titles given on
Part Drawings: Include all views and dimensions
necessary to define the part geometry.
Drawing Set: Include an assembly drawing for
each assembly and sub-assembly and part drawings for each custom part.
Challenge: Model and dimension in metric units. (20 point
Avoid Contradictions: Never use the
decimal places of the style (appearance) of a
dimension (unfortunately Inventor calls this the ‘precision’ of the
number) to round off a quantity. For example, if the length of a feature
is 1.625, you should not allow its dimension to state 1.6.
Dimension hole sizes
and list characteristics using hole notes (use quantity note to show # of
common holes - like 2X- edit hole note). This requires the also desirable use
of hole features to model holes.
Dimension a hole’s
location by referencing a centermark or centerline.
Place extension lines with visible
Give meaningful names to your all files.
Place dimensions off the views
If you’re stuck designing in English
units, think in simple decimal sizes when you design (like 1.6), and use
fractional sizes for stock and standard components only. When you use
fractional sizes (like 1.625), dimension them with a fractional style (like 1 5/8).
Avoid over dimensioning (saying the same thing

Holes are tapped by modifying a hole feature
(not by adding a thread feature).

Specify part finish (using notes or symbols).
Where a part is symmetrical, indicate symmetry
with a centerline and tolerance the symmetry with a note.
