1. Go to my website
2. Click on (CO) MECH 289 Design Graphics.
3. CO MECH 289 Schedule 2010. You will find all assignment beginnings and due
dates there as well as the marking scheme at the end.
4. To see what kind of questions you’ll face on 10-03-23 (Tues.) and 10-03-25
(Thurs.) in the mid-term tests CO … Mid-Term Tests ’08, ’07, ’06.
5. Tuesday lectures, by Paul Zsombor-Murray (, will draw on
some topics detailed in CO MECH 289 Fundamentals of Geometric Construction*
and CO MECH 289 Elementary Descriptive Geometry and Equivalent Linear
Algebra*. These apply to two geometric construction assignments GC1 and GC2,
as noted on MECH 289 Schedule 2010, as well as to mid-term questions.
6. GC1 begins today. It is simple-to-draw but important. It is a not-so-simple method
to analyze planar, panel point loaded pin jointed structures consisting of axial
force members (T, C or 0). It is available at CO MECH 289 Geometric
Construction Problem 1:- Maxwell’s Diagram.
7. Thursday lectures, by Syedhossein Hajzargarbashi (Amir), are on AutoCAD. They will apply to assignments CAD1
through CAD6 as noted on MECH 289 Schedule 2010. CAD 1 will be a simple
drawing based on GC1, p.2, the link-and-pin triangular panel. CAD 2 and CAD 3
are architectural floor plan layouts while CAD 4 through CAD 6 will address
sections of the final project task, to graphically document the structure shown in
the photos MECH 289 Project Photos 10-01-05*
8. is your TA. He’ll meet ½ the class in FDA1 on
Tuesdays, right after the lecture. Go there only if your name is KOWALCZYK or
precedes it in the alphabet. He’ll, similarly, meet the other ½ on Thursdays. Go
there only if your name is KWAN or succeeds it in the alphabet. This is due to
limited computer resource lab space. You must work independently with
AutoCAD to complete your GCi and CADj assignments and you may use any
facilities available to you, e.g., EMF in MDHR basement.
9. The FINAL PROJECT will consist of a collection of drawings:- a) Cleaned up
versions of CAD 1 … 6, b) Other details and c) As much of the assembly that
you’ve managed to date and put together.
10. Grades will be assigned based on quality, quantity, completeness, improvements
to fastening, modularization, transportability, assembly technique and application
of drawing standards and conventions to make your “working drawings” simpler,
clearer, neater and more complete. E.g., bolt pattern abbreviation and use of weld
symbols; avoid drawing bolts and weld beads even if you think they’re cool.
Riggers and welders should know their trade and how to read drawings as it
applies to their métier. The various “descriptors” will be weighed and applied
somewhat subjectively. E.g., someone who completes only 60% of the structure
but does a thorough & neat job on that part can get an “A” while someone who
completes everything while exhibiting poor overall quality and errors in
dimensioning and/or drawing convention will be penalized.
