The following is how your
Title Block should look for the drawings due this week. Make any
additions and corrections necessary as shown below. Make sure you
make these corrections to your template files.
To change the units go to
"sheet format" right click on the text block, choose "Properties" and make
your text changes. Your "Name" (company name), "Initials" (drawn by), and
"Date" (drawn date (use a current date)) are set by selecting the "Properties"
option from the "File" pull down menu, choosing the "Custom" tab and selecting
and filling out the appropriate entry. The "Part Description" is
imported from your part or assembly being inserted into your drawing.
The sheet scale is set when you import a part or assembly and will change
when this is modified on the sheet. The drawing file name is what
you name the drawing file. All the text in your drawing should be
CAPITALS excepting the drawing file name.

Details on the design portion
of Examination No. 2 follow below.
These items can be accomplished
before and used for the exam.
Create the following, building
on your design from Examination No. 1
You will create three additional
components the
Barrow, Back Leg and the
Handle.
The Barrow will be a Loft Feature
with sketches drawn on two planes with sketch fillets. The top sketch
will be on the Top Plane with the bottom sketch on a plane 8 inches below
the Top Plane at the back and inverted at a 8 degree angle. After
the loft there will be a shell feature selecting the top face at 0.20"
thick. Add texture using Brushed Metal 4. Use a texture scale
at the bottom.
The
Back Leg will be a sweep feature as shown. The bolt holes will be
10" apart. Color will
be dark gray.
The handle will be your
own design. Standard credit for a no frills design. Extra credit
for finger grooves, ribs and other features. Material is rubber.
Extra credit will be offered
on extra details added to any feature as long as it adds to either the
form or function of the overall design. Examples include, but are
not limited to, treads on the tire, axle caps with flourishes (think, Ben
Hur and the chariot race scene), fenders, head lights, a brace connecting
the Back Legs, a pour spout on the front of the Barrow, streamers and hand
guards on the handle.
Modifications to the Examination
No. 1 parts include a new hole 10 inches behind the last hole in the Side
Mount to allow for the attachment of the Back Leg.
The Wheel Mount will now
be two different parts, Wheel Mount Left and Wheel Mount Right. Prior
to the exam, delete the holes in the Wheel Mount before making a copy and
renaming them. Both of these will be modified "in context" with the
assembly during the exam.
We will create a new assembly
and name it "Wheel Barrow". Make certain that all of your parts from
Examination No. 1 have been corrected, see your markups from the last exam.
Insert the axle (built with the profile on the right plane) "fixed" to
the origin in the new assembly. Next, add the Wheel Assembly as a
sub-assembly. With the center hole, provide a concentric relation
to the axle and with the right plane of the sub-assembly a coincident relation
with the right plane of the assembly. Add the Front Connector and the Side
Mounts without any relations with the Axle and the Wheel Assembly sub-assembly
yet (we will finish this during the exam). Mate the right plane of
the Front Connector to the right plane of the assembly. Mate
the Side Mounts to the Front Connector like we did for Examination No.
1. AThe bears in the back ground seem rather content. I don’t
understand the behavior, but If bears are like dogs, smelling the rear
end of your own kind is a pursuit my dogs certainly enjoy.
the Wheel Mounts to the Side Connectors with the left one on on the left
side when facing the front while holding the handles.
Details on the drawing portion
of this design will be available during the exam.

Final
Project Presentation Procedures:
In the
CAD lab, on the day and at the time allotted for the final:
Please
copy a folder, with your name in the title, of your project onto the instructor's
computer on my "desktop" into a folder named 080604-Final Project.
Come early if you can, however, there is a class final preceding ours and
we must be respectful of their time. Please leave your folder on
the desktop when you are done with the presentation so that I can grade
the parts and assembly portion of your project.
Our presentations
may run a little past the time allotted. Please prepare for that
and let me know if you have other time conflicts with this.
I will
have a presentation schedule posted on the website Tuesday evening.
The grade
sheet has been updated along with a tab named "Final" containing a grading
template for the presentation portion of your Final Project.
