MEC 1011 - Design Communication I
Part Documentation and Sheet Metal
the end of our ‘Lab’ meeting in Week 4
First, make a new project file (.ipj) in V:/MEC/1011/Fall_05/Assignment6/TXA/Yourname
PART 1 – Use
Inventor to produce a working drawing of your paper weight
paper weight with Inventor (.ipt ).
Open a new drawing file (.idw). Set sheet size
to A (portrait or landscape). Use the ANSI standard border and title block.
Place the base view of your Paperweight in the
.idw, and then project the other necessary views and an isometric view. Include
hidden lines only where they add clarity.
Fully dimension and tolerance the drawing. Stock
sizes should be found on this list of preferred sizes (consider a
fractional dimension style for stock to indicate that no tolerance applies).
Demonstrate the use of flatness and orientation (parallel or
perpendicular) geometric tolerances. Use hole notes where appropriate. Remember
to tolerance all angles.
Hand in a print of the drawing at a 1:1 scale
(the drawing can have any standard and appropriate scale, but the printing
process should be set to 1:1).
PART 2 – Model a sheet metal enclosure
Conditions and Objectives:
Model all other dimensions at decimal sizes of 3
places or less (i.e .020 or 1.031 but not 2.3452383).
The base and top will have a “line to
line” fit, which means that the interior dimensions of one piece will be
exactly the same as the exterior dimensions of the second piece where the two
pieces mate together.
Use Contour Flange or Face and Flange to form
bottom and sides.
Use Punch Tool or Insert iFeature to emboss feet
Use Cut and Rectangular pattern to model the
Use Flange on both ends with holes at the minor
diameter of 6-32.
Use Fold to fold in sides to expose handle.
Avoid exposing sharp edge at limit of hem on the cover (Ex. with a 1” hem
on cover overhanging .25 you wouldn’t want to fold in more than .70).
Use Hem to hem as much of the cover as
practical. Hem generously where the edges of the cover are used as handles.
In the front use cut to form a Ø ¾” hole
for a button and a rectangular opening in the front for a keypad opening. This
opening must be 1 ¼” x 2 ½”.
Use iFeature or Punch Tool place a D-Sub
Connector-4 opening on the rear of the enclosure. Locate it in the exact center
of the back.
Line up Ø.150 thru holes to the #6-32 holes on
Create a flat pattern view of one of the parts
and place it in an .idw
