| Drawing Guidance:
The following are tips on
getting a decent grade on your drawings for your design assignments.
-
The premise here is to make
your drawings as neat and as readable as possible eliminating errors and
ambiguity.
-
Remember, in the real world,
mistakes and ambiguity cost time and money.
-
In this class these mistakes
will impact your grade.
-
Always present your best work,
fix your own mistakes!
-
Double check your work before
giving it to others.
-
Check it on screen first
-
If any errors are found correct
them before printing
-
Check the printed copy second
-
If any errors are found make
the corrections then reprint.
-
If I find these mistakes and
mark up your work it will affect your grade.
Generalized Grading Criteria:
The list below may be modified
as the quarter progresses:
Appearance:
-
Center your drawing views in
the drawing area so that it fills the page without over crowding or leaving
excess space.
-
Try to provide equal spacing
between your drawing views and the top and bottom of the page as well as
from the left and right
-
This includes drawn objects
as well as notes and dimensions.
-
The spacing between the drawing
views and the border of the drawing should be about half of the spacing
between each of the drawings views in the field of the drawing.
-
Dimension your drawing views
according to conventional standards
-
Move dimensions around to avoid
"crowding"
-
Include the word "TYPICAL" following
dimensions that can apply to similar items in the same view such as a series
of holes, fillets or row and column offsets.
-
The isometric view should have
no dimensions in it.
-
Properly fill in your title
block, with CAPITALS only.
-
Provide an appropriate sheet
scale (a scale that applies to every view in your drawing):
-
Use standard scales such as
-
Metric: 1:1, 1:2, 1:5, 1:10
and similar multiples.
-
SAE: 1:1, 1:2 (6" = 1'-0"),
1:4 (3" = 1'-0"), 1:6 (2" = 1'-0"), 1:8 (1-1/2" = 1'-0"), 1:12 (1" = 1'-0"),
1:16 (3/4" = 1'-0") and similar multiples of 2,4 and 8.
-
Automatic scales added such
as 1:3, 1:7. 1.5:1 and other non traditional scales need to be modified
to standard scales.
-
Label each view with its own
scale if it is different from the sheet scale.
-
The isometric view should have
no scale label on it.
-
Provide a proper View Title,
in CAPITALS with UNDERLINED TEXT.
-
Position the View Title centered
under the drawing view.
-
The View Title should have the
following information answered in the following order top to bottom, what
is it? what view is it? what scale is it (if different from the sheet scale)?
and any note references that apply to that view.
-
Label each view with its own
scale if it is different from the sheet scale.
Avoid duplicate information,
this leads to ambiguity.
