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
from the drawing views and the border of the drawing should be about the
same as the between each of the drawings views both horizontally and vertically.
-
Dimension
your drawing views according to conventional standards
-
Move dimensions
around to avoid "crowding"
-
Dimensions
referencing the same feature such as a linear pattern, should be grouped
together.
-
Include
the word "TYPICAL" following dimensions that apply to similar items in
the same view such as similar sized holes, fillets, chamfers 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 by SolidWorks may include 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 or redundant information, this leads to ambiguity.
Redos:
All
work handed in for regrading must be stapled in front of the markup in
order for it to be considered for re-evaluation. |
