Fundamentals of Drawing Engineering Design with SOLIDWORKS® 2016
The ASME Y14.5 2009 standard defines an engineering drawing standard. Review the
twelve changes made to the drawing to meet the standard.
No. Preferred Application of
the Dimensions:
1 Extension lines do not cross
unless situation is
unavoidable. Stagger
dimension text.
2 Largest dimension placed
farthest from profile.
Dimensions are evenly
spaced and grouped.
3 Arrowheads do not overlap.
4 Break extension lines that
cross close to arrowhead.
5 Flip arrows to the inside.
6 Move dimensions to the view
that displays the outline of
the feature. Ensure that all
dimensions are accounted
for.
7 Move text off of reference
geometry (centerline).
8 Drag dimensions into their
correct view boundary.
Create reference dimensions
if required. Slant extension
lines to clearly illustrate
feature.
9 Locate dimensions outside
off section lines.
10 Create a visible gap between
extension lines and profile
lines.
11 Arrows do not overlap the
text.
12 Whole numbers displayed
with no zero and no decimal
point (millimeter).Apply these dimension practices to the GUIDE drawing. Manufacturing utilizes detailed
drawings. A mistake on a drawing can cost your company a substantial loss in revenue.
The mistake could result in a customer liability lawsuit.
As the designer, dimension and annotate your parts clearly to avoid common problems
and mistakes.
Dimensions are displayed
in MILLIMETERS.
