Drawing a Gasket
Figure 5.77 shows a gasket that is symmetrical around its vertical and horizontal
axes. This symmetry will allow you to use the
MIRROR
command to create much
of the drawing.
The diagrams in Figure 5.78 summarize the steps.
To draw the gasket, set Linear Units to Engineering with a precision of
0
′
-0.00
″
. Set Angular Units to Decimal with a precision of 0.00. Now, follow
these steps:
1.
Use the
LINE
command to draw a rectangle 4
″
wide and 3
″
high.
2.
Offset the upper horizontal line and the left vertical line 1
″
to the
inside of the rectangle.
3.
Use
FILLET
with a radius set to 1
″
on the upper-left corner of the
original rectangle.
4.
Draw the circle with the 0.25
″
radius, using the intersection of the
two offset lines as the center.
5.
Erase the offset lines.
6.
Offset the right vertical line 2
″
to the left and the bottom horizontal
line 1.5
″
up.
7.
Use
FILLET
with a radius of 0.50
″
on the intersection of these two
lines, retaining the right and lower segments.
