Pro/ENGINEER 2001
Dr. Herli Surjanhata
Create a cylinder with dimensions shown below:



Note that the sketching plane is TOP datum plane, and use RIGHT datum plane as
right reference for orientation of sketching plane. This is one-side protrusion using a
circle as a section.



2
Create one-side protrusion representing hex bolt head as shown below.



Use the top surface of
the cylinder (bolt
body) as the
sketching plane.

Draw a hexagon as
the section, and the
distance across flats
is 0.375”.

Extrusion depth is
0.1667”.






3
Create a chamfer at the top of hex head using 360° revolved protrusion cut. Use
FRONT datum plane as a sketching plane, and draw the following section to be
revolved.






MODIFYING DIMENSION SYMBOLS

From PART menu, select

Modify - pick bolt body, hex head, and chamfer from the Model Tree.
