 What is Creo Parametric?
Creo Parametric is the essential tool for 3D modelling.It is the state of the art software which
promotes best practices
in design and maintain your industry standards.It answer your present design challenges with
Creo Parametric which
is fully flashed powerful yet flexible 3D CAD availabilities.It can be used to accommodate
multi CAD data, electro
mechanical design and make alterations later in design process.

• The newly mirrored feature ensures symmetry, likely for mechanical balance or uniform
attachment points.
3. Next Steps:
• Additional refinements, such as fillets, chamfers, or further cutouts, might be applied to
enhance the design.
• The model could be prepared for assembly integration or finite element analysis (FEA).
EXPERIMENT 4
Aim: To model the given object using the Revolve feature as per the dimensions given
Description of Revolve Feature:
● Command Manager: Features > Revolved Boss/Base
● Menu: Insert > Boss/Base > Revolve
● Toolbar: Features > Revolved Boss/Base
Using this tool, the sketch is revolved about the revolution axis. The revolution axis could be
an axis, an
entity of the sketch, or an edge of another feature. Note that whether you use a centerline or
an edge to
revolve the sketch, the sketch should be drawn on one side of the centerline or the edge.
After drawing the sketch, as you choose this tool, you will notice that the sketching
environment is
closed and the part modeling environment is invoked. Similar to Extrude, including the
sketches, the
resulting feature can be a solid feature or a thin feature depending on the sketch and the
options selected.
● If the sketch is closed, it can be converted into a solid or thin feature.
● If the sketch is open, it can be converted only into a thin feature.
Procedure (for Revolve):
1. Select Front Plane
2. Use Sketch option to draw the profile (don’t worry about dimensions initially).
3. After drawing the sketch, draw a centerline over the Y-axis.
When the sketch is complete, click the green tick (✓). The view automatically switches to
3D, and the
Revolve Property Manager opens.
● Click the Revolve button● Select the centerline as the axis of revolution
After Revolving:
● The 2D sketch will be revolved 360°
● A 3D feature is created
Result: Thus the given model is drawn using revolve feature

EXPERIMENT 6
Aim: To model the given object using the Revolve feature as per the dimensions given.
Description of Revolve Feature:
Command Manager: Features > Revolved Boss/Base | Insert > Boss/Base > Revolve
Toolbar: Features > Revolved Boss/Base
Using this tool, the sketch is revolved about the revolution axis. The revolution axis could be
an
axis, an entity of the sketch, or an edge of another feature to create the revolved feature. Note
that whether you use a centerline or an edge to revolve the sketch, the sketch should be drawn
on
one side of the centerline or the edge.
After drawing the sketch, as you choose this tool, you will notice that the sketching
environment
is closed and the part modeling environment is invoked. Similar to extruding the sketches, the
resulting feature can be a solid feature or a thin feature, depending on the sketch and the
options
selected to be revolved. If the sketch is closed, it can be converted into a solid feature or a
thin
feature. However, if the sketch is open, it can be converted only into a thin feature.
Now a window with planes will open. Now we have to draw a sketch to revolve. Here we
start
Select Front plane and using sketch option draw a sketch as in the fig. After drawing sketch
draw
a center line over Y-axis.
You will notice that the view is automatically changed to a 3D view, and the Revolve
Property
Manager is displayed. After sketching, click the Done button. In the new window click the
Revolve button.
Some command line will open and the program will ask you to select a reference. Here the
reference is the line about which our sketch has to move around. In this practice we will use
that
center line that we have drawn in sketching. After selecting that line as reference, the
program
will show you a demo of your sketch as a revolved part. If you want to see how your part will
look you may click the “glasses” button; if your part is well according to you then click Done
Revolving.
Procedure:
1. Select a sketch plane (Front, Top or Side).
