Introduction

Designing is all about innovation which breaks all the barriers of imagination.

Though designing is the root of imagination but it is like a branch which spread

and spread wider. The more you go nearer the more it gets robust. Designing is

something which you cannot count, which you cannot weight but all we can do is

feel the richness of design.

Let me give you an example:

We go home, we sit on a chair and we use the comforts. Did ever we thought that

why it is so comfortable? Yes, we do but the only difference is we feel the design

in terms of comfortness and looks.

Now we understand that designing is very much important to our day-to-day life

and its something beyond measure.



This book will help you to design a BOLT in 3-D. Get your basic clear with me

and discover yourself. The following guideline will direct you to create a BOLT using CATIA.

Open Catia, then go to the upper left corner of the navigation bar

Start>Mechanical Design>Part Design

Now click on the YZ-axis from the specification tree and hit on “Sketcher icon”

Create a hexagonal structure as shown in the figure

Give constraint definition 60 mm and exit sketcher.



Use pad definition and assign Type= Dimension and Length= 30

Now hit on x-y plane and create a centerline and exit

Again, hit on x-y plane and create a triangular shape from “Profile”

as shown in the figure and exit.



Now change the work bench, go to the upper left corner of the navigation bar

Start>Mechanical Design> Wireframe & Surface design

Go to the “Insert” option in the navigation bar

Insert>Surfaces> Revolve

Another window pop out, Assign Profile=sketch 3(Triangle) &

Revolution axis=sketch 2(Line)

Limit 1=360 and Limit 2= 0 as shown in the figure.



Now again change the workbench


Go to the “Insert” option on the upper navigation bar

Insert>Surface –Based features>Split

Click on the yellow or revolve section and hit ok.

Now right click on the revolve area and use “Hide” option.

If you got the image similar to the figure shown in the picture then continue next step.

Otherwise, double hit on the split definition from the specification tree and reverse the direction of

the arrow shown in the figure.



Now select plane face and hit on the sketcher.

Create a circle with Diameter=45mm and exit the sketcher.

Use pad definition and assign Type= Dimension and Length= 140mm

Now hit on x-y plane, create a point, and assign the dimension as shown in the figure and exit

The point should be co-incident the edge. If not then do it.



Now change the work bench, go to the upper left corner of the navigation bar

Start>Mechanical Design> Wireframe & Surface design

Go to the “Insert” option again

Insert>Wireframe> Helix

Click on that point that we have created and in the axis hit on the sketch of straight line

Give Pitch=8mm

Height=100, hit reverse direction if necessary and hit ok.

See the picture carefully



Now we have to create a plane through which we can create a profile for slot definition.

Hit on plane icon, Plane type= Normal to curve

Curve= Helix

Point=End point of helix.

Hit on the plane, which we have created and go to the sketcher.

Create a circle with diameter 7.2mm and exit.



Now again change the workbench


Go to the slot definition Icon a small window pop out

Profile = Circle (7.2)

Center curve= Helix

Check list on the thick profile and hit ok.



Now go to the insert option

Insert>Dress up Features> Chamfer

Click on the edge of the bolt and assign

Mode=Length1/angle

Length 1=5

Angle=45

Object to chamfer=Slot1/Edge1

Propagation=Tangency and hit ok.



GO TO THE SHADING ICON AND HIT ON “SHADIND WITH EDGES”
