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 guide you to design a BOTTLE using image tracer function in Catia

V5. In this tutorial, we will learn how to add images, what are the parameters

required to consider and what can be done if we lost some icons. To create a

BOTTLE we have to work on Generative Shape design, Wireframe and surface

design and definitely Part design workbench.



Table of content:

Objective 1: Customize the setting of user interface

Objective 2: Creation of extrude surface

Objective 3: Adding material and image

Objective 4: Tracing the image using spline

Objective 5: Use of revolve command

Objective 6: Creation of arc

Objective 7: Creation of grip on the surface of bottle

Objective 8: Creation of revolve surface of bottle

Objective 9: Now creation of bottleneck

Objective 10: Use of revolve command to give surface

Objective 11: Monitoring revolved dimension

Objective 12: Creation of thick surface



Objective 1: Customize the setting of user interface

Open the attachment. Copy any image of that bottle and past on your

desktop and name it as Plastic Bottle.

Now open your catia user interface.

Go to the upper left corner and open start>Shape>Generative Shape Design.

Uncheck “enable hybrid design” and hit ok.

Go to the insert option in the top of the navigation bar and insert

“geometrical set”

Rename it as “setting 1” and hit ok.

Specification Tree



Objective 2: Creation of extrude surface

Select y-z plane from specification tree and click sketch icon.

Select Profile or line to create line with 50 mm height as shown in the

picture and exit.

Click on extrude icon set limits with Limit1=30mm & Limit2=30mm and hit

ok.



Objective 3: Adding material and image

Click on add material icon which is on you bottom navigation bar.

Go to other option and select material type as “Plastic”, click on the

extrude1 from specification tree then “apply material”, and close.

Change your view to “shading with material”

Double click on the plastic from the specification tree and chose rendering

option.

Type = image

Mapping = cubical mapping

Material size= 50mm

Browse image= Select “Plastic Bottle” from DESKTOP, and hit ok.

See the images mentioned below and follow the instruction carefully.



Browse



Objective 4: Tracing the image using spline

Select y-z plane and hit on sketch.

Select the axis icon and create an axis as centerline. Follow picture.

Select the spline and trace the image as shown in the picture.

You can customize the spline by simple click and drag.



OBJECTIVE 5: Use of revolve command

Select the sketch that you drew and hit on revolve icon

If you do not get the revolve icon then go to the Insert option on the upper

navigation bar

INSERT > SURACES > REVOLVE.

Set limit one as 180 and limit two as 0 and select revolution axis as the

sketch 1.

Then hit ok.

Now check whether the image you drew is identical with the picture mentioned

below. If yes then proceed to objective 6 otherwise make that image identical.



Objective 6: Creation of arc

Select the plane icon and assign

Plane type = offset from the plane

Reference = x-y plane

Offset = 20

Select plane1 and hit sketch icon.

Go to the circle option and hit on arc.

Create an arc similar with the image and exit



Objective 7: Creation of grip on the surface of bottle

Select y-z axis and hit on sketcher

Now opposite the direction of plane by normal view icon

Select spline again and draw the structure as shown below

Now see the picture carefully

Hit on rotate icon and make it little bit isometric, so that you can see the arc

as well as spline points.

Hold Ctrl+endpoint of arc+point in spline that is near to the arc and select

constraint definition and make it “coincident constrain



Objective 8: Creation of revolve surface of bottle



navigation bar


Set limit one as 180 and limit two as 0 and select revolution axis as the

sketch 1.

Then ok.

Now check whether the image you drew is identical with the picture mentioned

below. If yes then proceed to objective 9 otherwise make that image identical.



Objective 9: Now creation of bottleneck

Select y-z axis and hit on sketcher

Now opposite the direction of plane by normal view icon

Select spline again and draw the structure as shown below

Now see the picture carefully

Hit on rotate icon and make it little bit isometric, so that you can see the arc

as well as spline points.

Hold Ctrl+endpoint of arc+point in spline that is near to the arc and select

constraint definition and make it “coincident constraint”



Objective 10: Use of revolve command to give surface



navigation bar


Set limit one as 360 and limit two as 0 and select revolution axis as z-axis.

Then ok.

Now select rotate icon and check whether you get what you desire.



Objective 11: Monitoring revolved dimension

Double click on Revolve 1 and assign

Limit 1=360

Limit2=0 and hit ok.

Double click on Revolve 2 and assign

Limit1= 360

Limit2=0 and hit ok.



Objective 12: Creation of thick surface

Change your workbench START > MECHANICAL DESIGN > PART

DESIGN

Go to insert option

Insert > Surface-Based-Feature> Thick Surface.

A window pop out showing this is not a body hit ok.

If not then select the surface and drag the direction of arrow outside as

shown in the figure and assign Thickness= 0.3mm

Hit okk.

Similarly hit on other surface to obtain same result.



Now as you see the whole bottle is created and you can change the color by right

click on the specification tree and select properties.

Go to graphics option and change color as required.

You can also monitor the transparency from there and hit ok.
