Lesson 1 S ketcher W ork B ench

Introduction To The Sketcher Work Bench

This lesson will take you through each step in creating a simple sketch and ending with a

part that will be referred to as the “ L Shaped Extrusion ”. Later in this lesson you will

be asked to save this part (file) as the “ L Shaped Extrusion.CATPart ”. The completed

“ L Shaped Extrusion ” is illustrated in Figure 1.2. In some cases, optional processes will

be explained. Referenced illustrations will be used to help explain certain processes and

to compare results. It is important that you complete and understand every step in this

lesson; otherwise, you will have difficulties in future lessons where much of the basic

instruction will not be covered (it will be assumed that you know it). The concepts taught

in these steps will give you the tools to navigate through the basics of the Sketcher

Work Bench . Following the step-by-step instructions, there are twenty questions to help

you review the major concepts covered in this lesson. There are practice exercises at the

end of this lesson. The practice exercises will help you strengthen and test your

newfound CATIA V5 knowledge. This lesson covers the most commonly used tools in

the Sketcher Work Bench . The less common and/or advanced tools will be covered in

later lessons and/or in the Advanced Workbook. It is not the intent of this book to be a

comprehensive reference manual, but provide basic instructions for the most common

tools and functions in CATIA V5. CATIA V5 in the Windows NT environment allows

multiple methods of accomplishing the same task. You are encouraged to explore all of

the different options.

Sketcher Work Bench Tool Bars

There are three standard tool bars found in

the Sketcher Work Bench . The three

tool bars are shown below. The

individual tools found in each of the three

tool bars are labeled to the right of the

tool icon.

Some tools have an arrow located at the

bottom right of the tool icon. The arrow

is an indication that there is more than

one variation of that particular type of

tool. The tools that have more than one

option are listed to the right of the default

tool. To display the other tool options

you must select and hold the left mouse

button on the arrow as shown in Figure

1.1. This will bring up the optional tools

window. Move your mouse to the desired tool and release the mouse button. The desired

new default tool is to double click on it.

NOTE: The three tool bars are, by default, located on the right side of the screen.

The three tool bars contain too many tools to show all of them in one

Lesson. To view and have access to all of the tools, you can select the

shaded tab located at the top of each tool bar and drag it anywhere on the

screen. This is important, because when you get to Step 12, by the

default setup, you will not be able to visually locate the Operation tool

bar. You will have to select and drag the Operation tool bar from the

right bottom side of the screen to the location you select .

Steps To Creating A Simple Part Using The Sketcher Work Bench

You are now going to use the tools just introduced to you to create an “ L Shaped

Extrusion ”. The part is referred to as an “ L Shaped Extrusion” because its profile or

shape is similar to an upper case letter L. When you complete all of the steps in this

lesson, the result should look similar to the part shown in Figure 1.2.

1 Start CATIA V5

From the NT Desktop , double click on the CATIA V5R5 icon. Be patient, it may

take a few moments to bring up the CATIA V5 start logo and the actual CATIA V5

working window. Figure 1.3 shows what the screen should look like.

If you are not able to finish all of the steps in this lesson in one session, you can jump

to Step 23, which covers saving and exiting CATIA V5. This will allow you to save

your work for your next session.

2 Select The Sketcher Work Bench.

Every time you start CATIA V5, the CATIA V5 screen will appear as it does in

Figure 1.3. The “ Welcome to CATIA V5 ” pop-up window will prompt you to select

a work bench. The default work bench is Product Structure . For this lesson, you

will need to select the Sketcher Work Bench . Notice, as you select the Sketcher

Work Bench that the tool bars on the right hand of your screen change and the

“ Welcome to CATIA V5 ” pop-up window disappears. If your CATIAV5 screen

Creating A Simple Part

and/or your Sketcher Work Bench screens are not maximized, maximize them using

the Windows function at the top right of the screen.

For future reference, there are two methods to select a work bench in CATIA V5. As

you start CATIA V5, you are prompted by the default method. Using the “ Welcome

to CATIA V5 ” pop-up window is one way. Once you have selected a work bench

and the “ Welcome to CATIA V5 ” window has disappeared, you can bring it back up

by selecting the Work Bench icon in the top right of your screen, reference

Figure 1.4. The term work bench is used generically, because the Work Bench icon

showing will be the current active work bench. Selecting that work bench will bring

up the “ Welcome to CATIA V5 ” pop-up window.

The other method of selecting another work bench, is by selecting the Start icon in

the top left side of the screen, reference Figure 1.4. This will bring up a pull down

menu that includes all of the work benches. Double click on the work bench you

want to use, in this case the Sketcher Work Bench .

Figure 1.4 shows what the menus look like on the screen for both methods described

above. It is not possible to use both methods at the same time as shown in Figure 1.4;

you can only use one method at a time.
