Introduction.
Select New: and Part and then select OK This is yet another way of starting a new Part Select the yz reference plane and then Sketcher: or vice-versa Select Profile: and create line segments with endpoints inline with the vertical axis reselect to deactivate the Profile: command icon Note:To end the definition of a Profile which does not finish at its start point , Select Axis: and define a line joining the endpoints Press MB1 to deselect the line Double-click Constraint: and create the 3 distance dimensions from the axis Double-click each dimension value, and enter the required value as shown Vertical offsets 50mm and 35mm, and horizontal offset 50mm Note:The Axis line is not fixed it could be dragged away from the vertical axis 2.
To create a solid of revolution from the Sketch profile Select Exit: and Shaft: Note:If the Sketch did not contain an Axis type line, then it would be necessary to select an axis of revolution, for example the vertical V axis. Define shell thickness operation 4. Create gudgeon pin hole and 2mm chamfer 3.
Piston Part continued Select the bottom face for removal Enter an Inside thickness of 10mm 4. Although the circle has been created efficiently, the circle is unlikely to be moved from the origin in this example, and therefore would have been more appropriately created as a Circle: using the origin as its centre point.
Define the 35mm oblong profile 2. Create Pad and define an R25mm circle 1. The individual tools found in each of the three Select arrow 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 Optional tools tool. To display the other tool options you must select and hold the left mouse button on the arrow as shown in Figure 1. This will bring up the optional tools.
Move your mouse to the desired tool and release the mouse button. The desired tool icon now becomes the default tool, shown on the tool bar. All you have to do to select the new default tool is to double click on it.
Arrow indicates multiple tools are available. Click on the arrow and the other tool options will appear. Tools covered in this lesson: Corner, Chamfer, Trim and Break.
Symmetry and Project 3D Elements tools will be covered in Lesson 2. Profile, Rectangle, Circle, Line and Point. 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 at one time. To view and have access to all 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 4, 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. When you complete all the steps in this lesson the result should look similar to Figure 1.
Figure 1. If you are not able to finish all 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. The default work bench is Product Structure. For this lesson you will need to select the Sketcher Work Bench. The term work bench is used generically because the Work Bench icon showing will be the current active work bench.
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. 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.
It is not possible to use both methods at the same time as shown in Figure 1. Pull down menu Pop up window. This window can be customized. The Sketcher Work Bench should be included in the default window.
The next step is to create a 2 dimensional profile of the part. The Sketcher Work Bench is a two dimensional planar work area.
To use the Sketcher Work Bench you must specify which plane the profile is to be created on. Specifying the plane can be done several different ways. Notice as a particular plane is selected the equivalent plane in the Specification Tree is highlighted.
CATIA V5 Student edition
To do this just select the Plus symbol to the left of the Specification Tree or double click on the branch you want expanded. Select the plane in the Specification Tree and the coordinating plane in the center of the screen will also be highlighted. This option will be covered in more detail later in the book. XY plane YZ plane. The default grid will also appear.
This means that there are several methods available to complete almost every task. This brings up file tab options on the right side of the screen and file type options on the left Figure 1. From the options on the left select Part, the tabbed options on the right change accordingly. There are four main options under Sketcher; you only need to use two of them at this time, Grid and Sketch Plane. For this particular exercise check the Display option.
For this particular exercise check the Snap To option. The user can set the desired spacing. If the default measurement is in metric the spacing will be in mm. To change this default complete the following steps:.

This is in the same window as described in Step 5. The window on the screen should now look like Figure 1. For this exercise select inches. Notice the Primary Spacing option is now showing in inches. This option divides the Primary Spacing in divisions defined by you, reference Figure 1. To change the Primary Spacing and the Graduations just select the value in the window and type in the new value. When entering the values for the Primary Spacing it is not necessary to enter the measurement type.
The lowest value allowed for Graduations is 1 zero will not be accepted.
For this exercise enter 1 for the Primary Spacing and enter 10 for the. It is important to remember that the zoomed view on the screen will dictate how the Primary Spacing and Graduations are represented. If you are zoomed out, the Graduations and Primary Spacing could look very similar to each other, not distinguishable. If you find yourself in this situation use the Zoom tool on the tool bar at the bottom of the screen Figure 1.
Continue to zoom in until the Primary Spacing and Graduations are distinguishable. Primary Spacing. Graduation Zoom Zoom in out. The first tool you will use from the Profile tool bar is the Point by Clicking tool , covered in Step 7. The second tool is the Line tool , covered in Steps 8, 9 and The third tool is the Profile tool , covered in Step On the Tools tool bar at the bottom right of the screen make sure the Snap To Point is on highlighted , the Geometrical Constraints is on and the Dimensional Constraints is on Figure 1.
With this you are ready to create geometry!
Reference Figure 1. The starting point for your profile will be 1,1. You should be able to locate the 1,1 location using the Primary Spacing and Graduations. To visually verify the location and to Anchor your first two lines to the 1,1 location create a point at the 1,1 coordinate location.
To create a point complete the following steps:. This tool allows you to select and snap to a location on the screen. Another way of specifying the location of the point is to type the location in the Point Coordinates: The H: Hit the Point 1,1 Tab key to move the cursor over to the Vertical box.
Type in 1 for the Vertical Constraints coordinate. It will remain highlighted until you make another Figure 1.
There will be two green dimension lines locating the point from the 0,0 location. The dimension values should be one in the horizontal direction and one in the vertical direction.
The green dimension lines constrain the point to that coordinate location Figure 1. Notice New point a Point. Remember, you may have to expand the Specification Tree to see all the entities. This means the dotted lines represents. Complete the following steps to create line 1. This will bring up the Tools pop up window as shown in Figure 1. When you select the Line icon your mouse will be accompanied by a Target Selector. Using your mouse select Point. The Tools pop up window will also up date to prompt for the end point.
If you can use the grid to locate the correct location do so. Click on the grid line intersection 1,2. If you have any doubt where 1,2 is type in the values, using the Tools pop up window. Type in 1 for the H: Line 1 should look like the one labeled in Figure 1.
Connecting one entity to another is safer and easier when the Snap To Point icon is on. When the Snap To Point icon is off you must be careful when connecting one entity to another.
Both entities must share the same common point. For example, two connected lines, the end point for the first line must be the same exact starting point for the second line. The lack of a shared point will make the entities unlinked. The entities will not move together. Another problem with the broken link is that it creates an unclosed profile. Unclosed profiles will be covered later in this lesson. The symbol is shown in Figure 1.
This will link the two entities together. This is a helpful tool, especially when the Snap To Grid tool is off. The Tools pop up window gives you more options than the ones covered in Step 8. If you are typing in the information to create a line you have the option of giving Polar Coordinate information.
This lesson does not require you to use this option, it could be helpful in the future. Repeat the same process described in Line 1 Steps 8, except use 1,1 as the Start Point and 2,1 1,1 as the Ending Point. This will create the bottom Line 2 horizontal line as shown in Figure 1. Double clicking on the Line icon will allow you to create multiple lines without being required to repeatedly select the Line icon.
With the Line icon double clicked, create line 3, Start Point 2,1. The End Point for line 3 is 2,1. Double clicking on the Line icon still requires you to select a Start Point and an End Point every time, but you will not have select the Line icon for every line.
If you make a mistake when creating one of the lines you can use the Undo icon. The Undo icon is located at the bottom of the screen. The Undo tool allows you to undo multiple steps.
Another option to a mistake is deleting it. This can be done using the Cut icon also located at the bottom of the screen.
Highlight the entity to be deleted then select the Cut icon. The Profile.
The connected lines will continue to be created with every point selected until you double click. Double clicking the Ending Point will end the Profile command.
The lines created are separate entities, but the command that created them is recognized as one, so if you select the Undo command all the lines created in one Profile operation will be undone. Create lines 4, 5 and 6 by selecting the following coordinates in succession, select 2,1.
The finished profile should look like Figure 1.

This particular exercise does not require any features with radii but the Profile tool has the ability to create them. Instead of selecting an End Point and a Starting Point for line creation, select the point where the arc is to begin , hold down the left mouse button and drag it away from the starting point, then release the mouse button. You will notice as you drag the mouse button around the arc radius and location change. Move the mouse around to where you get the radius you want then select that point on the screen.
Steps 12 through 16 give instruction on how to use additional tools to modify the entities you have created. In this step you will learn how to break a line.
Step 13 will instruct you on how to trim line 6 back to line1. To break line 6, simply select the Break icon from the Operation tool bar. Select line 6 as shown in Figure 1.
The line will highlight then select a location on the line where you want the line broken. For the purpose of this lesson select approximately three Graduation lines from the left end point Figure 1.
The line is now broken. The easiest way to verify this is to select the broken line, only one of the two line segments will highlight. Although the circle has been created efficiently, the circle is unlikely to be moved from the origin in this example, and therefore would have been more appropriately created as a Circle: using the origin as its centre point.
Define the 35mm oblong profile 2.
Create Pad and define an R25mm circle 1. Select Exit: and then Pad: Enter a Length i. Create concentric R25 x 20mm cylinder 5. Create an R25 x 60mm cylinder 4. Crankshaft Part continued 4.
The circular profile can be defined to be always concentric with an edge of the Pad With the circle still highlighted as the current elementThis will bring up the Tools pop up window as shown in Figure 1. For example, if you selected Figure 1.
Sketching with the Profile icon radius option 1. Although the circle has been created efficiently, the circle is unlikely to be moved from the origin in this example, and therefore would have been more appropriately created as a Circle: using the origin as its centre point.
When the profile is highlighted you can select the Pad icon. The values attached to the Chamfer and Corner are constraints. The symbol is shown in Figure 1. The box will contain all the possible constraints but not all will be selectable.
Notice that the entire profile expands and contracts as you drag the mouse button around.
