Here is a basic shape. From here, we will do some advanced

drafting once we put this shape on a sheet as a drawing.

Select this face,then go to drafting.

From these simple drawings there are many

things you can do to make your drawing more

descriptive.

Adding a Title Block

138

The view you

picked will now

be the front view


4/19

The first thing that needs to be done is tomake the background active by going to

EDIT and then BACKGROUND.

139


5/19

Once in Background, you will notice that the newtoolbars you have a much more sketcher like, and

one of them is FRAME CREATION. This is the one

that you click on to make a border and title block.

140


6/19

Once Frame Creation is chosen, the Insert Frame and Title Block

dialog box will pop up. This is where you can add and modify the

border constraints for your drawing, and add a title block size

constraint if one is required.

Once you have chosen what you want and clicked

on OK, dont forget to go back to EDIT and turn the

Working Views back on.

141


7/19

Now we can add an isometric view of our drawing.

The first to do is click on the ISOMETRIC VIEW icon

and chose the view of the drawing that you wish the

isometric to be of.

Here well use the front view.

142

Catia will ask you for a plane on the 3D part for it to draw from. The easiest thing

to do here is click on VIEW and chose TILE HORIZONTALLY. Now you can see all

of your work, and when you pick a plane (as shown) you will see it automatically

update itself into your drawing (as shown). The 3D part in your drawing can be

moved until you click on a place for it to stay, then it will become a line drawing.

Choose a plane here

Move your 3D part to where you want it

Now we have an ISOMETRIC view of our part. There are many

other drawing features Catia offers. A few are as follows

144

Hidden Lines. To add them, pick the view youwish, go to Edit and pick Properties.

145


11/19

Once in Properties, move

down to the Dressup box

and activate the HIDDEN

LINES box then click OK.

Highlight this box

146

Another thing to add is a SECTION VIEW. Choose the Section View icon, draw the line

through the part to be sectioned (as prompted) and place the view by clicking one

more time once it is placed where you want it.

Click

Click here

to finish

A DETAIL can be added by clicking on the Detail icon and making the

circle around the part to be viewed when prompted. Click once to start

the circle and again to end it.

148


14/19

Place the SCALE circle where the you want the detail

view to be. Click once to place the circle.

149


15/19

Your detail view is now finished, with the correct balloon indicating and identifying

it. If other details are made on the same drawing, they will be numbered

sequentially.

150


16/19

Another useful tool is the CLIPPING. It is like the detail view, but in reverse.

Click on the Clipping icon and place the circle the same way as you do a

detail.

151


17/19

The difference between DETAIL and CLIPPING is what you are left with. Here,

you are left with only what was inside the circle, scale 2:1. The final view is placed

be clicking once where you want it to finally be.

152


18/19

You may have need to change the hatching on a section view you

have done. This is accomplished by choosing the hatching (as shown)

and going to properties in the edit menu.
