1. DRAFTING TECHNIQUES I 136

2. 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. 137

3. 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. The first thing that needs to be done is to make the background active by going to EDIT and then BACKGROUND. 139

5. Once in Background, you will notice that the new toolbars 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. 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, don’t forget to go back to EDIT and turn the Working Views back on. 141

7. 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 we’ll use the front view. 142

8. 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 143

9. Now we have an ISOMETRIC view of our part. There are many other drawing features Catia offers. A few are as follows… 144

10. Hidden Lines. To add them, pick the view you wish, go to Edit and pick Properties. 145

11. Once in Properties, move down to the Dressup box and activate the HIDDEN LINES box then click OK. Highlight this box 146

12. 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 here to start Click here to finish 147

13. 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. Place the SCALE circle where the you want the detail view to be. Click once to place the circle. 149

15. 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. 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. 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. 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. 153

19. Click PATTERN TABLE Then choose your pattern 154
