FAN BLADE IN CATIA V5

1. Step 1Create the base on which the blades will be made.Create a point on the lower edge.

2. Step 2Similarly create a point on the upper edge at a certain lateral distance from the first point.

3. Step 3Create a 3d line between the points and choose support as the lateral face of the padded object.

4. Step 4Switch to GSD Workbench

5. Step 5Extrude the line along zx plane

6. Step 6Invoke a sketch on xy plane

7. Step 7Sketch the shape of the blade and make the end coincident with the edge of the padded object.

8. Step 8Exit the sketch

9. Step 9Extrude the sketch with reference as the xy plane

10. Step 10Split out the unnecessary parts by using "split" command

11. Step 11Hide the extruded part which is not necessary

12. Step 12Switch to mechanical part design workbench

13. Step 13Insert->surface based features->thick surface

15. Step 15Tools->hide->all surfaces

16. Step 16Click on circular pattern

17. Step 17Fill with appropriate parameters
