CATIA - PARAMETRIC

1: Open a new file2: Insert a new body

3: Rename this body: third button on the name

4: Sketch a new profil in the plan yz

5: Add some Symmetry constraintsSelect the two lines first then the symmetry axis

Draw the profile of the beam

6: Create all the dimensionnal constraints

7: Edit the cotation and enter the correct values

8: Exit the sketcher

9: Extrude the profile

10: Choose a length

11: Select a profile

Extrude the profile

12: Create a edge fillet with constant radius

13: Enter a value

14: Select the edges

Create the edge fillet

15: Select the iconF(x)

16: Choose a lengthtype parameter

17: Create a new parameter

Create the parameters

18: Rename the parameter b

19: Enter its value

20: Select “Apply” to confirm the parameter creation

21: Do the same for the other parameters: h, e1, e2 and r
