How to convert enclosed surface to solid in CATIA?


Follow the steps to do the thickness on the surface

  1. Step 1:

    Create the piston which you wanted create the thickness

  2. Step 2:

    Go to Start -> Mechanical Design -> Wireframe and Surface Design

  3. Step 3:

    Select the Offset Tool from the Surfaces Toolbar

  4. Step 4:

    Select the surfaces to create a offset surface on the piston surface and enter the required dimension

  5. Step 5:

    The surface is created as shown

  6. Step 6:

    Likewise the other surfaces are also created by clicking on the surface

  7. Step 7:

    Other surface is also created from the given part

  8. Step 8:

    Same process is repeated for the other surfaces as below

  9. Step 9:

    Other offset surface is created on inside surface

  10. Step 10:

    Another surface is selected and click ok to create a offset surface

  11. Step 11:

    After that the surfaces looks like this.

  12. Step 12:

    Click on all the surfaces and click on Join Tool from the Operations toolbar as shown below

  13. Step 13:

    Click on OK for the surfaces to Join

  14. Step 14:

    Go to Start -> Mechanical Design -> Part Design

  15. Step 15:

    Now click on the Insert on the top and insert a body

  16. Step 16:

    Now click on the Thick Surface and select the surface to create a thickness from the surface

  17. Step 17:

    Select the direction to which it has to be created and enter the thickness

  18. Step 18:

    Now the thickened surface is shown below. And hide the surface if you want to hide it

  19. Step 19:

    Apply the material to differentiate that they are different

  20. Step 20:

    I have sectioned it to see the difference between the two materials
