In this third episode on CATIA Relational Design, I would like to showcase some other scenarii that can be performed thanks to this powerful approach.

After driving geometries of mechanical parts by geometries defined and published in skeletons, here I will focus on scenarii in which mechanical parts geometries aredriven by parameters created and published in skeleton(s).

Importing these parameters from skeletons into mechanical parts can be performed in the same way it's done for geometries:

• either by Copy parameters in the skeleton and Paste them as Result with Links in the mechanical part
• or by direct selection of skeleton parameters when creating formulas inside the mechanical part

The result is then external parameters (and formulas), using publication information, inside the mechanical parts.

Now, we can imagine several scenarii.

First, we can for instance modify the mechanical ribs width value defined in a skeleton and see the impact on all the ribs of the inner wing structure.

Second, we can do the same kind of thing on the rib thickness of the external structural parts.

To be continued in a last episode...
