Wing spars and ribs modification

[pablorodriguezotero]

Hello,

I am currently working on a wing parameterization.
The starting point is a CPACS file where the skins and the internal structure is already defined.
I got the job done for the external shape of the wing, however Im struggling to make the spars change accordingly.
I have tried to find the tigl functions to access the spar position to modify it, however I did not find anyone. This makes me think that maybe my approach for the structure modification is not the right one.

Any suggestion?

edit: To be more specific, im looking for the method to modify the eta and xsi values of a spar position
