AFX/EFX replace tube/profile

Hi all,

I'm working on a framework where all tubes have to be replaced by an other tube...

Can that be done by some simple changes/instructions or all need to be redefined by AFX?

Re-assign new profile and regenerate or ....?

>>> 30x30 profile was used, now it needs to be 50x50

If I edit the extrude in each tube, my positioning by AFX is not ok anymore

Thanks,

Didriek
