Modeling approaches to representing the joint
Problems:
Modeling environment does allow for pressure fit joint but not for joints forces into place out of position - meaning that if their fit would be loose they could be assembled without force Attempt at modeling two adjecent ruled, developable surfaces, with the joint piece bridging over the ridge line -crease Double curved attempt-modeling the surface strips as smoothly deformed double curved strips.
Conclusion: CATIA does not support the contact/pressure fit joint for complex surfaceobjects as it is the case in the seam curfaces in these examples.    
     
     
Simplified flat version of the joint without initial curvature. Curvature gets introduced later throug momentum.    
     
   

Neutral, undeformed state of the joint, which is being clamped around the two sectional sides.
The seamline is contected through a pressure fit contact joint along the elngth of the seam with an overlap of 0.001mm
