One of the most difficult operation in Surface Design in CATIA V5 is to keep tangency in situation like the following.
It’s necessary to design a flange (bending/forming on sheet metal) which the guide is a slot profile on curved surfaces. First times was impossible to give a thickness to the surface because the flange was not tangent to the slot profile.
If the slot is on two or more surfaces, a simple sweep does not ensure the tangency.
In a situation like that, I always do this kind of operations:
– Parallel Curve (Slot profile)
– Projection of Parallel Curve (On upper plane)
– Line (or profile) to connect slot profile and parallel curve
– Sweep (with two guide curves)
– Edge Fillet on edge (Bending Radius)
– Other optional Splits
