I posted a "limit-case" ;)
If we need just to fill a hole,like in this case,we can use -NSIDED-, or select ABCD edges and choose NETWORK, or select AB like sections and CD like rails and do the SWEEP
all three solutions will make a patch...... without a continuity,this means that if you do a close-up you can see the seam
Different situation if we want to have a continuity of curvature (G2) between the new surface and,at least,BCD surfaces
This is an high-end feature that maybe only ultra-expensive modelers can handle,often called also CLASS-A surfaces (a typical case where this feature is required is car-modeling for manifacturing)
Actually, in MOI,we have just BLEND that allow a continuity choice,now improved with multi-chained edges
if in future we will also have a continuity choice in NETWORK we will able to make cars much more better
Thanks again Michael ! :)
