Hello all,
I am quite new here, and I would like to create the model of a railroad coach. The critical part is a corner of roof: there are 3 different curves and I don’t know how to cheat MOI to create a nice smooth surfaces...


I tried a various approaches, but always I get sharp edges on surfaces, or curious shape ...









And unfortunately the critical surfaces have a “millions” of control points, so i am not able to adjust it simply...



Is it possible to reduce somehow the amount of control points on surface?

Any advice is appreciated :-)

I tried to discover what’s the problem and found a couple of surprising “rules” or behavior, i don’t understand. But it’s better to start a new theme.
