Building a crowned surface is a very common challenge in CAD, and one that can be tricky to the uninitiated. Several people have asked me how to model the back of an iPad lately, so here I’m going to show the basic idea in a couple of very quick vids. I hope this helps!
I’m using Rhino on the Mac, but the process would be identical in Rhino for Windows. The basic concepts here would also be the same for Alias, SolidWorks, ProE, or basically any other CAD package. Happy surfacing!

Hi Adam.
I’m NX and SW user and just a couple of days ago i’ve started to learn Rhino and i faced some problems with sewing surfaces.. it’s not the way it works in other CAD packages. I made a loft surface and surface from network with the same u and v degrees that have one adjacent edge with G1 continuity between them and tried to sew.. but i coudnt. I noticed that their isocurves dont match and i know that’s the problem.
What am i doing wrong? And can u tell me what’s the best way of joining surafces with different isocurves.
Thanks
