I know that Modo is primarily a sub D modeler, but I wanted to try patch modeling using splines. I realized that spline modeling is not the strong part of Modo, after fiddling with the functions for an hour.
First, the patched geometry looked OK, until I thickened it. Suddenly I see seems and unwanted gaps everywhere. After trying to make a shield using a different method, I came to believe that edge extend is the best way to model things like cars and things with smooth, organic surface.
BTW, thicken command also doesn't work as I planned. I do turn off the symmetry just in case, but the end result often looks broken and manually fixing broken geometry is just time consuming. Or, maybe I fail to realize that it's all part of the modeling process as usual.
I will post the Youtube video I uploaded.
