Visual discontinuity in seemingly simple surfaces

[TomTom (Tom)]

What rhino commands do you use on a regular basis and think others don't know about?

In Rhino, very often I use the _split command with the Isocurve and Shrink option on. This allows me to create perfect blends. Another tip, when using the blend surface or curve surface command I use the “Shift key” to move both ends equally. Very useful. [splitIso]
