Create a spere

 Surface creation in MOI Task is simple, create a surface from 3 connected arcs, which should lead to a sphere shaped surface. see from left to the right. I used the “Network” function. the second shape is the result, one control point is totally asymmetrically placed. Why? Then I use symmetry to create a half sphere - an you can see sharp edges. Then I patched the original surface to make it symmetrical - and now the sphere is nice and smooth. Now i tried to find the cause of asymetry. I added control points to arcs. Now I see the asymetry There is a difference in order how the curves are selected befor the network command is applied. Another trial: using the sweep function: Sweep is OK. It creates a symmetrical control point set, and the sphere is smooth. Unfortunately, it creates a huge amount of control points, making the surface practically un-editable Quite near the victory I tried to use sweep for 3 free curves. And again: this does not work, system creates a strange artefact on top. Back to my previous post: How to create a smooth surface, with minimum control points controlled by 3 different curves, assuming that the surface touching the curve has the same perpendicular as the curve in that point.

 5296.4 In reply to 5296.3 Hi Michael this was only my exercise how the surfaces behave in various conditions This is the most important information for me: >Network acts kind of like applying a film over the shapes, it has a sort of "tension" Now I understand my faults... But I have a related question (or request for next version :-) is it possible somehow to control the that tension of the network? Or will be possible to control the continuity like with blend command? thank you very much for spending time and effort Jozef

At the moment there isn't any way to control it inside of Network. But I am planning on working on some more kinds of continuity controls for v3. - Michael
