I think MoI actually a good and mighty tool, for that Price, when you must go deeper in the Nurb-Surfacing-World you must use Tools like "Alias/Autodesk Class-A Surfacing", "Solidworks", "NX" or "Catia", but the prices of this tool are about 6000€-30000€, a year, a cheaper solution was the VSR Shape Modeling plugine (300€ 2012, I think) for Rhino, but it don't exist anymore, Autodesk has buyed it and now you must buy Alias A-Surface-tool, I think at now it costs 10000€ a year.



Here you can read the limitations of polygon vs nurb modeling

Hi zarkow.

Thanks a lot for your info :)

@You : "...Here you can read the limitations of polygon vs nurb modeling..."

In fact in my latest post I was referring to "non real-world/production modelling" but fast poly/sds box modelling that is more than enough for rendering only purposes.

Bye.

Another way: the T-Splines in free use for enthousiast, hobbyists, students even Start Up ! ;)

Sems CMorph by Max Smirnov inside the car's toolbox can be useful in some cases ?

You can input number of curves between Start End!
For multiple profils just repeat the process like here :)



LineWeb also for create some patches surfaces between curves?

You can input number of links...

Interesting, but when you make first Network patches, you can see the light flow on surface better.

I need a script, than can analyse the isospline that lays the Isocurves automaticly on the Isocurves of the neighbar patch, but I think it's very complex.



another script idea is maybe, if you could pin or snap automaticly the polygon vertices points temporary on the (red) controlsplines, after the retopo work, than it would be posible to control the meshflow better.





or


and my second idea is a kind poly UV iso spline (U=green + V=orange) loop selection script, for later clean up the patches, at now I must select all edges manually to make a Network




And there is a before/after shot


to this

OK, a patch cleanup is with Fusion 360 the easy way:

-Export in Moi to obj:

-Open Obj in Fusion

-Convert Quad to T-Splines



-Convert T-Splines to BRep



-Export in Fusion to Iges

Open in MoI




Clean.

A patch process can be! :)
