Nurbs Patch Modeling

I wonder if any of you might have the same problem as me when you approach to modeling is making Nurbs patches then connecting them b converting to something as I call Editable patches like the on available in Max and to avoid Trimmed Surfaces If anyone knows the best technique to convert Nurb Curves and Surface to Splines and patches without changing curvature and tangency an position of points on the original surface. I tried to export them a IGES to Autocad, Max and Solidworks but not yet satisfied with th quality of resulting Surfaces. I found the Project Tangent tool i Maya extremely useful to make Surfaces matching in Curvature thos any other software have the same feature

At this point, the only real option that you have, when it comes to Solidworks, would be to use Shapeworks.

Its a plug in for SW that lets you take any surface, places a NURBS patch over it, change it, and then bring it back into SW. Since it is a gold partner you never have to leave the SW environment in order to make the changes.

The curvature tools in SW are much better than they use to be, are they on the same level as Alias, Maya, or 3D Max....not 100% yet, but each year they do get closer.

If you are most comfortable using non-parametric systems like 3D Max, Maya, etc, you won't like working in SolidWorks. It sounds to me like you are trying to get SW to work like those tools, which generally doesn't work out the way you might expect. Even the BarenBoym Shapeworks tool someone else mentioned is non-parametric.

If you are having translation problems, obviously make sure that it's starting out from Maya correct, and that the translation will round trip back to Maya correctly. Rather than Iges, do you have access to STEP or Parasolid? Those are both better translations to SW.

SW has a Fill surface which in some situations can avoid trimming surfaces. Even the Loft can sometimes avoid trimming to fill in an area. Why the requirement to avoid trimmed surfaces?

SW does not have a surface type where you can tug-and-pull NURBS grid points.
