Hi all,
Am a basic user of NX and would appreciate any suggestions as to complete the surface modelling in the attachement. The curves were extracted from cloud points.

thanks
 
My first impression when I look at the picture is: the curves in the lower right of the screen have some undesirable shape changes happening. I'd suggest cleaning up/smoothing out the curves before proceeding any further. Surface modeling strongly adheres to the Garbage in/Garbage out rule.

Thanks Cowski,
but any suggestions on how to complete the shape?
 
The image you supplied doesn't give much information on what we have available to work with. It's therefore difficult to advice.
In general, "all" surfaces are four sided and in the ideal world rectangular. I the real world the rectangularity almost never happens.
Since surfacing is a form of approximation of a desired shape, maybe you need to create some curves that you can use to define the missing surfaces.
A surface cannot guess the shape it should have, you need to guide it into that shape with some curves.

Regards,
Tomas
