Thanks again, yes I understand now.
The way I did it In some of the other pictures I found by basicallly 'screwing round with it' untill it worked......

What I did was to...
(a) Select bottom of curve "column" using "surface point" and move it up the column a bit, then do "Insert Isoparms"
(b) Select the base part and do the same moving the "surface point" outwards this time before "Insert Isoparm"
(c) Then I shift selected bothe new Isoparms and did the "freeform fillet"
I tried the other 2 types of fillet but either got wierd results or an error.

I now see that yours is the method to use because you are getting rid of unrequired surfaces, whereas I had been leaving them "hidden".

I would also like to find out about the other types "Circular and Surface" filleting. (Also got my Birail Propellor to do yet)
I must admit I did pick this "Fan" subject to learn more Nurbs, but didn't think I could learn so much one just 1 object.


(Oh and I will be reading through that thread about 'gaps' although I have got rid of most now by increasing tesselation).

I will use your method and re-fillet the neck on the model, this is the model using my old [B] wasteful [B] method.

Regards and thanks, Scraggy
