Newbie trying to model violin face with arching

[paragonwwks]

Hi...I have been briefly tring gmax to model an accurate violin face surface ...I have the outline and am able to make a contoured surface but keep getting creases that I am not able to figure out...i do not want to give up so , does anyone have any guidance for this or something similar as far as tutorial or any other help that could be used to be able to successfully make this part. I know gmax is no longer supported but it seems as if 3ds is very similar though superior...

Thanks for ANY Help!!!

Hi...Here is one example...the long spline originall was a nice curve but
after i refine connected cross splines it gets straightened out and
jagged....main problem is bulges as profile shape turns sharply....am I
using the wrong method altogether?

Thanks!!
