How to avoid twisted surfaces

Hi!

 

I am making a model of a traditional norwegian hardanger fiddle, and it has som challenges. The geometry is quite complex, and to achieve a model with both outside and inside geometry I have made some profiles and 3d-sketches and used a lot of lofted surface. Then I extrude material to the outer surface, and try to remove with a cut to the inner surface.

See the attached files

The model is almost perfect and quite sofisticated . It works well parametric, and will be a fantastic tool for me and my cnc-mill.

 

But my problems is to achieve nice surfaces ecspesially around the F-holes, which are quite complex on this type of fiddle, This gives my problems with making the last extruded cuts which goes in to the inside of the plate.

 

Any of you guys who can give me som good advice about defining the surfaces in this geometry? Is the main idea about sketch structure wrong?

 

Best regards
