3D "Bend"

The attached is a model of a bodysurfing handplane that I am attempting. Is there a method that would enable me to "bend" the tip upwards? (so that it would ride in the water more efficiently).
Also since this will be a 2-sided model can I flip the model in Aspire, or do I need to re-model the back side?
I have been trying to no avail to bend the tip, but I see no method to accomplish this.


Thank-you

Have you tried using multiple cross-sections for your 2-rail sweep?
Also your two rails are kind of ragged. If you did that by auto tracing a bit map, try just tracing by hand and then "fit curves to vectors" to smooth it more.
You will need to model the top separately.

Mike;

Thanks for the tips. I never thought of multiple 2 rail sweeps. I am still not sure how I will be able to "bend" the board tip forward keeping the same edge thickness. Maybe this is not possible with Aspire. I may have to find another modeling software package (3D Studio Max apparently has these functions, but is very expensive).
Does anyone have any cheaper alternatives?


Thanks

Greg
