Need help to create a wing in 3d using imported profiles.

If you could do it in steps that would be appreciated.

Thanks for the reply.
I haven't even tried it in solidworks, I only have Rhinoceros v4.
In Rhino it's fairly easy but I want to do it in ZW3d as this is the way I'd like to go in the future, plus there are a few things I don't like in Rhino(parametric and its slow).
I'll compile the foils and layout and will post them here as soon as I get to my PC at home.

Hi Randy,I've added the file in DXF format.
Let me know if it comes out good, mine is good most of the way.
Next step is to make a mold.

I have shown one solution with the info provided. but a number of others exist.
I have guessed where to split edges. This can make a difference to outcomes.
You don't need split section profiles and you can work directly off NACA foil data in a spread sheet.
ZW can suck in multiple profiles curve point sets in a single csv -delimited file which can be set up in the spreadsheet to produce all your curves! e.g you could build a spreadsheet wing modeller then do the solid modelling in ZW in a few clicks.
All you need is the point data for each cross section, if they are the same section, no camber changes etc, then you only need one section curve. and a couple drive curves.
I have worked with the dxf data raw, which produces poor results because the underlying curves are not tangent. The resuktant curvature disruptions are highlighted in the pic.
If you want tangent continuous surfaces you need good curves underneath.
Better - to complete a slpine as a single curve then split is later or use tangency constraints is multi curve/spline etc.
IMO The wingtip end termination is not realistic as transition to razor edge is always problematic.
FYI I've been there with SWx - it's not pretty.

ZW3D will do anything you want - and GIGO.
