I found a useful program (actually recommended by another RCU member) called AreoPlot http://www.cncplusplus.com/index.html Scroll down to Hobby software. If you go to the UIUC airfoil data site you can get all the info needed on hundreds of airfoils (link) http://www.ae.illinois.edu/m-selig/a...atabase.html#N. Oh, never mind the link is built right in to Aeroplot....

You can play with the airfoil in Areoplot and export it as a DFX file. These obviously can be imported into your cad program and manipulated from there. If only I could make Draft Sight make multiple ribs with the appropriate spacing, for a tapered wing panel, I'd be golden. I'm a newb with CAD so I know next to nothing

I played around with a low Reynolds number airfoil (Selig S8035 ). I made the root 10% thick and the tip 15%. The two following attachments are a PDF. I don't know how (yet) to get both images one sheet of paper.
