Dan,
FreeCad is free and a viable option. I don't use it so I probably can't help you
get started with it. As with any Cad program the learning curve is pretty steep
but if you are willing to spend the time learning it will be a lot of help
in the future. When I went from CadKey to AutoCad there was a lot to learn.

Dan,
I found Excel plots aerofoils quite well directly from the co-ordinates.
This is what I used to plot the Riblett 612.

Here is a microsoft excel spreadsheet that will calculate the thickness, tangents,
Angles, and length of the airfoil Chord at each station. I've attatched it
as a PDF. The notes on the sheet should allow anyone to create their own spreadsheet,
but if anyone wants the actual spreadsheet send me an email and I'll
attach a copy for you. I also have a spreadsheet that calculates that dimensions
of a Clark Y airfoil for any given Chord length. I simply draw the airfoils
on graph paper. I need some CAD software to draw the airfoils...

you can pick up the '32 flying and glider manual with the original drawings for
about 6 bucks from the EAA or Aircraft Spruce.... the '33 edition has the single
seat version and some better detail drawings of some parts than the '32..
here is a link to them online .... you have to download a free viewer.. i look
at em all the time...

OK ! I used the scattered graph to plot the Clark Y airfoil for my propeller.
How do I scale the graph so that when I print it is in the correct scale ? In
this example " Inches " PDF attached.

Subject: | Re: Rib stitching help |
A helpful hint for rib stiching. Measure and punch all rib stich holes.
Put a light on the opposite side of the wing by the hole you want to use.
Look into a hole next to the hole you are putting the needle into. You can
see the inside the wing and guide the needle to the correct hole. Works
great. Brad Williams

I have been using IMSI Turbocad for years. While not free and older version than
current is pretty cheap. For the 2D version 16 it is about thirty bucks. The
best part is that they have CD's that teach you how. Been a while since I have
needed to watch one. Memory sludge serves up an english schoolmarm sounding
voice and the cursor moving to the various places to make things happen. You can
stop it and go to the program and do what was shown and said until things click.
For 2d the learning curve is about a day. 3d? Just get the nail gun!
