I found DeltaCad, but it is trialware.
When I'm making paper templates for blades (cut lines for the lead edge, trailing edge, and chord), it is MUCH, MUCH easier to enter all the measurements in as coordinate points, then draw lines between them.
Longer explanation below, but I found DeltaCad would do it. Surely one of the free programs could do it. I've tried several so far, and most don't seem to be able to do this. Of course, I'd be the first to admit that it's me, not the software that is lacking...
Explanation:
If you have all the measurements for a blade, you can use X,Y coordinates to design the template. For example, if you're using a 2x6 that is 24 inches long, you use these numbers to make the rectangle shape of a board:
0,0 -24,0 0,1.5 -24,1.5
Then you can plot out your leading edge using the numbers you get from your software. The "x" coordinate is the "Radius," and the "y" is the "Thickness" from calculators like Alton's or from Ed Lenz here on the board.
If you can print it out at full-size (uses about 3 sheets of paper in my example for each template) then it's the simplest way I've found to make a template with the exact measurements. You could do 20 stations this way if you were really hardcore.
Hopefully the numbers won't get screwed up here.
Anyone have any suggestions?
Basically, I want to be able to put a dot at, say, 0,0 by typing in that number - NOT by moving it around until the cursor happens to be at the right place. That is both inaccurate and tedious.
