Another option. Go to shareware.com and search for Cad.In there is a program called TommyCad which is available for 30 day trial. It has a spline plotting function which is what you are looking for to smooth the curves. Most maneuvering is done using the F8 KEY. I think the file name is TSCAD5. Good luck JJ.

: Elk,

: Thanks for the offer. I actually have Turbo Cad 1.0 and might see what it
: does for comparison. Can you give a brief description of your method (i.e:
: did you set up Turbo Cad as a graph and just plot points or inter the
: offsets somehow)? However creating the offset drawing itself is not my
: problem. Putting all the info (except the diagonals which are unique to
: the Guillemot) into the spreadsheet, transferring the graph to Freehand,
: and resizing to proportion yielded the drawings. What I don't understand
: is how to figure out what the "diagonal value times the cosine of the
: angle" and "diagonal value times the sine of the angle plus the
: starting height" is. I know that the formula can be programmed into
: Excel and it will do the trig. for me, but I don't know how to write that
: formula or what numbers to use where.

: One last thing. In Turbo Cad, could you get a fair curve to connect the plot
: points? I know this is not important as I can do it by hand after
: printing, but part of the reason for me doing this on the computer is for
: me to actually learn some more about the software on my hard drive. I'm
: sure it can be done in Freehand, but I haven't figured it out yet. Anybody
: have advice?

: Thanks again, David
