Default Those aren't full-size drawings

THESE are full-size drawings!

No tracing, lining up sections, or cutting up originals.
Since I've decided to go with a bigger-than-plans fuselage, I copied the Aerocanard bulkheads into CAD, then edited and adjusted to ensure I would maintain a good shape full-length. Also included a few tweaks I've picked up in research, such as slightly over-size engine mount hardpoints.

Didn't take too long today to cut out the shapes from the big sheet. Now to transfer to foam!

That looks great! A lot of work, but worth it!

Kinda takes all the fun out of making all those mistakes, and panels not fitting right, though!

so ..... curious.
How did you convert drawings into CAD?

Lots and lots of measuring, checking, and remeasuring each line on the drawings, and inputting that into CAD.
Since the top profile is a bit different, I'll use the CAD generated profile to refine the fuselage side jigs too. Hopefully things will fit with minimal tweaking and even less filler!

Default Re: Those aren't full-size drawings

I wrote a little program that would allow me to open a scanned jpeg file, establish the scale and then select the type of line/curve you were going to work with and then convert your clicks to plots in a file you could import into CAD.

I've used it to convert some of the Mistral engine drawings (jpeg) into CAD.
This is also how I copied an actual P-51 scoop setup into CAD and scaled it to fit my Long-EZ.

Time consuming either way.

Yep, time consuming, but it certainly helps one become familiar with the drawings and associated plans! Fingers crossed this saves time and improves quality of the actual aircraft.

I watch your work with interest, as I am planning a turbo, liquid-cooled engine, and am also going to be vacuum bagging as much as I can. I've almost finished dialing-in my 'sorta-low/medi-vac' system on test pieces.
