    If you review the my post from 06/25, using an 'x' scale of 1 for LE to TE will generate an airfoil 1" long; then you scale it up by a factor of 63 which will make it 63" long LE to TE.
    It is unclear where you are lost. Please review my detailed previous posts in this thread and try to duplicate them. There is even a 'pack n'go' of the files to download to step through
    the procedure.

    Hi Christian,

    I have reviewed this / your previous post and have read them carefully, and know this is a VERY easy operation to someone like you but I am a blithering idiot when it comes to SW.

    How do you use an "x" scale and increase it to 63"?
    How do I project the splines?

    I am lost and I am sorry if this seems like common sense to you.. but it's CLEARLY NOT for me.

    I am trying to make this so I can print it out and layout my ribs.. any suggestions?

    To print it full scale, create a drawing with the view of the part normal to the rib.
    Under 'Sheet Properties' make sure the scale is 1:1
    Un-tick Display Sheet Format, and tick Custom Sheet Size: I went 65 x 10.
    In the normal view, create a horz line and some vert lines at each segment of some
    equal segments; I did 10"; This will give you something to align to and to select for printing.
    Save. I also left the 'spar' sketch visible in the part. (My 'spar' rectangles are random for demonstration)
    Then select print, under Page Setup, set to 100%.
    For Print Range select 'Selection'; a rectangle will pop up and move it to the portion of the airfoil to print.
    You will have to do this seven times.
    Each sheet will come out perfectly at 100%. Align the sheets with the horz/vert marks and tape together.
    See the .jpg; hope that helps. You should sign with your actual name.

    I see you posted an O-57 drawing. If your project is an O-57 or L-2 and you have the drawing CD set, you have enough info to plot the airfoil full size without scaling from the theoretical ordinates. The actual profile may be slightly modified from the NACA profile. The 23000 series typically is modified to remove the cusp. I made a jig for wood ribs from those drawings and it didn't take that long. As you can see, I plotted it directly on the MDF. The shipset of ribs was done in about 6 weeks including creating the jig and all the routing templates for plywood parts.

    If you really want to get it in SolidWorks either as an exercise or for further use, consider using the dimensions from the drawings to draw it full size in SW.

    I am still learning the basics of SW and eventually (.. within the next week) I am hoping to have it complete to print out.

    PS, my plane is an experimental BC-12 that will have a few more features than the original.
