A lot of designs with the swoopy lines, rounded periphery, strakes, etc. aren't easy to measure and make me more skeptical about using an on-line computer instead of going with chalk lines on the workshop floor.
To retrieve valid dimensions to plug into Geistware, I've had to do extensive layout work anyway. Still can't bring myself to not using my T squares and triangles to get a ball park idea.
The ball park idea works like gangbusters in Geistware.
To retrieve valid dimensions off a chalk outline would take you how long?
I'd bet with your experience, you'd have measured that wing the with the same estimations done in the attached picture. The attached is how that wing would be measured for Geistware. It took me longer to draw the picture than it'd taken me to measure the same way shown with a yardstick.
The orange lines are the root chord and tip chord. Yup, they're estimates. The red is the half-span and the green is the sweep. And yes, the sweep has to be done "in the air". Good of you to mention T-squares. The sweep measurement is more accurate if you have some reference line to work with. Figuring a means to do that accurately takes no less effort than working up lines to draw on paper, wouldn't you say? Of course, if someone is about to suggest that often the lines are already drawn on the plans................ measuring the plans is easier than blinking your eyes.
