Excuse the childlike drawings I only had my iPad and my finger. Visual representation of my idea from earlier post about a wing builder as something that's meets the custom wing needs procedural provides but keeps the Lego build things to experiment vibe that I see is now in OP's first post Thanks allmhuran Parts list for wing builder with the skeleton list of parts Root part should be size tweak able Wing construction, use wing edges like you would the I beams we have now. Stacking them (maybe tweak ale to bend curves into them) to get wing shape. And spar to influence over strength of wing and eventual weight. Then when the wing is "built" you get a pop up "complete your part" box. Let's you pick options, for example does it hold exploding juice? Is it covered in kerbal heat paint/wing skin type is skinned in metal or Jebs trousers? Does it have flaps or control surfaces built in? What's the spar made out of, tin cans, chair legs, kerbaltanium? Maybe the option to adds bends or curves to the spar in places. Perhaps you could have very basic airfoil type options, high altitude wing, acrobatic wing etc to give different modifiers to the wing properties. Once setup this wing is now one part (except if it fails maybe it could half break or something...as I hate the idea of building a huge wing and when it fails the whole wing vanishes like single parts now do...the great part about a compound part wing is when if fails its a lot closer to a real wing failure analogue then an entire massive procedural wing vanishing
