    Hi,

    I'm modelling a Fokker DViii, this is a parasol WWI fighter.

    The upper surface of the wing has no dihedral but the lower surface tapers upwards towards the tips meaning the tops of all ribs are level but the rib depths shorten towards the tips.

    I've included a link below to an image of what this looks like.

    Is it possible to model this in DevWing?

    Thanks.

    Yes, just select the right airfoils to have thinner sections at tips and apply the right dihedral angle at external panels

    Thank you for your reply duroneee.

    I cannot see how to apply 'dihedral' to only the underside of the wing leaving 0 degrees dihedral for the top surface as per the prototype.

    Whichever dihedral definition I use the whole wing becomes angled?

    I have added a link to a screenshot my panel settings below, hopefully I have misunderstood your last reply.

    Thanks.

    Once the external panel has the right thickness tapering, apply the right dihedral angle to get the upper part aligned.
